In fulfilling this vision, one of Parks Victoria’s primary roles is to conserve, protect and enhance the environmental assets it manages. Parks Victoria has developed an Environmental Management System (EMS) to: support ecological management decision making; establish standardised reporting on ecological management performance; and develop targeted research, monitoring and reporting on the trend in ecological condition/health. This plan outlines key strategies and actions to protect and enhance the environmental values of Yarra Bend Park within the context of the Yarra Bend Park Strategy Plan, 1999. The plan provides a guide to set priorities for resource allocation for environmental management and forms the basis for reporting on Parks Victoria’s environmental management performance within the Park. 1.2 Environmental risk management in parks Parks Victoria has adopted a risk management approach to environmental management. This approach is based on the application of risk management strategies for the protection of identified environmental values. The first step in the process is the identification of the environmental values within the natural assets. Following the identification of environmental values, a risk assessment is performed. This involves the identification and analysis of risks to environmental values. Risks are given priority according to the extent of their impact on environmental values. The next stage is the development of management strategies to address identified risks. Targets for risk reduction and management performance indicators are developed to enable Parks Victoria to measure its performance in environmental management. Figure 1.1 below illustrates the cyclic nature of the system and, therefore, the opportunities for continuous improvement. Figure 1.1 The risk management approach to environmental management.

Comprising 260 hectares the Park contains the largest remaining area of natural bushland within inner Melbourne (Figure 2.1). 2.1.2 Planning framework Yarra Bend Park is Crown land managed by the Yarra Bend Park Trust under the Kew and Heidelberg Lands Act 1933. Since April 1997, Parks Victoria has managed the day to day operation of the Park in partnership with the Trust. 2.2 Aboriginal occupation Four separate Aboriginal tribes are known to have originally inhabited the Port Phillip region. Collectively they formed the Kulin nation or confederacy (Presland 1985). Each tribe inhabited a particular area of the Melbourne region. Various clans of the Wurundjeri tribe originally occupied the areas to the north and east of Melbourne, which includes the present Yarra Bend Park. The area would have provided reliable sources of water as well as a rich and diverse supply of plant and animal resources for food, medicines, shelter, clothing and tools. However, little evidence remains of previous Aboriginal occupation in the area other than several scarred trees along the Yarra River upstream of Yarra Bend Park (Yarra Bend Trust 1990). 2.3 European history 2.3.1 Park establishment Yarra Bend and neighbouring Studley Park were reserved in 1877. Both Park areas and several reserves were combined in the early 1920s to create one large park, which became known as Yarra Bend Park. During the 1930s additions to the Park included picnic and sporting grounds, toilet facilities and a public golf course (Figure 2.2). 2.3.2 Dight’s Falls A rocky bar across the Yarra River terminated Surveyor Charles Grimes’ river expedition in 1803. In 1841, John Dight established one of the first flourmills in the Port Phillip District at the rocky bar, later known as Dight’s Falls. The bar has since become one of the Park’s best known features (Figure 2.2). 2.3.3 Institutions A number of institutions were established on the land of Yarra Bend Park throughout the nineteenth century. These included the Merri Creek School (an Aboriginal mission School established in 1848), the Yarra Bend Lunatic Asylum (established in 1848 and decommissioned in 1925), the Queen’s Memorial Infectious Diseases Hospital (established in 1904, now Fairfield Hospital) and Fairlea Women’s Prison (established in March 1956 and closed in August 1996). 2.3.4 Urban development The Yarra Boulevard was constructed during the 1930s depression and resulted in greater public access and use of the new Park. The Eastern Freeway bisected the Park in the 1970s, but attempts to lay the Brunswick-Richmond power line through the Park in the 1980s failed due to strong community opposition (Figure 2.2). 2 2.3.5 Studley Park Boathouse and Kanes Bridge The Burn family established “Riversdale” in 1863, the first of many boathouses on the Yarra River. Now known as the Studley Park Boathouse, it is significant for its continuity of use as a public boathouse since its establishment. It is the oldest public boathouse on the Yarra River (Figure 2.2). Kane’s Bridge, a suspension bridge, was constructed over the Yarra River near the Studley Park Boathouse in 1934 (Figure 2.2). 2.3.6 Deep Rock The Deep Rock Swimming Club was established in 1906, and the Deep Rock Swimming Basin was a popular spot for competitions and recreational swimming for many years (Figure 2.2). The cliff opposite was the site of a world record 62.7 metre high dive by Alec Wickham in 1918. 2.4 Friends groups Since the Park was reserved in 1933, the voluntary activities of friends groups have made significant contributions to the management of the Parks’s environmental values. Currently, the most active of these groups include: Friends of the Yarra at Galatea Point; Men of the Trees at Deep Rock; Greenlink Yarra Bend at Deep Rock; Tree Project at various sites; Friends of Walmer Street Bushland at Dickinson Reserve; Growing Friends of Yarra Bend Park at the Park Nursery; and Friends of Lower Yarra at Andrews Reserve. These groups are involved in a wide range of volunteer activities including weed control, seed collection, revegetation, flora and fauna monitoring, plant propagation, provision of visitor information and track maintenance. 2.5 Climate Climatic conditions experienced by Yarra Bend Park can be generally described as ‘Mediterranean’, meaning a dry and hot summer and a wet winter. 2.5.1 Temperature Highest temperatures occur in January and the lowest in July. Mean maximum temperatures at Yarra Bend Park range from approximately 26 0C in January to 13 0C in July and the mean minimum temperatures range from 14 0C in January to 6 0C in July (LCC 1991). 2.5.2 Precipitation Precipitation is generally reliable with maximum rainfall occurring during winter and the minimum in summer. The average annual rainfall is approximately 655 mm. September through to December are usually the wettest months and January to March the driest (LCC 1991). 2.5.3 Wind Prevailing winds are from the south and north, which tend to increase in strength during the day. 2.6 Geology The oldest rocks exposed in Yarra Bend Park are marine sandstone and mudstone from over 400 million years ago. An excellent display of these sediments is at the cliff face at Dights Falls, showing faults and folds, layering and ripple beds of exposed ancient seabeds. 3 Lava flows from volcanic activity 2.2 million years ago and again about 800, 000 years ago, introduced basalt soils to the Park allowing a wider range of vegetation. An outlier of the Brighton sands over Silurian sediments occurs on high points of the Park. The Brighton sands are freshwater alluvial sands and gravel of tertiary origin. 2.7 Rivers and creeks The Yarra River winds through Yarra Bend Park from east to west and the Merri Creek runs along the northeastern boundary of the Park before it enters the Yarra River. The Yarra River and Merri Creek are important natural features of the Park, which provide some of the finest scenery, and opportunities for river based recreation within the Melbourne region. In addition to these values, the Yarra River and Merri Creek function as wildlife corridors for the following local, regional, national and international fauna. Local Movement: Mammal species such as Brushtail and Ringtail possums, bats and birds. Regional Movement: Migration of Australian Grayling and other fish species, birds and bats. National Movement: Migration of bird species including: Black-faced Cuckoo-shrike, Pallid Cuckoo, Fantailed Cuckoo, Horsefields Bronze-Cuckoo, Shining Bronze-Cuckoo, Azure Kingfisher, Sacred Kingfisher, Welcome Swallow, Fairy Martin, White Winged Triller, Olive Backed Oriole, Masked Woodswallow, Whitebrowed Woodswallow, Dusky Woodswallow, Restless Flycatcher, Leaden Flycatcher and Satin Flycatcher. International Movement: Migration of species listed under the Japan Australia Migratory Bird Agreement (JAMBA) and the China-Australia Migratory Bird Agreement (CAMBA) including the Great Egret, Greenshank, Lathams Snipe, White- throated Needletail and Fork-tailed Swift and Eastern Curlew. 4 3 Environmental Values 3.1 Ecosystems 3.1.1 Environmental responsibilities Ecosystem management is derived from a range of National and State Acts, Regulations and Policies. Those that relate to Yarra Bend Park and the management of the ecosystems within the Park are listed below. For the functions and major elements of each see Appendix 1. 3.1.2 Commonwealth Government legislation Australian Heritage Commission Act 1975 (Register of the National Estate) Yarra Bend Park is listed on the Register of the National Estate in recognition of its outstanding values and its importance as part of our heritage. There are approximately 200 natural areas in Victoria that are listed on the Register of the National Estate. 3.1.3 National policies and initiatives Interim Biogeographic Regionalisation of Australia (IBRA) Yarra Bend Park falls within two biogeographic regions: the Victorian Volcanic Plain to the west and the South East Coastal Plain to the east. The Victorian Volcanic Plain is characterised by an extensive basaltic plain with numerous volcanic cones and eruption points. The vegetation formerly consisted of damp sclerophyll forests, woodlands and grasslands (Thackway and Cresswell 1995). The total area covered by this bioregion is 2.2 million hectares, all of which is in Victoria. A total of 27% of Yarra Bend Park falls within this bioregion. The Victorian Volcanic Plain comprises the Victorian Volcanic Plain Victorian Bioregion. The Victorian Volcanic Plain bioregion extends from Melbourne west to Portland, south to Colac and north to Beaufort. The South East Coastal Plain is characterised by undulating Tertiary and Quaternary coastal plains. The vegetation formerly consisted of heathy woodlands, dry sclerophyll forests and heathlands (Thackway and Cresswell 1995). The total area covered by this bioregion is 1.8 million hectares, all of which is in Victoria. A total of 58% of Yarra Bend Park falls within this bioregion. The South East Coastal Plain IBRA comprises three Victorian Bioregions: the Gippsland Plain, the Otway Plain and the Warrnambool Plain. The Gippsland Plain bioregion extends from the Melbourne Central Business District (including Yarra Bend Park) and the Mornington Peninsula through parts of central and south Gippsland to Lakes Entrance in the far east. Table 3.1 summarises the contribution that Yarra Bend Park makes to the statewide and regional distribution of biogeographic regions. 5 Table 3.1 Contribution of Yarra Bend Park to statewide and regional distribution of IBRA.

