Kokia drynarioides is an endangered shrub endemic to dry forests on the island of Hawaii. Overgrazing by livestock, competition from invasive weeds and habitat disturbances due to development have reduced this species to less than 10 plants in only three naturally occurring populations. Kokia drynarioides is a food source for nectar-drinking birds called honeycreepers, which have become endangered as a result of this decline. Federal and state land management agencies are working to carefully with public gardens and conservation professionals to manage sensitive habitats to reduce threats endangered species like Kokia drynarioides.
