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:

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%)	very rapid to severe deterioration	very high
Natural system modifications	likely in long term (beyond 4 years)	some of area/population (10-49%)	very rapid to severe deterioration	medium

Response (conservation actions taken for the trigger species and/or their habitats)
Protected areas	Management plan	Other action	Result
Some of site covered (10-49%)	Unknown	Some limited conservation initiatives are in place	low

Year	Protected Area	Designation	% overlap with IBA
1976	Haleakala	National Park	26
1976	Haleakala	Wilderness	16
1983	Waikamoi Macrosite	Easement	4
1983	Waikamoi Preserve	Biological Reserve	5
1986	Hanawi	Natural Area Reserve	7
2014	East Maui	Conservation Area	3