Yarra Bend Park has no special areas as described under the Catchment and Land Protection Act. 3.2 Flora - Vegetation Communities 3.2.1 Environmental Responsibilities Vegetation community management is derived from a range of National and State Acts, Regulations and Policies. Those that relate to Yarra Bend Park and the management of the vegetation communities identified within the Park are listed below. For the functions and major elements of each see Appendix 1. 3.2.2 Victorian Legislation Flora and Fauna Guarantee Act 1988 There are 21 vegetation communities listed under the Flora and Fauna Guarantee Act 1988. Yarra Bend Park contains two of these communities: Western (Basalt) Plains Grassland and Rocky Chenopod Scrub. 3.2.3 Biodiversity Broad Vegetation Types (BVTs) There are many different approaches to classifying vegetation. The most up to date vegetation classification system that exists across the whole of Victoria is that of Broad Vegetation Types (BVTs) under which current and pre-European patterns of BVTs have been mapped. BVTs are modelled from 1:250 000 scale land system, climate and other information. They provide a simplified overview of the actual vegetation patterns on the ground. BVTs are assigned on the basis of existing vegetation and other biophysical parameters, such as geology, rainfall, elevation and soil type. There are 32 Broad Vegetation Types across Victoria. Diversity of BVTs within Yarra Bend Park Two Broad Vegetation Types occur within Yarra Bend Park: Plains Grassy Woodland and Valley Grassy Forest. Tables 3.2 and 3.3 summarise the contribution Yarra Bend Park makes to the statewide and regional distribution of each BVT. The Valley Grassy Forest of Yarra Bend Park contribute significantly to the CaLP Regional reserved totals for this BVT. Appendix 2 contains descriptions of these BVTs. Plains Grassy Woodland Fewer than 3% of the Plains Grassy Woodland that existed in 1750 exists in Victoria today. Of this total, only 11% occur in parks and reserves. Yarra Bend Park accounts for approximately 0.6% of the area 6 remaining in parks and reserves in the State, and 23% of the reserved area remaining in the Port Phillip and Westernport CaLP Region. Valley Grassy Forest Approximately 62,1000 hectares of Valley Grassy Forest exists in Victoria today, representing 23.6% of the total estimated to exist in 1750. Yarra Bend Park accounts for 0.8% of the area remaining in parks and reserves in the State, and approximately 100% of the reserved area in the Port Phillip and Westernport CaLP Region.

They consist of one or a number of floristic communities that exist under a common regime of ecological processes within a particular environment at a regional, state or continental scale. Ecological vegetation classes are defined at a qualitative level by both their floristics and structure, and their description includes the ecological processes that characterise them (Woodgate et al 1994). To date, mapping of Ecological Vegetation Classes on Crown land has been carried out in east Gippsland, north east Victoria, Central Highlands and the Box-Ironbark ecosystem of north central Victoria. The Otways, Midlands, southwest Victoria and central Gippsland are currently being mapped. Preliminary Ecological Vegetation Class mapping has also been carried out in the Grampians National Park. Currently EVC mapping has not been carried out in Yarra Bend Park. However, six vegetation communities identified by the Land Conservation Council (LCC) in its Report on the Melbourne Region have been identified in the Park: Valley Forest ; Floodplain Riparian Woodland; Plains Grassland; Rocky Outcrop Shrubland; Floodplain Wetland Complex; and Plains Grassy Woodland (LCC 1991). Appendix 3 contains descriptions of these Vegetation Communities. 7 Remnants of Heathy Woodland vegetation on the Tertiary soils of the hills in the southern side of the Park also exist. A few remnant plants have been discovered in a sheltered gully in the Park, and are thought to be remnants of a gully vegetation community (Yarra Bend Park Trust 1990). The Western (Basalt) Plains Grassland Community listed under the FFG Act occurs in the area nominated as Plains Grassland. The FFG listed Rocky Chenopod Open Scrub Community is found in sections of the area nominated as Rocky Outcrop Shrubland. The other vegetation types are of regional or local significance. The Plains Grassy Woodland community in the Park is significant, as it is one of the most intact representatives of this vegetation community in the region. The majority of the Plains Grassy Woodland elsewhere in the region has been cleared for agriculture or housing (Yarra Bend Park Trust 1990). The Valley Forest Community in the Park is a regionally uncommon community dominated by Yellow Gum. The original LCC report of the Melbourne Region in 1970 drew attention to the regional significance of this community. The Floodplain Wetland Complex community has been reconstructed in this Park. Many of the wetlands and billabongs have been lost from the floodplain of the middle and lower Yarra since the development of the area. The reconstructed wetlands of Yarra Bend Park therefore represent a re-creation of a community that has been greatly depleted. All remnant vegetation at Yarra Bend Park is of at least local significance because Yarra Bend contains the largest block of remnant bush in the inner Melbourne area. The topography and position of the Park, straddling 2 lithologies and watercourses, has meant a range of very different vegetation communities occur in close proximity. This assemblage of communities is of regional significance. 3.2.4 Distribution Figure 3.1 shows the distribution of Broad Vegetation Types within the Park and Figure 3.2 shows the distribution of Vegetation Communities within the Park. 3.2.5 Condition The total area of Yarra Bend Park is 260 ha and approximately 130 ha are covered by indigenous vegetation. Vegetation condition is the extent to which land use and natural events have modified the natural ecology of the vegetation. The following section looks at the extent to which past land use, the presence of infrastructure, the fire history and adjacent land use has modified the vegetation across the Park. Past land use Yarra Bend Park has been subject to a range of past land uses. Most of these, grazing, timber harvesting, quarrying, mining and market gardening are characterised by intensive activity over a long period of time covering the majority of the Park area. Today, the obvious visible effects of this human activity and use have been reduced. Nevertheless, many undesirable effects associated with past land use, including weed invasion and changes to the structure and floristics of native vegetation, persist. Infrastructure A range of recreational facilities and park infrastructure, including buildings, roads, car parks, walking tracks, sports fields, playgrounds and a public golf course has been constructed throughout the Park. As a result, the Park’s native vegetation has been reduced largely to a linear strip that follows the course of the Yarra River and the Merri Creek. The Eastern Freeway and a small residential area that dissect the Park have also fragmented the vegetation. Fire The fire history of the Park prior to European settlement, particularly the use of fire by Aborigines, is unknown. However, from studies undertaken in other parts of Australia we know that Aboriginal groups often used fire to promote fresh growth of grass and to drive game. This probably took place in the area 8 during prehistoric times, and had an influence on the nature and distribution of the plant and animal communities. Following the fires of 1939 that burnt large areas of Victoria, legislation was introduced that compelled managers of public land, including Yarra Bend Park, to prevent and surpress all fires. Resulting modification to the fire regime has led to changes in the vegetation structure and composition. Small deliberately lit fires have occurred at various locations in the Park, which have on occasion adversely affected native vegetation. Park Staff have also undertaken ecological burns across the Park to promote regeneration of indigenous flora and to control weeds (Figures 3.3 and 3.4). Adjacent land use Yarra Bend Park shares boundaries with: Merri Creek (1.79 km). The Merri Creek has a mixture of exotic vegetation and native vegetation planted by various organisations including the Merri Creek Management Committee, along the Council side of the creek. Residential development (2.04 km). Privately owned land with predominantly exotic vegetation. Roads (7.27 km). Yarra River (4.96 km). Industrial and residential areas front the Yarra River along the boundary of the Park. Hospitals (1.7 km). Vegetation condition Table 3.4 summarises the condition of the six Vegetation Communities identified in the Park according to criteria adapted from Duggan, 1992 (Appendix 4).

Those that relate to Yarra Bend Park and the management of the flora species identified within the Park are listed below. For the functions and major elements of each see Appendix 1. 3.3.2 Victorian Legislation Flora and Fauna Guarantee Act 1988 Throughout Victoria, 175 flora species have been listed under the Flora and Fauna Guarantee Act 1988. One of these occurs within Yarra Bend Park: Cullen parvum (Small Scurf-pea) which was re-introduced into the Park in 1995. An Action Statement has been prepared for the management of this species. 9 3.3.3 Biodiversity Diversity Approximately 240 species of indigenous flora have been recorded within Yarra Bend Park (Appendix 5). This equates to approximately 1/10 of the State’s total number of identified flora species. Rarity Yarra Bend Park contains 7 of Victoria’s 1120 threatened flora species, one endangered, three vulnerable and three species suspected of being endangered, vulnerable or rare. In addition, 1 species is rare and 1 species is endangered in Australia. Table 3.5 lists these species, their status (both Victorian and Australian), the number of locations in which they have been recorded in Victoria, the Port Phillip and Westernport CaLP Region and the Park. In addition, the Park contains 117 flora species important in the Melbourne Region (Appendix 6 ). Figure 3.5 illustrates the general distribution of these species in the Park. Endemic species No flora species are endemic to the Park. 3.3.4 Distribution The distribution in Victoria and in the Park of those FFG listed and threatened flora species identified in the Park is given in Appendix 7.

