Next steps
Aim
Provide information on the floodplain
and coastal ecosystems and their
services at multiple scales and taking
into account multiple pressures
Geographic Region / Location
Northern Australia – east of Darwin
Coastal biogeographic region
Alligator Rivers – 28 000 km2
Catchments of three rivers
Kakadu National Park – World Heritage
& Ramsar listed

Data sources
• Information derived from current or
planned projects
• Biophysical features – extensive; ready
access
• Social/cultural features – extensive;
discuss access
• Floodplain services – variable; derived
from biophysical data and managers
• Pressures – extensive analyses; risk
assessments underway
Scale
• Biogeographical or catchment scale
1:100 000 to 1:250 000
• Catchment scales 1:50 000 to 1:100 000
• Habitats / river reaches 1:10 000
Components
•
•
•
Inventory/mapping – GIS multiple scale
Floodplain services – indigenous,
biodiversity, tourism, recreation (fish
stocks, mitigation of climate change, cattle
grazing)
Risk assessment of major pressures –
invasive species, water pollution,
infrastructure, burning, climate change
Hierarchical approach to
wetland inventory
Level 1
Scale (nominal)

Location; altitude; area;
land systems; climate; hydrology;
vegetation
Wetland region
Level 3
Wetland complex
1:50 000
Location; physico-chemical and biological
features; classification; jurisdiction; ecosystem
services
Level 4

The Risk
Assessment
Framework
(modified from van Dam et al. 1999; Ramsar 2000)
Identification of the problem
(eg site assessment: sitespecific information on
stressor & environment)
Analysis
Identification of the effects
(field assessment: eg bioassays,
monitoring, surveys etc.)
Identification of the extent
of the problem
(eg chemical concs,spatial &
temporal distribution)
Identification of the risk
(comparison of effects with the
extent using a GIS framework)
Risk management/
Risk reduction
(manage inputs/
alter practices)
Monitoring
(use of early warning and
rapid assessment indicators/
GIS-based approach)
Major pressures
Major pressures – insidious effects of
climate change
Next steps
Further consultation – with participants,
advisors and stakeholders
Collation / analysis – based on previous and
current projects
Communication – discussing and finalising
analyses and outcomes
