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
Ryukyu Green-pigeon Treron permagnus	LC	resident	2003	present	A2
Whimbrel Numenius phaeopus	LC	passage	2003	present	A4i
A4iv Species group - soaring birds/cranes	n/a	passage	2003	min 20,000 individuals	A4iv

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 (2010) is shown below.

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Human intrusions and disturbance	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
Some of site covered (10-49%)	A management plan exists but it is out of date or not comprehensive	Unknown	low

Year	Protected Area	Designation	% overlap with IBA