Focus areas are continuous areas of natural vegetation within the Park that have broadly similar physical and biological characteristics and patterns of land management. The distinguishing values of these focus areas and the open parkland, which constitutes the remaining area of the Park, are summarised below with objectives for their long and short term management. The purpose of setting conservation objectives is to establish the desired future condition of a focus area and the open parkland, based on an understanding of its natural values and current condition. This will enable environmental management actions to be prioritised based on a stated vision for the values and condition of the Park. Definitions of the conservation objectives are as follows: Reinstatement: reintroduce natural values that can no longer be found in the park. Preservation: retain the biodiversity and/or the ecosystems at the existing stage of succession. Restoration: improve the condition of existing ecosystems by either returning a park to an approximation of the natural condition or to a known past state. Maintenance: maintain the biodiversity and/or ecosystems while allowing natural processes of regeneration, disturbance and succession to occur. Compatible modification: manage an area to suit proposed uses which are compatible with natural values but are not specifically focusing on the protection of those values. 5.2 Focus area A description Area: 66 ha Exposed edge: 7.5km Revegetation and regeneration sites: 7.46 Ha (49 sites) Vegetation Community Area Condition Wetland Complex 1% revegetation sites Plains Grassy Woodland 19% medium and poor Floodplain Riparian Woodland 50% medium and poor Exotic 30% - Nature based use Past land management friends groups revegetation and regeneration sites - Greenlink Yarra Bend, Men of the Trees, Friends of the Yarra, Friends of Walmer St Bushland and Tree Project geology excursions interpretive garden research passive recreation nature observation grazing 16 farming vegetation cleared site of asylum weed control pest animal control seed collection revegetation mowing controlled burns Main Yarra Trail Yarra Bend Rd informal trails Fairfield Boat House footbridge Dights Falls trails Yarra Boulevard FFG Flora Small Scurf-pea FFG Community Western (Basalt) Plains Grassland Community FFG Fauna Great Egret* Australian Grayling Dwarf Galaxias Striped Legless Lizard Great Egret* Greenshank* Latham’s Snipe* White-throated Needletail* Cattle Egret* Eastern Curlew* Fork Tailed Swift* VROT Flora Short Water Starwort VROT Fauna Nankeen Night Heron Golden Perch Fairlea wetland 2 fairway 3 tee adventure learning asylum terraces Yarra lookout Men of the Trees sites Deep Rock Koori site Willsmere triple wetland Bellbird wetland Current land management Access JAMBA/CAMBA Sites of special significance * nd rd potential habitat of vagrant individuals based on species requirements 17 5.2.1 Focus area A conservation objective Overall conservation objectives: Restoration and Reinstatement 0-5 year objectives 5-10 year objectives Improved condition (less weeds) of previously reinstated wetlands, with naturally regenerating aquatic and semi-aquatic vegetation.

This step is very important in guiding the development of management strategies, actions and resources to address these risks. The environmental risks at Yarra Bend Park are described as events or processes that could cause a loss or reduction in the indigenous flora and fauna present. The risks identified as impacting on the Park’s environmental values are: pest plants; pest animals – rabbits; pest animals – carnivores; domestic animals; habitat competition; soil erosion and compaction; habitat component loss; management activities; dieback; and fire. The risks have been assessed in terms of their extent, trend and impact to environmental values. 6.2 Pest plants The first European settlers found that Australia’s native plants were not the same as the cereals, edible fruits and fibre plants of Europe. It was therefore thought necessary to import these plants and establish colonies in the Australian environment. Other plant species that were of ornamental value were also introduced. In addition to deliberate introductions of pest plants many non-native plant species were successfully naturalised in Australia through accidental introductions via international trade and travel. Under human influence a number of indigenous species have also been naturalised outside their range and are now considered pest plants in their non natural regions. A total of 825 species of exotic plants have been introduced in Victoria. Of this total 576 species have been listed as environmental weeds (Environment Australia 1998). To date greater than 65% of the state carries wholly or predominantly exotic vegetation (Carr 1993). There are approximately 381 non-indigenous plant species recorded within Yarra Bend Park. Of this total, 61 have been identified as warranting a risk assessment due to both their legal status and their impact on the Park’s environmental values. These weed species include 19 species listed as Regionally Controlled weeds under the Catchment and Land Protection Act 1994 (Table 6.1) and a further 42 plants considered to be ‘major environmental weeds’. Table 6.1 Regionally Controlled weeds present in the Park Common name Scientific name Angled Onion Allium triquetrum Artichoke Thistle Cynara cardunculus Blackberry Rubus spp. Boneseed Chrysanthemoides monilifera Boxthorn Lycium ferocissimum Common Thornapple Datura stramonium 24 English Broom Cytisus scoparius Fennel Foeniculum vulgare Flax- leaf Broom Genista linifolia Gorse Ulex europaeus Hawthorn Crataegus monogyna Hemlock Conium maculatum Serrated Tussock Nassella trichotoma Slender thistle Caduus tenuiflorus Spear thistle Cirsium vulgare Stinkwort Dittrichia graveoloens St. John’s Wort Hypercium perforatum Tree of Heaven Ailanthus altissima Wild Watsonia Watsonia bulbillefera Common Thornapple is not currently present in the Park but has been included as it regularly reinvades the Park and is removed once detected. Major environmental weeds are presented in two groups. The first group contains non-grassy weeds and the second group contains grassy weeds (Table 6.2).

Angled Onion is abundant in moist areas of focus areas A and C and is scattered in moist areas of all the remaining focus areas. Spear Thistle is most predominant in recently disturbed areas and revegetation sites in all focus areas (Table 6.3). All the environmental weeds listed in Table 7.1 have been the subject of control programs over the last decade which has limited their spread. Focus area A, the riparian zone in Yarra Bend Park, has the highest level of infestation of regionally controlled weed species (Table 6.3). There are a number of reasons for this: fox and bird activity is high, which facilitates the spread of weeds by seed; soil disturbance from dogs accessing the river and rabbit burrowing and scratching provide opportunities for weed establishment; storm water deposits weed seed carried from adjacent residential and non residential areas; and the soil is high in nutrients. Figures 6.1, 6.2, 6.3 and 6.4 illustrate the distribution of regionally controlled weed species in the Park with the exception of Angled Onion and Spear Thistle due to their wide dispersal. Trend All regionally controlled infestations are decreasing or static except for Angled Onion, which is rapidly increasing in Yarra Bend Park (Table 6.3).

Both these species are abundant in all focus areas (Table 6.4). The major non-grassy environmental weed infestations present in Yarra Bend Park occur largely in the riparian zone (Table 6.4). The reasons for this are similar to the reasons listed above for the occurrence of regionally controlled weeds in this zone. Trend The majority of all major non-grassy environmental weed species are static or decreasing. The remaining major non-grassy environmental weed species are gradually increasing or rapidly increasing in Yarra Bend Park (Table 6.4).

