Threats to the site (pressure)
Threat Level 1 Threat Level 2 Timing Scope Severity Result
Invasive and other problematic species and genes invasive non-native/alien species/diseases - named species happening now some of area/population (10-49%) slow but significant deterioration medium
Invasive and other problematic species and genes problematic native species/diseases - named species happening now small area/few individuals (<10%) slow but significant deterioration low
Natural system modifications dams & water management/use - small dams happening now some of area/population (10-49%) slow but significant deterioration medium
Residential and commercial development commercial and industrial development likely in long term (beyond 4 years) some of area/population (10-49%) moderate to rapid deterioration medium
Transportation and service corridors roads and railroads likely in long term (beyond 4 years) small area/few individuals (<10%) moderate to rapid deterioration low

Condition of habitat (state)
Habitat Habitat Detail Reference Area (ha) Actual Area (ha) % of habitat remaining % of carrying capacity (overall) Result
Wetlands (inland) Freshwater lakes & pools 0 0 moderate (70-90%) good (> 90%) near favourable

Conservation actions taken at site (response)
Conservation Designation Management Planning Conservation Action Result
Most of site (50-90%) covered (including the most critical parts for important bird species) A comprehensive and appropriate management plan exists that aims to maintain or improve the populations of qualifying bird species Substantive conservation measures are being implemented but these are not comprehensive and are limited by resources and capacity medium
