The site was identified as internationally important for bird conservation 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 List	Season (year/s of estimate)	Size	IBA criteria
Hawaiian Goose Branta sandvicensis	NT	resident (2002)	251 birds	A1, A2, A4i
Hawaiian Petrel Pterodroma sandwichensis	EN	breeding (1994)	450 pairs	A1, A4ii
Poo-uli Melamprosops phaeosoma	EX	resident (1996)	rare	A1, A2
Maui Alauahio Paroreomyza montana	EN	resident (1980)	min 34,839 birds	A1, A2
Maui Nukupuu Hemignathus affinis	EX	resident (1996)	1 birds	A1, A2
Maui Parrotbill Pseudonestor xanthophrys	CR	resident (1980)	502 birds	A1, A2
Hawaii Amakihi Chlorodrepanis virens	LC	resident (1980)	min 43,930 birds	A2
Iiwi Drepanis coccinea	VU	resident (1980)	min 18,812 birds	A1, A2
Apapane Himatione sanguinea	LC	resident (1980)	min 93,818 birds	A2
Akohekohe Palmeria dolei	CR	resident (1980)	min 3,753 birds	A1, A2

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	most of popul­ation/area (50–90%)	rapid decline (>30% over 3 gener­ations)	very high
Natural system modifications	likely in long term (>4 years)	some of popul­ation/area (10–49%)	rapid decline (>30% over 3 gener­ations)	medium

Response (conservation actions taken for the trigger species and/or their habitats)
Designation	Planning	Action	Result
Some of area covered (10–49%)	Unknown	Some limited conservation initiatives are in place	low

Year	Protected Area	Designation (management category)	% coverage of IBA
1976	Haleakala	National Park (II)	26
1976	Haleakala	Wilderness (Ib)	16
1983	Waikamoi Macrosite	Easement (V)	4
1983	Waikamoi Preserve	Biological Reserve (IV)	5
1986	Hanawi	Natural Area Reserve (V)	7
2014	East Maui	Conservation Area (V)	3

Most of the lands comprising the Haleakala IBA are owned by the State of Hawai`i (63%) and the National Park Service (25%). Haleakala IBA also includes Waikamoi Preserve (5%), which is managed by The Nature Conservancy and owned by Alexander & Baldwin, and some additional land owned by Alexander & Baldwin (7%). State lands include Hanawi Natural Area Reserve (7%), Department of Hawaiian Home Lands (6%), Ko`olau, Hana, Kipahulu, Kahikinui, Kula, and Makawao State Forest Reserves (50%), and Polipoli Spring State Recreation Area (<1%).