Regionally controlled weed infestations are decreasing in all focus areas. The overall trend of weed invasion, by both grassy and non-grassy environmental weeds, is increasing in all focus areas, with the exception of focus area D, in which environmental grassy weeds are decreasing. 6.2.5 Impact The growth of pest plants can be sufficiently vigorous to reduce or prevent the regeneration or establishment of native plant species, altering the composition and structure of indigenous communities. Modifications to the composition and structure of indigenous vegetation as a result of pest plant invasion can alter the abundance of indigenous fauna, the fire regime, geomorphological process, hydrological cycles and the nutrient content of soil. At a fundemental level, the presence of exotic species in a natural ecosystem, whether they be classed as environmental weeds or not, detracts from the naturalness of that ecosystem by their very presence. It is also difficult, if not impossible, to be sure that an exotic species will not develop weedy tendencies at some future time, as many of our worst environmental weeds were naturalised in the bush for many years before becoming widespread, aggressively invasive pest plants. 28 Pest plant infestations within Yarra Bend Park are predominantly impacting upon the regeneration of native species in the groundlayer, including the FFG listed Small Scurf-pea and the remnant Plains Grassland Community (Appendix 12). In addition, this is modifying the habitat of threatened and JAMBA/CAMBA listed bird species in focus area A and exposing ground dwelling fauna to increased rates of predation. The impact of pest plant infestations on the distribution and abundance of threatened, Regionally Significant and Locally Significant plants is currently unknown. 6.3 Pest animals - Rabbits European rabbits were probably both deliberately and unintentionally released into the wild in Victoria on numerous occasions from the time of first attempted settlement in 1803. However, they were not successfully established until 1859 and by the late 1870s they had become a major agricultural pest (Menkhorst 1996). 6.3.1 Extent Victoria Rabbits occur throughout Victoria from sea level to at least 1 600 m. They occupy most habitats, wherever soils are suitable for burrowing and where there are palatable native grasses and herbs, or where disturbance allows the growth of introduced grasses (Menkhorst 1996). Yarra Bend Park In Yarra Bend Park rabbits are distributed largely in focus areas A and B (Figure 6.5). The results of a spotlight survey undertaken in Yarra Bend Park in 1998/99 indicate that the current rabbit population in the Park is approximately 4.6 individuals per spotlight km (Table 6.6). 6.3.2 Trend General Rabbit populations have an annual cycle. The low numbers at the beginning of the breeding season increase by a factor of 2 - 5 to a peak towards the end of the breeding season (Menkhorst 1996). Rabbit numbers also vary between years in response to climatic conditions, especially the variation in rainfall, parasites, disease, including myxomatosis, and predators (Menkhorst 1996). Rainfall often has a dominant role as it influences both reproductive rate and juvenile survival. As a result, rabbit numbers may increase during favourable seasons and decline during droughts. Because of these fluctuations, long term trends are difficult to identify (Menkhorst 1996). Yarra Bend Park There has been a 40% decrease in the overall mean number of individuals per spotlight km between 1997/98 and 1998/99 in Yarra Bend Park (Table 6.6). The decrease in the overall mean number of individuals per spotlight km can be attributed to the Park’s sustained control program over the last ten years and the dry seasonal conditions the Park has recently experienced. Table 6.6 Results of spotlight counts of rabbits undertaken in the Park Year Average minimum no. of individuals per spotlight km Mean no. of individuals per spotlight km Average maximum no. of individuals per spotlight km 1997/98 2.2 4.1 7.8 1998/99 1.2 2.4 4.6 29 6.3.3 Impact General Rabbits prefer the fresh young growth of palatable plants. Rabbits will also graze preferentially on seedlings of regenerating indigenous plants. This reduces the success of natural regeneration of indigenous flora. Preferential grazing also reduces the regeneration rate of some species compared to others. Seedlings of highly palatable species are more likely to be grazed and this leads to changes in species diversity within vegetation communities and increases the opportunity for weed invasion. Rabbit grazing particularly depletes understorey vegetation. Yarra Bend Park The effect of rabbit grazing on the indigenous vegetation in Yarra Bend Park is largely unknown. However, fencing of the following Regionally and Locally Significant Plants to prevent rabbit grazing and associated soil disturbance in focus area B has drastically improved the recruitment and growth of: Sticky Everlasting, Yellow Gum, Common Flat-pea, Rounded Noon-flower, Common Sunray, Forest Germander, Narrow Leaf Bitter Pea, Bedstraw, Austral Indigo, Trim Greenhood, Pink Fingers, Rough Bedstraw, Maroonhood and Cluster Pomaderris. In addition, the depletion of understorey vegetation due to rabbit grazing has reduced the availability of ground cover for ground dwelling native species which may expose them to increased rates of predation. Ground dwelling native species that may be affected by the reduction in ground cover includes reptiles, amphibians and ground feeding birds such as Brown Quail, Painted Button Quail and Red-Rumped Parrot. 6.4 Pest animals - Carnivores There are two introduced carnivores within Yarra Bend Park, the Red Fox Canis vulpes and the cat Felius catus. Predation of native wildlife by the Red Fox and cat are threatening processes listed under the Flora and Fauna Guarantee Act 1988. Red Fox The Red Fox Canis vulpes was introduced to Australia for recreational hunting in the 1860s, although they were not successfully established in Victoria until the early 1870s. Within 30 years of their initial release foxes were recognised as a pest in some shires of northeast Victoria. Cat Feral populations of cats probably became established in Victoria shortly after initial settlement by Europeans. The spread of cats increased during the 1880s when they were deliberately released in the hope that they would help control plagues of European Rabbits. Both feral and pet cats are now considered to be a serious threat to native wildlife (Menkhorst 1996). 6.4.1 Extent Red fox Foxes occur throughout Victoria, from the semi-arid Lowan Mallee to the tall wet forests of the Eastern Highlands to the Alps where snow persists for several months of the year. They are particularly common throughout pastoral and agricultural land, and in large towns and cities. The fox’s generalist nature, combined with the length of time it has been present in the area, suggests that it is likely to be present throughout the Park. Areas where foxes have been sighted by Park staff include: the Park Depot, Yarra Bend Golf Course, Merri Creek and the Boulevard (Figure 6.6). The nocturnal and elusive nature of the fox makes population and density estimates difficult to determine and often inaccurate. This is further complicated by the cyclical changes in fox densities associated with prey abundance (Saunders et al. 1995). 30 The current fox population and density in Yarra Bend Park is currently unknown however, fox densities of 10 per 100 hectares have been recorded in similar environments (Animal Control Technologies 1996). Cat Cats are widespread in Victoria, being present in all physiographic regions and in most vegetation alliances (Menkhorst 1996). The distribution of cats in Yarra Bend Park has not been investigated. However, resident feral cats have been observed around the Park Depot, the Golf House and Cafe, and Yarra Lookout. It is also assumed that domestic cats enter the Park regularly from adjoing residential areas. 6.4.2 Trend The densities of foxes and cats are expected to be higher in spring and summer following their breeding season than in winter and will also vary in response to food availability and habitat type. 6.4.3 Impact Red fox The fox has long been recognised as a serious threat to populations of native wildlife. Risks foxes pose to native species includes predation, competition and disease transmission. Foxes also contribute to the spread of weeds (Saunders et al.1995). The fox is an opportunistic feeder and is arguably the most adaptable of all carnivores. It is a skilful predator of small animals, particularly terrestrial mammals with mean adult body weights between 3.5g and 5.5 kg, and a scavenger of human refuse and roadside or beach-washed carcasses. Insects and fruit including blackberries are also commonly eaten (Menkhorst 1996). In Victoria foxes eat a wide variety of prey. Over 50 native species have been recorded in the diet of the fox (Mansergh and Marks 1993). However, the rabbit has been identified as the preferred prey species of foxes (Triggs et al. 1984 and Catling 1988). Rabbits may alleviate predation pressure on native species by providing an alternative food supply. However this may facilitate the increase of population densities of predators which, when rabbit numbers decrease, will change to a diet of mainly native species. Fox predation can greatly reduce recruitment in small populations and thus endanger local populations of preferred prey species. Predation may also increase the likelihood of extinction of prey species by increasing the susceptibility of small populations of that species to chance events, eg. fire and flood. Predation can also delay the recovery of populations that are at low density (Kinnear et al. 1984). The impact of fox predation on native fauna in Yarra Bend Park is largely unknown. However, the following categories of native fauna are considered to be at risk from predation: arboreal mammals including Brushtail and Ringtail possums; bird species that spend much of their time at or near the ground nesting and/or feeding including the Tawny Frogmouth, Quails and the FFG listed Night Heron; reptiles; and amphibians. Cat The cat, like the fox, is an efficient and adaptable hunter. They prefer live prey but will scavenge carrion and human food scraps. In Victoria, mammals are the most important prey particularly rabbits and mice. Insects, grass and other herbage are also commonly eaten (Menkhorst 1996). The impact of cat predation on native fauna in Yarra Bend Park is largely unknown. However, the native fauna considered being at risk from fox predation above is also considered to be at risk from cat predation. 31 6.5 Domestic animals 6.5.1 Extent Yarra Bend Park has a number of open recreational areas and a network of trails that are popular for walking dogs. Dogs can be exercised off leads in Yarra Bend Park at Westfield and Fairlea Oval areas in focus area C. Unaccompanied dogs are also occasionally sighted in the Park. 6.5.2 Trend With the number of parks and reserves in inner Melbourne that permit dogs decreasing, it is expected that the number of people who utilise the Park to exercise and walk their dogs will increase. 6.5.3 Impact Dogs in bushland areas of the Park may prey upon or disturb native fauna, particularly birds that spend much of their time at or near the ground nesting and/or feeding including the Tawny Frogmouth, Quails and the FFG listed Night Heron. Dog scent marking (through urine and faeces) also provides a generalised habitat disturbance for native fauna. 6.6 Habitat competition Exotic fauna species including the Common Starling, Common Mynah and honeybee compete with native fauna in Yarra Bend Park for habitat. In addition, a number of non-indigenous native fauna species have been recorded in the Park (Appendices 9 and10). Currently little is known about the the nature and extent of competition by these species with indigenous native fauna in the Park. As a result these species will not be covered in this report. 6.6.1 Extent Australia The Common Starling (Sturnus vulgaris) was successfully introduced in Melbourne, Hobart, Brisbane, Sydney and Adelaide between 1850 and 1880. The species is now common from central Queensland throughout southeastern Australia and Tasmania, as far west as the Eyre Peninsula, South Australia, to fringes of the Nullabor Plain. Birds reaching southern Northern Territory and Western Australia are destroyed (Readers Digest 1997). The Common Mynah (Acridothers tristis) was successfully introduced in Melbourne, Canberra, Sydney and Queensland between 1862 and 1950. Today mynahs are common in most urban centres along the eastern Australian seaboard, but have remained there without spreading far into the rural countryside (Readers Digest 1997). The honeybee (Apis mellifera) was introduced into Australia by European settlers approximately 150 years ago (Doull 1973). Today feral colonies and colonies managed by beekeepers are spread over most of Australia. Yarra Bend Park The Common Starling, Common Mynah and honeybee are resident in the Park. The population and distribution of these species in the Park however, is currently unknown. 