The site was identified as important in 2004 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
Latham's Snipe Gallinago hardwickii	NT	breeding	2003	present	A3
Steller's Sea-eagle Haliaeetus pelagicus	VU	winter	2003	present	A3
Middendorff's Grasshopper-warbler Helopsaltes ochotensis	LC	breeding	2003	present	A3
Siberian Blue Robin Larvivora cyane	LC	breeding	2003	present	A3

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2004) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2004. The most recent assessment (2015) is shown below.

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Invasive and other problematic species and genes	happening now	some of area/population (10-49%)	moderate to rapid deterioration	high
Human intrusions and disturbance	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
Pollution	happening now	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
Whole area of site (>90%) covered by appropriate conservation designation	Not assessed	Some limited conservation initiatives are in place	low
