Threats to the site (pressure)
Threat level 1	Threat level 2	Timing	Scope	Severity	Result
Agricultural expansion and intensification	marine and freshwater aquaculture - subsistence/artisinal aquaculture	happening now	majority/most of area/population (50-90%)	slow but significant deterioration	high
Biological resource use	hunting & collecting terrestrial animals - intentional use (species being assessed is the target)	happening now	whole area/population (>90%)	slow but significant deterioration	high
Human intrusions and disturbance	recreational activities	happening now	majority/most of area/population (50-90%)	slow but significant deterioration	high
Invasive and other problematic species and genes	invasive non-native/alien species/diseases - unspecified species	happening now	whole area/population (>90%)	slow but significant deterioration	high
Natural system modifications	dams & water management/use - dams (size unknown)	happening now	whole area/population (>90%)	very rapid to severe deterioration	very high
Pollution	domestic & urban waste water - type unknown/unrecorded	happening now	majority/most of area/population (50-90%)	slow but significant deterioration	high

Condition of the site (state), by habitat
Habitat	Habitat detail	Reference area (ha)	Actual area (ha)	Habitat quantity (% remaining)	Habitat quality (carrying capacity)	Result
Wetlands (inland)		30	30	-	good (> 90%)	favourable

Conservation actions taken at the site (response)
Protected-area designation	Management planning	Other conservation action	Result
Most of site (50-90%) covered (including the most critical parts for important bird species)	No management planning has taken place	Substantive conservation measures are being implemented but these are not comprehensive and are limited by resources and capacity	low