6.6.2 Trend The trend in the population of these introduced species is unknown. However, Common Starling and Common Mynah populations are expected to increase following their breeding seasons, August to January and October to March respectively. 32 6.6.3 Impact The Common Starling, Common Mynah and honeybee compete with native fauna in Yarra Bend Park for nesting hollows. As a result, hollow dependent native fauna including, ringtail possums, brushtail possums, bats, parrots, lorikeets, rosellas and kookaburras may be displaced, reducing their breeding success. In addition, introduced honeybees may inhibit the number and behaviour of native pollinators which in turn can disrupt the pollination of plants, reduce seed production, and potentially threaten the long-term survival of native flora (Paton 1993). 6.7 Soil erosion and compaction 6.7.1 Extent Soil erosion and compaction due to recreational traffic, animal activity and changes in hydrology occurs in focus areas A, B, D and E (Figure 6.7). Recreational traffic Recreational traffic (foot and bicycle) has created a number of informal paths through focus areas A, B, D and E. In focus area B informal paths have been created around the Chinese steps as pedestrians find using the steps more arduous than following unsurfaced tracks. In focus areas A, B, D and E mountain bike riders seek out the challenge of cross-country riding especially in steep terrain and along rough paths designed for walkers. This has resulted in the widening of existing walking paths and the creation of new paths through native vegetation. Walkers generally keep to formal paths but will trample vegetation to access views of the wetlands and the Yarra River. This has resulted in the creation of numerous criss-crossing informal paths in focus areas A, B and D. Animal activity Dogs accessing the Yarra River in focus area A have resulted in soil compaction and erosion along the bank of the River. Rabbit burrowing and scratching also contributes to soil erosion along the banks of the Yarra River in focus areas A, B and D. Figure 6.5 illustrates the location of rabbit activity in Yarra Bend Park. Altered hydrology Gully erosion occurs in steep sections of focus areas B, D and E were stormwater enters the Park from the Yarra Boulevard. A number of the gullies to date have been filled and revegetated to prevent further environmental degradation. 6.7.2 Trend Recreational traffic Soil compaction and erosion along informal paths has not been directly quantified. Anecdotal evidence suggests that the number of new trails in the Park is increasing. Attempts have been made to control the spread of tracks by fencing areas and bolting down natural barriers. However, these structures have been subject to vandalism. Park staff have also thinned vegetation in an attempt to decrease pedestrian traffic in important remnant vegetation areas. Animal activity River bank erosion caused by dogs and rabbits has not been directly quantified. Anecdotal evidence suggests that bank erosion is static in undisturbed areas and rapidly increasing in areas where dogs access the river. 33 Altered hydrology Gully erosion caused by storm water has not been directly quantified. However, Park staff have observed gullies increasing in size. To mitigate the effects of gully erosion the Yarra Bend Park Trust have created wetlands designed to reduce the volume and rate of stormwater entering the Park and to capture sediments and chemical pollutants. 6.7.3 Impact Recreational traffic Recreational traffic has lead to the mechanical injury of vegetation, which can impair growth, development and reproductive processes. Further it has altered soil properties including, texture, porosity and moisture content, which can create adverse conditions for plant survival and regeneration. Animal activity Damage to vegetation and soils caused by dog and rabbit activity along the banks of the Yarra River has increased sediment loads entering the River, altering the habitat of river biota such as the FFG listed Australian Grayling through siltation of deep pools and increasing turbidity. Altered hydrology Storm water entering the Yarra River has accelerated the River’s natural processes of scouring and slumping, increasing sediment loads and destabilising riparian vegetation. This in turn alters the habitat of river biota. Stormwater also carries a range of chemical pollutants that pose a risk to aquatic ecosystems. The degradation of native riparian vegetation along Victorian rivers and streams and increase in sediment input into Victorian rivers and streams due to human activities are listed as potentially threatening processes under the Flora and Fauna Guarantee Act 1988. 6.8 Habitat loss Yarra Bend Park provides valuable habitat for a variety of native fauna species. However, habitat destruction or modification through woody weed and wood removal may impact upon the survival of theses species. 6.8.1 Extent Woody weed removal Woody weeds including Blackberry, Boxthorn, Boneseed, Broom, Gorse and Hawthorn are removed or controlled across the Park annually (see section 7.2). Wood removal Fallen tree limbs in areas of the Park that support native vegetation have been removed by members of the public for firewood. In addition deliberate cutting and breaking of tree and shrub limbs has taken place in the Park by: neighbouring residents to improve their view of Park land; survey students to improve the line of sight of survey equipment; and fishers in the Deep Rock Area to gain access to the bank in revegetated areas and to obtain a clear cast to the river. Furthermore Melbourne Water may: reorient trees and branches that have fallen into Yarra River and Merri Creek where they pose a risk to bank stability or impede the flow of water; or as a last resort, remove trees and branches that have fallen into Yarra River and Merri Creek where they pose a risk to bank stability or impede the flow of water. 34 6.8.2 Trend Woody weed removal The control and removal of woody weeds across the Park is ongoing. Wood removal The removal and deliberate cutting and breaking of tree limbs are not common occurrences in the Park. However, the collection of firewood, during winter months, may rise in the future as the popularity of wood fired heating increases in urban areas. Melbourne Water has not removed fallen timber from the Yarra River or Merri Creek in the past 8 years. 6.8.3 Impact Woody weed removal The impact of woody weed removal on native fauna is currently unknown. However, woody weed removal can result in habitat loss for shrub/middlestorey nesting species such as wrens and indigenous fauna that feed on the fruit and seeds produced by these species. To reduce the risks associated with this activity Park staff remove woody weed species in stages to allow for regeneration of indigenous habitat. Wood removal The removal of fallen timber reduces the available habitat for small ground dwelling mammals, reptiles and invertebrates. It also removes obstructions to soil erosion. Mechanical injury of vegetation due to the deliberate cutting and breaking of tree limbs can impair growth, development and reproductive processes. The reorientation and removal of trees and limbs from the Yarra River and Merri Creek may alter the habitat of aquatic biota including the Murray Cod (FFG listed), River Blackfish, Broad Finned Galaxias, Flat Headed Gudgeon and Tupong. 6.9 Management activities A range of park management activities are undertaken across the Park to maintain and improve recreational and environmental values. However, these management activities, in particular the application of herbicides and mowing, can have negative impacts upon the Park’s environmental values. 6.9.1 Extent Herbicide use A range of herbicides including schedule 5, 6 and 7 hebicides are regularly used across Yarra Bend Park as part of infrastructure maintenance, weed control, environmental value protection and revegetation projects. Mowing Open recreational areas of Yarra Bend Park are regularly mown as part of infrastructure maintenance. 6.9.2 Trend Over the past three years the level of herbicide use in the Park has remained constant and the area of open recreational areas mown has slightly decreased. 6.9.3 Impact Herbicide use The impact of herbicide use on Park environmental values is currently unknown. However, herbicide use may impact upon native flora and fauna by: 35 non target spraying of indigenous flora; infiltrating soil affecting invertebrates and soil microorganisms; and infiltrating wetlands affecting birds, amphibians and fish. Mowing The mowing of open recreational areas impedes the regeneration of indigenous grasses by not allowing them to set seed. Anecdotal evidence suggests that once open recreational areas containing indigenous grasses are removed from mowing indigenous grasses regenerate strongly. 6.10 Dieback Dieback is the protracted decline in the health and vigour of trees often ending in their death (Heatwole and Lowman 1986). The symptoms associated with dieback include: decline and thinning of the primary crown; death of minor branches or of major limbs; epicormic growth from the trunk or main branches; and tree death. A range of complex factors may be associated with dieback including: fungal attack from Armillaria luteobubalina and Phytophthora cinnamomi; unbalanced populations of fauna including birds, insects and possums; soil compaction and changes to soil hydrology resulting in waterlogging; changes to vegetation structure resulting in increased exposure; and natural environmental events (lightning, wind, hail, frost) and extremes (drought, flooding and fire). 6.10.1 Extent Victoria Dry sclerophyll forests in coastal East Gippsland and South Gippsland, in the Dandenong Ranges near Melbourne, in west-central Victoria, and in western Victoria are most affected by dieback (Neumann et al. 1981) Yarra Bend Park The extent of Dieback in Yarra Bend Park has not been fully investigated. However, dieback of mature individuals of eucalypt species including Yellow Box (Eucalyptus melliodora), Yellow Gum (E. leucoxylon) and River Red Gum (E. camaldulensis) have been recorded within the Valley Forest Community in focus areas B and D. 6.10.2 Trend Reports by Norton (1886) and MacPherson (1885) indicate that over 100 years ago, dieback was affecting Australian forests. Since that time the frequency, severity and extent of dieback episodes have increased (Kasel 1999). The trend in the frequency, severity and extent of dieback episodes in Yarra Bend Park is unknown. 6.10.3 Impact Small localised pockets of dieback of mature individuals of eucalypts species are a natural occurrence and provide opportunities for species recruitment. However, losses of large mature stands change the structure and composition of the vegetation and reduce the habitat of dependent native fauna. The impact of dieback on indigenous flora and fauna in Yarra Bend Park is unknown. 36 6.11 Fire Fire has been prevalent in the Australian landscape for thousands of years. Australia’s unique flora and fauna have evolved with fire and are therefore adapted to and are largely dependent on fire for their continued existence and development. 6.11.1 Extent Victoria Southeastern Australia is one of the most fire-prone areas in the world due to its hot and dry climate. Wildfires mostly occur in the summer months when ignition sources and fuel are available. In addition, controlled and ecological burns are carried out throughout the state. Controlled burns are carried out as a preventative measure, for the protection of human lives, property, natural and cultural assets, and to reduce the severity of wildfires when they do occur. Ecological burns are carried out to alter habitat structure and plant and animal composition to achieve desired biodiversity outcomes. Yarra Bend Park Thirteen wildfires totalling 7.89 ha have occurred in Yarra Bend Park between 1985 and 1998 across focus areas A, B, D and E in the Valley Forest Community (Table 6.7) (Figure 3.3). Table 6.7 Distribution and area of wildfires over a thirteen year period in the Park.

