Year of most recent IBA criteria assessment: 2016

Populations of IBA trigger species

Species	Current IUCN Red List Category	Season	Year(s) of estimate	Population estimate	IBA Criteria Triggered
Arctic Tern Sterna paradisaea	LC	breeding	2009-2014	min 43 breeding pairs	C6
Western Marsh-harrier Circus aeruginosus	LC	breeding	2011-2015	36-40 breeding pairs	C6
Hen Harrier Circus cyaneus	LC	breeding	2011-2015	1-3 breeding pairs	C6

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) - agro-industry grazing, ranching or farmin	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
Climate change and severe weather	habitat shifting and alteration	happening now	majority/most of area/population (50-90%)	very rapid to severe deterioration	very high
Human intrusions and disturbance	recreational activities	happening now	small area/few individuals (<10%)	moderate to rapid deterioration	low
Human intrusions and disturbance	work and other activities	happening now	some of area/population (10-49%)	moderate to rapid deterioration	high
Invasive and other problematic species and genes	invasive non-native/alien species/diseases - named species	happening now	some of area/population (10-49%)	very rapid to severe deterioration	high
Invasive and other problematic species and genes	problematic native species/diseases - named species	likely in short term (within 4 years)	majority/most of area/population (50-90%)	moderate to rapid deterioration	high
Natural system modifications	other ecosystem modifications	likely in short term (within 4 years)	small area/few individuals (<10%)	moderate to rapid deterioration	low
Pollution	agricultural & forestry effluents - nutrient loads	happening now	small area/few individuals (<10%)	moderate to rapid deterioration	low
