Montane wet forest on the windward slopes of East Maui are the last habitat for the po‘ouli.
The East Maui Conservation Area includes large tracts of state-owned forest reserve.
Anuntold number of native invertebrates, such as this Hawaiian happyfacespider, are nested within East Maui's native ecosystems.
The rugged upper slopes of East Maui have never been converted from native forest.
Non-native pigs, escaped into the wild, pose a severe threat to native ecosystems.
East Maui Conservation Area Profile
Ecological Systems: Four ecological systems of East Maui were selected as conservationtargets, each bearing nested natural communities and species (discussedbelow).
Selected stream occurrences: Maui bears manyhigh quality streams, and the four streams selected: Hanawī, Honokōhau, Kahakuloa, and Ōhe'o Streams are among thelargest and highest quality streams on the island (Hawai‘i Stream Assessment 1991). Eachbears a rich complement of native macrofauna and high volume, high qualitywater in a channel with high structural heterogeneity.
Special Ecological Features:
The East Maui Forest Bird Concentration is one ofthe most significant in the archipelago, bearing ten avian species, including seventaxa endemic to the island, and five endangered species.
East Maui is part of the Maui Nui Waterbird Concentration, defined as three core wetlands and at least five of seven supporting wetland sites identified by the USFWSWaterbird Recovery Plan (2005). These include coastal and lowlandsites outside of the ecological system targets.Nested Targets (Selected examples):
‘Ōhi‘a/Uluhe Lowland Wet
‘Ōhi‘a/Mixed Shrub Montane
‘Ōhi‘a Mixed Lowland Mesic
Pleomele Lowland Mesic
Hawaiian Montane Bog
Mixed Fern/Shrub Wet Cliff Community
Mixed Shrub Dry Cliff Community
Montane Piping Cave Community
There are manyconstituent native species that comprise the natural communities of the ConservationArea. Highlights include over 30 rare/endangered plant species, over 50endemicflowering plant species, and an untold number of endemic invertebrate species likelynumbering in the thousands.Major Threats:Uncontrolledferal ungulates (primarily pigs, goats, deer); a variety ofinvasivealien plants, including Miconia, Clidemia, and Psidium, and wildfire at lower dry and mesic settings. .