Table 6.8 Distribution and area of ecological burns over a thirteen year period in the Park. Year Area (ha) Focus area 1995 0.53 A 1996 0.27 A 1995 0.13 A 1997 0.06 A 1997 0.28 A 1996 0.23 A 1995 0.31 A 1991 0.45 A 1994 2.2 B 1997 0.22 B 37 1997 0.81 D 1996 1.37 D 1989 0.47 D 1992 0.29 D 1988 1.1 D 1995 0.08 E 1995 0.06 E 6.11.2 Trend Victoria Major fires occur in grasslands every one to five years across the state. In contrast, infrequent fires are associated with the wetter rainforest and arid regions (NRE and CFA 1999). In addition, devastating wildfires affected large areas of the state in 1939 and 1983. Yarra Bend Park The number of wildfires deliberately lit or inadvertently caused by park visitors has increased annually between 1985 and 1998. With an increasing understanding of the fire regimes required to maintain the vigour and diversity of the Park’s vegetation communities the number of ecological burns carried out annually in the Park is expected to rise. 6.11.3 Impact General Wildfire, fire suppression operations and inappropriate fire regimes can lead to the direct loss of native flora and fauna or a reduction in their biodiversity. Yarra Bend Park The frequency, intensity, area and distribution of wildfires and ecological burns between 1985 and 1998 in the Park have been such that negative impacts on the Park’s values have been minimal. However, wildfires and ecological burns may present the following threats to indigenous flora and fauna in the Park: loss of hollows for hollow dependent species such as Brushtail possums, Kookaburras, Lorikeets, parrots, Rosellas and ducks; increased opportunities for weed invasion; loss of indigenous flora, particularly in revegetation areas where the indigenous flora has not developed the capacity to regenerate, either vegetatively or from seed; and loss of habitat for ground and middle storey feeding and nesting birds. In addition, fire regimes that would maintain and improve the condition of the Park’s vegetation communities have not being achieved Park wide, which may reduce the diversity of the Park’s flora and its dependent fauna. 6.12 Priority risk management issues for Yarra Bend Park The following prioritised list is based on the risk posed by each of the threatening processes present in the Park. The order reflects the extent, trend and impact of each process affecting the key environmental values of the Park. Pest plants Pest animals – rabbits Soil erosion and compaction Pest animals – carnivores 38 Fire Habitat component loss Domestic animals Habitat competition Dieback Management activities The risks that pose a threat to environmental values in each of the focus areas are summarised below in Table 6.9.

