The Center for Biological Diversity and Maricopa Audubon Society have sued the Bureau of Land Management and U.S. Fish & Wildlife Service for allowing cattle ranching in the Gila Box Riparian National Conservation Area (“Gila Box RNCA”) in southeastern Arizona. Plaintiffs argue that cattle grazing and accumulations of manure are harmful to the Gila Box RNCA and allege that the federal agencies are violating their obligations under the Endangered Species Act to protect a designated critical habitat and at least six listed species who live there. Plaintiffs seek declaratory and injunctive relief.
