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
Black-tailed Gull Larus crassirostris	LC	breeding	2003	present	A4i

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.

State (condition of the trigger species' habitats)
Habitat	Quantity (% remaining)	Quality (% carrying capacity)	Result
Grassland	good (> 90%)	moderate (70-90%)	near favourable

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Climate change and severe weather	likely in long term (beyond 4 years)	whole area/population (>90%)	moderate to rapid deterioration	high
Biological resource use	likely in long term (beyond 4 years)	majority/most of area/population (50-90%)	slow but significant deterioration	medium
Invasive and other problematic species and genes	likely in long term (beyond 4 years)	majority/most of area/population (50-90%)	slow but significant deterioration	medium
Transportation and service corridors	past (and unlikely to return) and no longer limiting	majority/most of area/population (50-90%)	moderate to rapid deterioration	low
Human intrusions and disturbance	likely in long term (beyond 4 years)	some of area/population (10-49%)	no or imperceptible deterioration	low

Response (conservation actions taken for the trigger species and/or their habitats)
Protected areas	Management plan	Other action	Result
Little/none of site covered (<10%)	No management planning has taken place	Very little or no conservation action taking place	negligible

Year	Protected Area	Designation	% overlap with IBA
1973	Soya tobu	沿岸水産資源開発区域	20
2013	Common fishery right area(Hokkaido)	共同漁業権区域	20
