Lands comprising the Hamakua Forest Important Bird Area are owned by the Federal Government, the State of Hawai`i, and several different private landowners. Hakalau Forest National Wildlife Refuge is owned by the U.S. Fish and Wildlife Service. Laupahoehoe Natural Area Reserve and the Hamakua, Hilo, Hilo Watershed, and Manowaiale`e Forest Reserves are owned by the State of Hawai`i. Private landowners include Kamehameha Schools, Queen Liliuokalani Trust, and Parker Ranch. Despite their misleading names, two private parcels owned by Hawaii Forest Preservation and the Ohana Sanctuary are in reality associated with the logging company Koa Timber Inc.
