The site was identified as important in 2010 because it was regularly supporting significant populations of the species listed below, meeting ('triggering') IBA criteria.

Populations meeting IBA criteria ('trigger species') at the site:

Species	Red List1	Season	Year(s)	Size	IBA criteria
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
A4iii Species group - waterbirds	n/a	passage	2001-2009	35,000 individuals	C4

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2010) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2010. The most recent assessment (2010) is shown below.

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Agricultural expansion and intensification	happening now	whole area/population (>90%)	very rapid to severe deterioration	very high
Natural system modifications	happening now	whole area/population (>90%)	very rapid to severe deterioration	very high
Invasive and other problematic species and genes	happening now	whole area/population (>90%)	very rapid to severe deterioration	very high
Biological resource use	happening now	whole area/population (>90%)	moderate to rapid deterioration	very high
Climate change and severe weather	happening now	majority/most of area/population (50-90%)	slow but significant deterioration	high
Energy production and mining	likely in long term (beyond 4 years)	some of area/population (10-49%)	moderate to rapid deterioration	medium
Residential and commercial development	likely in long term (beyond 4 years)	some of area/population (10-49%)	slow but significant deterioration	medium

Response (conservation actions taken for the trigger species and/or their habitats)
Protected areas	Management plan	Other 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

Year	Protected Area	Designation	% overlap with IBA
2004	Dolina Małej Wełny pod Kiszkowem	Special Protection Area (Birds Directive)	78
2008	Stawy Kiszkowskie	Site of Community Importance (Habitats Directive)	31
