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 ('triggering') IBA criteria.

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

Species	Red List	Season (year/s of estimate)	Size	IBA criteria
Black-faced Spoonbill Platalea minor	EN	winter (2003)	present	A1, A4i
Grey-tailed Tattler Tringa brevipes	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 (2010) is shown below.

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Natural system modifications	happe­ning now	some of popul­ation/area (10–49%)	slow decline (1–10% over 3 gener­ations)	medium

Response (conservation actions taken for the trigger species and/or their habitats)
Designation	Planning	Action	Result
Whole area (>90%) covered by appropriate conservation designation	A management plan exists, but it is out of date or not compre­hensive	Unknown	low

Year	Protected Area	Designation (management category)	% coverage of IBA
1977	Manko	国指定鳥獣保護区 (IV)	100