The strategies and actions complement the Yarra Bend Park Strategy Plan (1999) and are consistent with the Management Services Specifications. A total of 21 strategies and 177 actions are to be implemented through the Environmental Management Program over a two year period. Operating costs for each action are provided where known and incorporate the materials, contractors and consultants.

JAMBA and CAMBA define migratory birds as those birds that migrate between Australia and Japan and Australia and China. Around half of the species listed are shorebirds, however seabirds, such as terns, shearwaters, boobies and frigatebirds, together with some species of swallow and wagtail are also on the lists. Migratory birds are threatened by the loss or alteration of their habitat and by hunting. The wetlands these birds visit on their migration are under pressure from human impacts such as clearing for agriculture and grazing, runoff from fertiliser and urban and industrial waste. Under JAMBA and CAMBA, the Governments of Australia, Japan and the People’s Republic of China have agreed to protect migratory birds and their important habitats by: preserving and enhancing the important habitats used by migratory birds listed in the agreements; encouraging joint research programs and sharing the information gained; establishing sanctuaries and other facilities for the management and protection of migratory birds and their habitats; preventing damage to migratory birds and their habitats, and encouraging their conservation. There are around 80 species listed in both agreements, 59 of which are common to both. JAMBA includes two additional annexes that list those birds in danger of extinction in Australia and Japan (NRE 1998a). Commonwealth Government Legislation Australian Heritage Commission Act 1975 (Register of the National Estate) The Register of the National Estate is a national inventory of places deemed to be components of the natural and cultural environment of Australia that have aesthetic, historic, scientific or social significance or other special value for future generations as well as for the present community. The Register is compiled and administered by the Australian Heritage Commission under the Australian Heritage Commission Act 1975. The purposes of the Register are to (among other things): alert and educate Australians about significant places and the natural and cultural history of the country; and improve decision-making including Commonwealth decisions and actions. The Register does not impart any legal obligation on the land manager concerned to manage that item in any particular manner. The Australian Heritage Commission does not assume management responsibility for registered places (NRE 1998a). 57 National Policies and Initiatives Interim Biogeographic Regionalisation of Australia The Interim Biogeographic Regionalisation of Australia is a national approach for the classification of ecosystems. Biogeographic regions capture the patterns of ecological characteristics in the landscape, including climate, lithology/geology, landform, vegetation, fauna and land use. The IBRA was developed, by the Australian Nature Conservation Agency, as a framework for establishing the National Reserve System. It is used to identify gaps in the existing protected area network and to establish priorities for land purchase to fill those gaps. The Australian and New Zealand Environment and Conservation Council (ANZECC) endorsed the IBRA in November 1995. The IBRA identifies eighty bioregions across Australia, eleven of which occur in Victoria with eight of these shared with adjacent states. The broad scale that is appropriate for national purposes does not adequately discriminate between areas that are meaningful at the statewide scale and further refinement has delineated 21 Victorian bioregions (NRE 1998a). Victorian Legislation Flora and Fauna Guarantee Act 1988 This Act provides the basic legal powers and the management systems needed for the protection of the State’s native flora and fauna, and that taxa, except for those specified, survive, flourish and retain their potential for evolutionary development in the wild (on all land). This includes the conservation of communities; the management of threatening processes; sustainable use; and the maintenance of genetic diversity. The Act provides for: the establishment of the Scientific Advisory Committee to advise the Minister; the listing of taxa and communities of flora and fauna which are threatened; listing of potentially threatening processes; Action Statements and Critical Habitats (NRE 1998a). Catchment and Land Protection Act 1994 This Act sets up a framework for the integrated management and protection of catchments, establishes processes to encourage and support community participation in the management of land and water resources, and provides for a system of controls on noxious weeds and pest animals. The Act also establishes the Victorian Catchment and Land Protection Council, and the Pest Animal Advisory Committee. It also provides for developing Regional Catchment Strategies, Special Area Plans, Land Management Notices, and includes enforcement provisions. From 1 July 1997, Catchment Management Authorities (CMAs) came into effect for 9 existing rural Catchment and Land Protection Regions. These bodies combine the roles of: Catchment and Land Protection Boards; River Management Authorities; salinity implementation groups; water quality groups; and sustainable regional development committees (NRE 1998a). 58 Appendix 2 Broad Vegetation Types at Yarra Bend Park Plains Grassy Woodland Plains Grassy Woodland BVTs occupy fertile plains under low rainfall regimes of 400-700 mm per annum. The original geologies of the plains vary, with the Western Volcanic Plains being basalts, the Sale Plains being outwash clays and the Northern Plains being riverine silts and clays. Other minor components include sites with Tertiary outwash deposits (Dundas Tablelands) colluvial deposits localised in topography associated with valleys. These BVTs are characterised by very low density cover of trees such as River Red Gum Eucalyptus camaldulensis on basalt and siltstone derived soils, Forest Redgum Eucalyptus teretecornis on gravelclay outwash, Yellow Box Eucalyptus melliodora and White Box Eucalyptus albens on riverine silts and clays. Mixtures of Black Box Eucalyptus largiflorens, Yellow Gum Eucalyptus leucoxylon and Buloke Allocasuarina luehmanii are characteristic in the Wimmera north of the Little Desert. The most usual shrubs are Lightwood Acacia implexa, tree-form Silver Banksia Banksia marginata, Golden Wattle Acacia pycnantha, Cranberry Heath Astroloma humifusum and a ground layer dominated by perennial grasses, particularly Wallaby Grasses Danthonia spp., Spear Grasses Stipa spp., Kangaroo Grass Themeda triandra, Cane Wire Grass Aristida ramosa, herbs such as Scaly Buttons Leptorhynchos squamatus, Kidney weed Dichondra repens, Solenogynes Solenogyne spp., Fireweed Senecio quadriedentatus, Austral Bear’s Ear Cymbonotus preissianus and perrenial geophytes especially orchids and lilies. This BVT is characterised by extensive tracts of land with this vegetation. The dominant ecological vegetation class represented in this BVT varies according to biogeographic zone and parent geology: on the Western Volcanic Plains heavy clay basalts soils the ecological vegetation class is Western Plains Grassy Woodland; on the Sale Plains outwash clays the dominant ecological vegetation class is Gippsland Plains Grassy Woodland; and on the Northern Plains with its riverine silts and clays, the smaller areas of Wetland and Grasslands. There are however smaller outliers of fertile geology that support this vegetation BVT such as the granodiorites around Mansfield and the limestones of Buchan and Murrindal area. Valley Grassy Forests Valley Grassy Forests BVTs occur on the lower slopes of river valleys as they exit the foothills of the Great Divide, especially but not exclusively in northern Victoria. The rainfall is between 650-750 mm per annum and the soils are fertile silts and clay loams derived from old river flats or fertile geologies such as granodiorites. The BVT is dominated by a medium forest of Yellow Box Eucalyptus melliodora, Gippsland Grey Box Eucalyptus bosistoana, Southern Blue Gum Eucalyptus globulus and Candlebark Eucalyptus rubida, that has an open, nearly shrub free understorey and a ground layer that is characterised by an abundance and diversity of grasses, particularly Wallaby Grasses such as Slender Wallaby Grass Danthonia pilosa, Striped Wallaby Grass Danthonia racemosa, Weeping grass Microleana stipoides, and tussock grasses such as Soft Tussock-grass Poa morisi, Common Tussock-grass Poa labillardierei, herbs and geophytes such as lilies and orchids. The most usual ecological vegetation class in this BVT is Valley Grassy Forest and this may have smaller areas of Riparian Forest, Riparian Swampy Woodland associated with drainage lines and Heathy Dry Forest or Grassy Dry Forest on the adjacent slopes of river valleys. 59 Appendix 3 Bend Park LCC descriptions of Vegetation Communities recorded in Yarra Valley forest The overstorey is dominated by a mixture of Red Box (Eucaluptus polyanthemos), Red Stringybark (E. macrorhncha), Long-leaf Box (E. goniocalyx) and Yellow Box (E. melliodora).The shrub layer is sparse comprising Burgan (Kunzea ericoides), Cherry Ballart (Exocarpos cupressiformis), Black wattle (Acacia mearnsii), Sweet Bursaria (Bursaria spinosa) and Common Cassinia. A rish array of native grasses and herbs occur in the groundlayer. Weeping Grass, Kangaroo Grass (Themeda triandra), Grey Tussockgrass and Silvertop Wallaby-grass (Chionochloa pallida) are common (LCC 1991). Floodplain riparian woodland River Red Gum (E. camaldulensis) forms a tall, woodland canopy over a medium to tall shrub layer including Silver Wattle (A. dealbata), Tree Violet (Hymenanthera dentata), River Bottlebrush (Callistemon sieberi), and River Tea-tree (Leptospermum obovatum). The ground layer features common tussockgrass (Poa labillardieri) on the drier, elevated banks, with club-sedges (Isolepis spp.), rushes (Juncus spp.), common reed, and Water-ribbons (Triglochin procera) occupying the saturated or inundated soils at the water’s edge (LCC 1991). Plains grassland Dominated by Kangaroo Grass (Themeda triandra), plains grassland is a tussock grassland with a scattered and depleted distribution, mostly on fertile, basalt-derived soils. In addition to Kangaroo Grass, characteristic species include Pink Bindweed (Convolvulus erubescens), Common Bog-sedge (Schoenus apogon), Lemon Beauty-heads (Calocephalus citreus), Sheep’s Burr (Acaena echinata) and common Wallaby Grass (Danthonia caespitosa) (LCC 1991). Rocky outcrop shrubland The overstorey is dominated by stunted Yellow Gum (E. leucoxylon spp.) and Grey Box (E.microcarpa). The understorey is tall and shrubby and features Gold-dust Wattle (A. acinacea), Golden Wattle (A.pycnantha), Shiny Cassinia (Cassinia longifolia) and Fragrant Saltbush (Rhagodia parabolica). The understorey also features a number of smaller shrubs including (Einadia hastata)and (Carpobrotus modestus) (LCC 1991). Floodplain Wetland Complex Deep, permanent billabongs typically have a dense fringe of vegetation, but, due to their greater depth of water in the centre, tend to include open water. This open water may support a carpet of Water-duckweed (Lemna spp.) and/or Azolla (Azolla spp.). The fringing vegetation includes Tall Spike-sedge (Eleocharis sphacelata), Milfoils (Myriophylla spp.), Water-ribbons (Triglochin procera), Cumbungi (Typha orientalis), common reed and rushes. Shallow, seasonal billabongs that dry out in summer commonly support a herbfield including common Spike Sedge, Slender Knot-weed (Persicaria decipiens), Common Brown-grass (Agrostis avenacea), and Sneezeweeds (Centipeda spp.). Floodplain wet flats occur on river flats where the river-side levee-banks retain seepage or overflow. Characteristic vegetation include common reed, Marsh Club-sedge (Bolboschoenus medianus), Tassel Sedge (Carex fascicularis), Tall Sedge, Large Bindweed (Calystegia sepium) and common Tussockgrass (LCC 1991). Plains grassy woodland The most common components of this community are the grassy woodlands dominated by River Red Gum (E. camaldulensis) (LCC 1991). 60 Heathy woodland A low woodland of Narrow-leaf Peppermint (E. radiata), Mealy Stringybark (E. cinerea), and Messmate (E. obliqua) overtops a shrublayer including Hairpin Banksia (Banksia spinulosa var. cunninghamii), Bushy Hakea, Furze Hakea (Hakea ulicina), Prickly Tea-tree (Leptospermum continentale), Pink Swampheath (Epacris spp.). The ground layer includes: Spread Rope Rush \, Hair-sedge, Square Twig-sedge, Pouch Coral-fern (LCC 1991). 61 Appendix 4 Vegetation condition assessment Physical disturbance Weed intrusion (impact of alien flora) Ecological balance Diversity of indigenous flora Rating nil nil to moderate reasonable to good moderate good 0 - moderate moderate reasonable moderate to significantly reduced medium 0 - severe moderate to heavy poor significantly reduced poor 0 - severe very heavy drastically out of balance low to absent very poor 62 Appendix 5 Flora of Yarra Bend Park Scientific name Common name Family name Acacia acinacea s.l.

R Species which are rare in Australia but which are not currently considered endangered or vulnerable. Such species may be represented by a relatively large population in very restricted areas or by smaller populations spread over a wider range. 80 Statewide distribution of FFG flora species and communities Cullen Parvum Small Scurf-pea The Action Statement prepared for the Small Scurf-pea indicates although the species was considerably more widespread in the past, there are now only eight known populations of the species in the north and south of central Victoria excluding Yarra Bend Park. It is found in grassland and grassy woodland which is subject to irregular flooding on alluvial and basalt soils. The main stronghold of the species is in the Barmah State Park and State Forest. Within the Port Phillip CaLP region the species only occurs in Yarra Bend Park, along a road reserve between Shelford and Mt Mercer and a single plant in Deer Park. These three locations in the Port Phillip CaLP region therefore play a vital role in the conservation of this species. Western (Basalt) Plains Grassland Community The Action Statement prepared for this community indicates that Western (Basalt) Plains Grassland occurs within a 23 000 square kilometre area of flat to undulating basalt plains in Victoria. This area is bounded by Melbourne to the east, Hamilton to the west, Beaufort to the north and Colac to the south. Very little of the community remains intact. In 1986 only 3000 hectares supported the community now listed under the Flora and Fauna Guarantee Act 1988. Typically these sites are isolated remnants surrounded by introduced vegetation. The land tenure of the remnants on basalt-derived soils was: private land 46%, roadside 28%, unreserved Crown Land 10%, disused rail reserves 7%, rail reserves 6%, biological reserves 2% and cemeteries <1%. Rocky Chenopod Open Scrub Community No Action statement has been prepared for this community.The distribution of this community in Victoria is unknown. 81 Distribution of FFG flora species and communities within the Park Scientific name Common name Characteristics/Vegetation types Cullen parvum Small Scurf-pea The top growth dies back over summer and sprouts again in spring Occurs at reconstructed wetland in the Park The population has increased from the original plants transplanted.

