We will make a final determination to designate critical habitat for three Hawaiian plant species (Mezoneuron kavaiense, Isodendrion pyrifolium, and Bidens micrantha ctenophylla) under the Endangered Species Act. These three species are listed as endangered. We are correcting maps for four other listed plant species with currently designated critical habitat. These species are found in seven multispecies critical habitat units on lands owned by the U.S. National Park Service, State of Hawaii, County of Hawaii, and private interests. Fifty-five percent of the area is already designated as critical habitat for previously listed plant and animal species.
