Endangered and Threatened Wildlife and Plants; Designation of Critical Habitat for Three Plant Species on Hawaii Island

We, the U.S. Fish and Wildlife Service (Service), designate critical habitat for Bidens micrantha ssp. ctenophylla (kookoolau), Isodendrion pyrifolium (wahine noho kula), and Mezoneuron kavaiense (uhiuhi) respectively, under the Endangered Species Act (Act). In total, approximately 11,640 acres (ac) (4,711 hectares (ha)) in North Kona and South Kohala on Hawaii Island fall within the boundaries of the critical habitat designation. Approximately 72 percent of this area is already designated as critical habitat for 42 plants and the Blackburn's sphinx moth (Manduca blackburni). We are excluding, under section 4(b)(2) of the Act, approximately 7,027 ac (2,844 ha) of land on the island of Hawaii that meet the definition of critical habitat from this final critical habitat designation.
