Populations of IBA trigger species

Species	Current IUCN Red List Category	Season	Year(s) of estimate	Population estimate	IBA Criteria Triggered
Bean Goose Anser fabalis	LC	passage	2008-2009	15,000-18,000 individuals	C3
Greater White-fronted Goose Anser albifrons	LC	passage	2008-2009	10,000-12,000 individuals	C3

Note: This table presents the IBA criteria triggered and the species that triggered then at the time of assessment, the current IUCN Red List category may vary from that which was in place at that time.

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	whole area/population (>90%)	very rapid to severe deterioration	very high
Biological resource use	hunting & collecting terrestrial animals - intentional use (species being assessed is the target)	happening now	whole area/population (>90%)	moderate to rapid deterioration	very high
Biological resource use	hunting & collecting terrestrial animals - persecution/control	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
Climate change and severe weather	drought	happening now	majority/most of area/population (50-90%)	slow but significant deterioration	high
Energy production and mining	renewable energy	likely in long term (beyond 4 years)	some of area/population (10-49%)	moderate to rapid deterioration	medium
Invasive and other problematic species and genes	invasive non-native/alien species/diseases - unspecified species	happening now	whole area/population (>90%)	very rapid to severe deterioration	very high
Invasive and other problematic species and genes	problematic native species/diseases - unspecified species	happening now	majority/most of area/population (50-90%)	moderate to rapid 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
Natural system modifications	fire & fire suppression - increase in fire frequency/intensity	happening now	small area/few individuals (<10%)	no or imperceptible deterioration	low
Residential and commercial development	tourism and recreation areas	likely in long term (beyond 4 years)	some of area/population (10-49%)	slow but significant deterioration	medium

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)	No management planning has taken place	Very little or no conservation action taking place	low
