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
Western Capercaillie Tetrao urogallus	LC	breeding	2004-2009	10-12 individuals	C6
Corncrake Crex crex	LC	breeding	2004-2009	40-60 males	C1
Ural Owl Strix uralensis	LC	breeding	2004-2009	15-20 breeding pairs	C6

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.
