The Pacific Islands are home to 44% of the threatened and endangered species listed under the Endangered Species Act. Our office works with state, territorial, and commonwealth governments, federal agencies, non-profit organizations, private landowners, universities, local communities, and citizen scientist partners in an effort to recover these unique species to a point where they no longer need the protections of the ESA. Below you will find a list of threatened and endangered species unique to the Pacific Islands.
With more than 20 listed endangered and threatened arthropods in Hawaii and the Pacific Islands, we, along with its partners, work to conserve endangered and threatened arthropods and their habitats and ecosystems to help prevent further species extinction. Hawaii’s picture-wing flies are a great example of evolution.
Mariana eight-spot butterfly (Hypolimnas octocula marianensis)
Blackline Hawaiian Damselfly (Megalagrion nigrohamatum nigrolineatum)
With more than 40 listed endangered and threatened bird species throughout the Pacific Islands, we, along with partners, work to conserve endangered and threatened birds and their habitats and ecosystems in order to prevent further species extinction. At least 32 birds species have gone extinct in Hawaii since 1778.
Ducks and Geese
- Band-Rumped Storm-Petrel (Oceanodroma castro)
Newell's townsend's shearwater (Puffinus auricularis newelli)
- Short-tailed albatross (Phoebastria albatrus)
By working with partners we protect endangered and threatened mammals and their habitats to prevent further species extinction. Hawaii’s state mammal is the ʻōpeʻapeʻa, Hawaiian Hoary Bat. There are also bats native to American Samoa, Guam and CNMI and other islands in the Pacific.
Pacific sheath-tailed Bat (Emballonura semicaudata semicaudata)
With nearly 400 listed endangered and threatened plant species throughout Hawaii and the Pacific Islands, we, with partners, work to conserve endangered and threatened plants and their habitats and ecosystems. In Hawaii, more than 90% of our flora is found nowhere else in the world.
Endangered Ferns and Fern Allies
Asplenium fragile var. insulare
Endangered Flowering Plants
Plantago princeps var. longibracteata
Plantago princeps var. princeps
We work with partners to conserve endangered and threatened reptiles and their habitats to prevent further species extinction. Although Hawaii has no native land reptiles, other islands in the Pacific have native reptiles, including skinks and even a salt water crocodile.
With more than 40 listed endangered and threatened snail species in Hawaii and the Pacific Islands, we, with partners, work to conserve endangered and threatened snails and their habitats and ecosystems. Hawaiian tree snails don’t eat plants, they scrape algae off the surface of leaves keeping them clean.
