IBA Justification

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
Whimbrel Numenius phaeopus	LC	passage	2003	present	A4i
Marsh Grassbird Helopsaltes pryeri	NT	breeding	2003	present	A1, A3
Ochre-rumped Bunting Emberiza yessoensis	NT	breeding	2003	present	A3
