Continued . . .

Hanalei NWR includes 917 acres of steep wooded slopes and relatively flat bottomlands along the Hanalei River. The hillsides are dominated by introduced trees and shrubs, while most of the lowlands were historically used for taro and rice production. Prior to modifications for agriculture, the river valley may have consisted of a braided river system with a mosaic of riverine, riparian, and seasonal freshwater marshlands supporting abundant native wildlife.

Fossils of ancient wetlands indicate that the native wildlife that remain are a remnant of the abundance and diversity of species that once inhabited these islands.

Today, approximately 49 species of birds, including endangered ae‘o (Hawaiian stilt), ‘alae ke‘oke‘o (Hawaiian coot), ‘alae ‘ula (Hawaiian moorhen), nene (Hawaiian goose), and koloa maoli (Hawaiian duck), migratory waterfowl and shorebirds such as the common koloa mapu (northern pintail) and ‘ulili (wandering tattler), rare visitors such as the killdeer, and at least 18 introduced resident species can be found on the refuge. The refuge also provides habitat for the endangered ‘ope‘ape‘a (Hawaiian hoary bat), Hawaii’s only native terrestrial mammal.

Threats to endangered waterbirds include loss and degradation of habitat, historic over-hunting, disease, predation by introduced predators, and other invasive species including the feral mallard that can compete for limited wetlands resources and crossbreed with the endangered koloa maoli.
