The site was identified as internationally important for bird conservation in 2004 because it was regularly supporting significant populations of the species listed below, meeting IBA criteria.

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

Species	Red List	Season (year/s of estimate)	Size	IBA criteria
Greater White-fronted Goose Anser albifrons	LC	passage (2003)	present	A4i

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 key species' habitats)
Habitat	Quantity (% remaining)	Quality (% carrying capacity)	Result
Artificial/Terrestrial	good (>90%)	very poor (<40%)	very unfavourable

Pressure (threats to the key species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Agricultural expansion and intensification	past (and unlikely to return) and no longer limiting	most of popul­ation/area (50–90%)	moderate deteri­oration (10–30% in 3 gener­ations)	low

Response (conservation actions taken for the key species and/or their habitats)
Designation	Planning	Action	Result
Little/none of site covered (<10%)	Not assessed	Substantive conservation measures are being implemented, but these are not comprehensive and are limited by resources and capacity	low

Year	Protected Area	Designation (management category)	% coverage of IBA
-	Mukawa Wildlife Protection Area (Local)	Other (-)	-
1998	Mukawa kako	都道府県指定鳥獣保護区 (IV)	3

Habitat	% of IBA	Habitat detail
Artificial/Terrestrial	major (>10)	Rice paddies; Arable land
Marine Intertidal	minor (<10)
Marine Neritic	minor (<10)
