The U.S. Fish & Wildlife Service (FWS) settled a lawsuit brought in 2021 by the Center for Biological Diversity, represented by Blue Ocean Law, which challenged the agency’s failure to designate critical habitat for nine endangered species in Micronesia. Under the agreement, FWS must designate critical habitat for the Pacific sheath-tailed bat, Slevin’s skink, Mariana eight-spot butterfly, Mariana wandering butterfly, Rota blue damselfly, humped tree snail, Langford’s tree snail, Guam tree snail, and the fragile tree snail by June 26, 2025.
