The site was identified as important in 2009 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
Black-necked Crane Grus nigricollis	NT	winter	1991	160 individuals	A1, A4i
A4iii Species group - waterbirds	n/a	unknown	2003	min 20,000 individuals	A4iii

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2009) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2009. The most recent assessment (2008) is shown below.

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Pollution	likely in long term (beyond 4 years)	some of area/population (10-49%)	slow but significant deterioration	medium
Human intrusions and disturbance	happening now	small area/few individuals (<10%)	slow but significant deterioration	low
Biological resource use	happening now	small area/few individuals (<10%)	slow but significant deterioration	low
Energy production and mining	happening now	small area/few individuals (<10%)	slow but significant deterioration	low
Agricultural expansion and intensification	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
Most of site (50-90%) covered (including the most critical parts for important bird species)	A management plan exists but it is out of date or not comprehensive	Substantive conservation measures are being implemented but these are not comprehensive and are limited by resources and capacity	medium

Year	Protected Area	Designation	% overlap with IBA
1985	Napahai	Nature Reserve	100
2004	Napahai Wetland	Ramsar Site, Wetland of International Importance	87
