Hawaii is home to a wide variety of ecological habitats with more than 1000 native plant species; many are threatened or endangered.

90% of the terrestrial species are endemic (unique to the region), and many are threatened or endangered. Habitat loss and alteration, and the spread of invasive plants have all contribute to extinctions and ecosystem decline. Sea level rise is expected to severely impact low-lying areas, including coastal plants, nesting seabirds, seals, and turtles.