Western (Basalt) Plains Grassland Community Protect existing remnants. Improve the quality of remnants. Prevent damaging activities and use fire and herbicides as management tools. 82 Statewide distribution of threatened flora species Callitriche brachycarpa Short Water Starwort The Short Water Starwort only occurs in six locations across the state. It occurs in three locations on the Otway Coast and in three locations in the Port Phillip CaLP region. In the Port Phillip CaLP region the species occurs in Yarra Bend Park and in two sites south of the Kinglake National Park. These three locations in the Port Phillip CaLP region therefore play a vital role in the conservation of this species. Agrostis aemula var. setifolia Gilgai Blown Grass The Gilgai Blown Grass only occurs in a limited number of locations across the state. These locations are from Ballarat to the Little Dessert National Park in the west of the state, north of the Melbourne metropolitan area and on the east coast. Within the Port Phillip CaLP region the species is only found in Yarra Bend Park and around Plenty Gorge. These locations in the Port Phillip CaLP region therefore play a vital role in the conservation of this species. Bolboschoenus fluviatilis Tall Club-sedge The Tall Club-sedge only occurs in approximately eight locations across the state. These locations include the Victorian Volcanic Plains in the west, the Midlands in central Victoria and East Gippsland (Walsh and Entwisle 1994a). Within the Port Phillip CaLP region the species is only found in two locations including Yarra Bend Park. These locations in the Port Phillip CaLP region therefore play a vital role in the conservation of this species. Agrostis avenacea var. perennis Wetland Blown Grass Specimens of Wetland Blown Grass have been recorded in Victoria from near the Yarra River, from Wando Vale near Casterton and from Snowy Creek, a tributary of the upper Overns River, near Freeburgh. However, further studies may show the formal distinction given to var. perennis from the widespread Common Blown-grass (Agrostis avenacea) may be unnecessary, as the distinctive features of var. perennis may be as much due to ecological as genetic factors (Walsh and Entwisle 1994a).The distribution of the species in the Port Phillip CaLP region is unknown. Cullen parvum See previous description for this species Small Scurf-pea Eucalyptus leucoxylon ssp. connata Yellow Gum The distribution of this non-glaucous form of E. leucoxylon is limited to two locations within the Port Phillip CaLP region, the Brisbane Ranges and northeastern metropolitan Melbourne including Yarra Bend Park (Walsh and Entwisle 1994b). These two locations in the Port Phillip CaLP region therefore play a vital role in the conservation of this species. Poa labillardieri (Basalt Plains form) Blue Prickly Tussock Grass The distribution of this species in Victoria is unknown. 83 Distribution of threatened flora in Yarra Bend Park Scientific name Common name Characteristics/vegetation types Agrostis aemula var. setifolia Gilgai Blown Grass Location and identification to be confirmed Requires seasonally wet soils.

The species has been widely sighted across the Port Phillip CaLP region. Lathimus discolor Swift Parrot The Recommendations for Listing of the Swift Parrot indicates that, although once quite widely spread throughout Victoria, this species appears to now be primarily located in open eucalypt woodlands occurring in southern and central Victoria. The species has been sighted widely across the Port Phillip CaLP region. Xanthomyza phrygia Regent Honeyeater The Action Statement for Regent Honeyeater indicates that it occurs mainly in dry open forest and woodland in areas of low to moderate relief on the inland slopes of the Great Dividing Range. It also indicates that they occur frequently in broad valleys extending into the ranges and occasionally visit the east Gippsland coast. The species has been sighted across the Port Phillip region. Prototroctes maraena Australian Grayling The Australian Grayling is located in limited numbers in river systems along the coastline of Victoria and the interior of east Gippsland and the Melbourne metropolitan area. Within the Port Phillip CaLP region the species has been recorded in the Yarra, Marribyrnong and Bunyip rivers and the Cardinia Creek. Yarra Bend Park therefore plays an important role in the conservation of this species. Ninox connivens Barking Owl Recorded sightings of the Barking Owl have occurred throughout the state with particular concentrations around the Melbourne metropolitan area and the Murray River south of Kerang. The species has been widely sighted across the Port Phillip CaLP region. Ninox strenua Powerful Owl A draft Action Statement for the Powerful Owl is currently being prepared. The Action Statement indicates that the distribution of the species is fairly widespread across Victoria with the exception of the far north west of the state. Within the Port Phillip CaLP region the species has been sighted in the northeast and south east of the region. Delma impar Striped Legless Lizard The Action Statement for the Striped Legless Lizard states that the distribution and abundance of the Striped Legless Lizard are poorly documented as the species is rarely seen. In Victoria the most recent sightings of the species have been in Port Phillip CaLP region in west and north of the region and in the Western District. The Action Statement states that recent studies have found the Striped Legless Lizard generally occurs in perennial lowland tussock grasslands with year-round cover. 93 Distribution of FFG fauna species within the Park Scientific name Common name Habitat & behaviour Focus area Birds Xanthomyza phrygia Ardea alba Lathimus discolor Ninox connivens Ninox strenua Regent Honeyeater Great Egret Swift Parrot Barking Owl Powerful Owl Last observed in the Park in 1996 (juvenile bird associating with wattle birds) for duration of 3 weeks. Before this observation it is regarded as an occasional visitor and has been observed to breed in the Park. Feeds in the shallows of watercourses and water bodies. Nests on the ground. Occasional visitor to the Park. Feeds in foliage of predominantly eucalypts. Nests in hollows. Occasional visitor in Autumn and Winter. Several reports of a Barking Owl calling were obtained from near Alphington Boathouse 1988/1989 Beardsell, C. (1997). They have a large permanent territory. Prey is seized from the ground and the air. Yarra Bend Park would not have suitable habitat to maintain a pair of Barking Owls. The record of Barking Owls would be of a dispersing individual. A Powerful Owl was recorded calling near Studley Park Boathouse in April 1993 (Beardsell 1997). The Yarra River provides a habitat link to the suburbs and juvenile birds dispersing from the foothills may pass through Yarra Bend Park. Powerful Owls occupy large permanent territories. Yarra Bend Park would not have suitable habitat to maintain a pair of Powerful Owls. The most recent record of this species is 1975 from the Dights Falls area of the Park. The grid reference of the record is on the opposite side of the Yarra to the Park but in the river flats. If was decide to include the Striped Legless lizard as extant in the Park as the record means that the lizard is not extinct in the area. The action statement states that this species is generally found in perennial lowland tussock grasslands with year-round cover. The major type of grassland it occurs in is the Western (Basalt) Plains Grassland. Breeds in coastal estuaries and moves up the Yarra to feed in fresh water. Movement is affected by Dights Falls. Anecdotal evidence suggests that a minor increase in fish numbers upstream of Dights Falls has occurred since the construction of the fish ladder.

The Port Phillip CaLP region has recorded approximately one third of all sightings across the state. Accipiter novaehollandiae Grey Goshawk Recorded sightings of the Grey Goshawk are scattered throughout the state with particular concentrations around the Otways, Lakes Entrance and the Melbourne metropolitan area. The species has been widely sighted across the Port Phillip CaLP region. Falco subniger Black Falcon The Black Falcon occurs widely across the state with fewer sightings in the east. The species has been widely sighted across the Port Phillip CaLP region. Nycticorax caledonicus Nankeen Night Heron Recorded sightings of the Nankeen Night Heron are scattered throughout the state with particular concentrations along the Murray River, the Melbourne metropolitan area and east of Melbourne. There have been a number of sightings in the Port Phillip CaLP region. Macquaria amgigua Golden Perch The Golden Perch occurs in a number of locations stretching from the Murray River in central Victoria to south of the Grampians National Park in the west of the state. The species occurs in only two other spots in the state both within the Port Phillip CaLP region and one being Yarra Bend Park. Macquaria novemaculeata Australian Bass The Australian Bass predominantly occurs in the far east of the state. The species occurs in only two other spots in the state both within the Port Phillip CaLP region and one being Yarra Bend Park. 95 Distribution of threatened fauna in Yarra Bend Park Scientific name Common name Habitat and behaviour Myotis macropous Southern Myotis Detected with a bat detector near Heidelberg Rd and Merri Creek. A roost was located under the bridge in 1992. Feeds over water on aquatic invertebrates. Roosts range from tree hollows, caves and dense vegetation. Sedentary birds which wander in search of new territory and nest high in tree forks. Yarra Bend Park does not provide suitable habitat, as they prefer dense stands of trees. They have been observed in the Park on six occasions. These observations would be of birds searching for new territory. Requires high vantage points for perching and searching for prey. Uses nests of other large birds. Nomadic and observed less than six times in Yarra Bend Park. Nankeen Night Herons roost on riparian vegetation overhanging water during the day and feed on grassland areas and hunt for fish, insects and amphibians at night. Individual herons have been observed roosting at various places along the Yarra River and Merri Creek. Small colonies of birds have been observed roosting near Kanes Bridge. Not an indigenous fish of the Yarra River. It occurs in the Murray Darling River system. Not an indigenous fish of the Yarra River. It occurs north of Wilsons Promontory NP along the east coast of Australia (Philip 1983).

Manage all such sites to retain the number of the key eucalypt species and to increase the number of mature trees of these species. Maintain suitable habitat that is not disturbed and has good tussock cover. Undertake ecological burns in autumn when soil is dry and soil cracks are open for the lizard to take refuge. Burning should be carried out in a patch work mosaic with each area burnt at a frequency of at least five years to allow good tussock cover to develop. Control weeds invading the grassland especially Chilean Needle-grass.
