Regionally Significant Weeds In the Southern Rivers CMA region Common Distribution, Name status and trend1 Lantana Extensive becoming more widespread and common in the northern part of region; rare and isolated south of Ulladulla. Lantana must be stopped in the area south of Ulladulla. Serrated Tussock Widespread across the region, particularly tablelands, though in many areas it remains absent or sparse. Still spreading rapidly. Found primarily along transport corridors in the Kiama and Shellharbour LGAs. More widespread in the Wollongong LGA. Not present south of Kiama on the coast or the tablelands at this stage. Spreading. Widespread throughout the region. Common weed of roadsides, unimproved grazing land. And disturbed bushland. Persistent patches are in hard‐to‐manage areas. Coolatai Grass Blackberry Priority sites Containment strategy Key actions National, State, regional or local strategies2 Southern containment zone lies to the south of the boundary with ESC. Shoalhaven buffer zone lies to the south of Ulladulla. Lower priority–Illawarra and Shoalhaven land management zone lies to the north of Ulladulla. Clean country and small new infestations. Larger infestations must not be neglected and land managers may need support. Eradicate south of the containment line; strategically reduce in the buffer zone, Protect priority sites in land management zone. Prevent sale. Staged eradication/control programs in the containment and buffer zones.. Protect priority sites in land management zone. Promote best practice management. Facilitate biological control.

GRASSY WEEDS THREAT ABATEMENT PLAN (TAP). High risk pathways in the Kiama and Shellharbour LGAs (ie transport corridors). Establish containment line on Shellharbour / Wollongong boundary. Prevent spread south and west by establishing containment zones within the Wollongong LGA and destroying all infestations in adjoining LGAs. Search and destroy all infestations outside the Wollongong LGA. Establish containment lines on the Wollongong LGA boundary. GRASSY WEEDS TAP According to local priorities. Keep clean areas clean. Protect key threatened species and EECs. Concentrate efforts to clean areas. Staged programs progressively control larger patches. Education and awareness programs ST&SCNPC plan concluded Dec 2007.

Eradicate small infestations. Consolidate previous control. Staged programs on larger infestations. ST&SCNPC plan concluded Dec 2007. Gorse Limited distribution in the south; more common in the north. All areas if found. Search and destroy all infestations. Target high risk pathways to prevent / limit spread. Fireweed Widespread across the coastal plain, though in some areas, it still remains absent or sparse. Spreading rapidly, All willows are widespread, associated mostly with rivers. Seedling willows on gravel beds. Isolated populations at Bombala, Bega and in the Wollongong area. New infestations continue to be found. Marginal population at Braidwood,. Large clean areas according to local priorities. EECs such as Themeda headlands Control emerging infestations. Target high risk pathways to prevent / limit spread. Prevent sale. Staged eradication programs of smaller infestations. Facilitate biological control. Reduce marginal infestations. Promote best practice management in core infestations. Extension program. Search and destroy all infestations. Promote best practice management. Control on road verges and along riparian corridors. Search and control emerging populations.

It is more common and in greater density in the northern Shoalhaven and Illawarra regions. Limited distribution south of Sussex Inlet. Control programs are progressively reducing it. Emerging as a difficult weed in Illawarra and lower Shoalhaven. Recently found at Bega. All areas south of the national containment line at Sussex Inlet. Protect areas according to TAP priorities north of Sussex Inlet. Staged programs outside of TAP sites. In the containment zone eradicate all infestations. Consolidate and expand previous control programs to the north of the containment line. Eradicate all infestations south of Sussex Inlet. Search and destroy rare and isolated infestations to the north. Reduce marginal infestations. Contain core sites and establish buffer zones to prevent further spread. ST&SCNPC plan concludes June 2011. BITOU TAP. National Strategy for bitou bush and boneseed. Clean country and small isolated/new infestations. Reduce spread by promoting better stock and produce movement practices. Control small infestations. Staged programs on larger infestations. Restrict expansion. ST&SCNPC plan concluded March 2007.
