Populations of IBA trigger species

Species	Current IUCN Red List Category	Season	Year(s) of estimate	Population estimate	IBA Criteria Triggered
Long-tailed Duck Clangula hyemalis	VU	winter	2008-2013	1,000-4,000 individuals	A1
Goosander Mergus merganser	LC	non-breeding	2010-2013	21,000 individuals	A4i, B1i
Red-breasted Merganser Mergus serrator	LC	non-breeding	2010-2014	1,000-2,000 individuals	B1i
A4iii Species group - waterbirds	n/a	non-breeding	2010-2014	22,000-23,000 individuals	A4iii

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	livestock farming and ranching (includes forest grazing) - small-holder grazing, ranching or farming	happening now	small area/few individuals (<10%)	no or imperceptible deterioration	low
Biological resource use	gathering terrestrial plants - unintentional effects (species being assessed is not the target)	happening now	some of area/population (10-49%)	moderate to rapid deterioration	high
Energy production and mining	mining and quarrying	likely in long term (beyond 4 years)	some of area/population (10-49%)	slow but significant deterioration	medium
Human intrusions and disturbance	recreational activities	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
Invasive and other problematic species and genes	invasive non-native/alien species/diseases - named species	happening now	majority/most of area/population (50-90%)	slow but significant deterioration	high
Invasive and other problematic species and genes	problematic species/diseases of unknown origin - named species	happening now	majority/most of area/population (50-90%)	slow but significant deterioration	high
