The site was identified as important in 1999 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
Milky Stork Mycteria cinerea	EN	breeding	1984	10-30 individuals	A1
Royal Spoonbill Platalea regia	LC	breeding	1970-1979	present	A4i
Black-headed Ibis Threskiornis melanocephalus	LC	breeding	1970-1979	present	A4i

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (1999) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 1999. The most recent assessment (2017) is shown below.

State (condition of the trigger species' habitats)
Habitat	Quantity (% remaining)	Quality (% carrying capacity)	Result
Forest	moderate (70-90%)	moderate (70-90%)	unfavourable

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Human intrusions and disturbance	happening now	small area/few individuals (<10%)	slow but significant deterioration	low

Response (conservation actions taken for the trigger species and/or their habitats)
Protected areas	Management plan	Other action	Result
Not assessed	Not assessed	Not assessed	not assessed

Year	Protected Area	Designation	% overlap with IBA
-	Pulau Dana	Cagar Alam	8
1984	Pulau Kasa	Suaka Margasatwa	100

Habitat1	Habitat detail	% of IBA
Forest	Mangrove forest (tropical), Heath forest (tropical)	major (>10)
Marine Coastal/Supratidal		major (>10)
