What the agency says

We, the U.S. Fish and Wildlife Service (Service), propose to designate critical habitat for 9 animal species and 13 plant species from the Mariana Islands (the U.S. Territory of Guam and the Commonwealth of Northern Mariana Islands) under the Endangered Species Act (Act). In total across both the Territory and Commonwealth, approximately 59,886 acres (24,235 hectares) on the islands of Aguiguan, Alamagan, Asunci[oacute]n, Guam (including the island of Cocos), Pagan, Rota, Saipan, Sarigan, and Tinian fall within the boundaries of the proposed critical habitat designation. We also announce the availability of an economic analysis of the proposed designation of critical habitat for these species.
