the court ruled in favor of conservationists and upheld the precedence of federal laws before state control of wildlife. having violated the endangered species act, hawaii state was required to remove all feral animals from the mountainside. this decision was followed by a second court order in 1981. a public hunting program removed many of the feral animals, at least temporarily. an active control program is in place, though it is not conducted with sufficient rigor to allow significant recovery of the māmane-naio ecosystem. there are many other species and ecosystems on the island, and on mauna kea, that remain threatened by human development and invasive species.
