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
Hawaii Elepaio Chasiempis sandwichensis	NT	resident	1983	2,500 individuals	A1, A2
Palila Loxioides bailleui	CR	resident	2007	3,862 individuals	A1, A2
Hawaii Amakihi Chlorodrepanis virens	LC	resident	1983	87,624 individuals	A2
Iiwi Drepanis coccinea	VU	non-breeding	1983	482 individuals	A1, A2
Apapane Himatione sanguinea	LC	resident	1983	219 individuals	A2

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 (2009) is shown below.

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Invasive and other problematic species and genes	happening now	majority/most of area/population (50-90%)	slow but significant deterioration	high
Agricultural expansion and intensification	happening now	whole area/population (>90%)	slow but significant deterioration	high
Natural system modifications	happening now	some of area/population (10-49%)	very rapid to severe deterioration	high

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

Land comprising the Mauna Kea mamane-naio forest IBA is owned almost entirely by the State of Hawaii. Some of the land is leased to the U.S. Army as part of the Pohakuloa Training Area. Onwership information was unavailable or unlisted for 8% of the area. Less than 1% of the land is privately owned, and these lands are narrow slivers on the edges of the IBA.
