 In February 2009, the Center for Biological Diversity, an environmental advocacy group, announced plans to sue the United States Fish and Wildlife Service and the Bureau of Land Management (BLM) for violations of the Endangered Species Act.The Center contends the Coyote Springs development and resultant loss of water resources and habitat would harm the desert tortoise and potentially hasten the extinction of the Moapa dace, both endangered species.The Fish and Wildlife Service and Nevada's water authority responded that they, too, are interested in protecting the Moapa dace, a small fish living in the Muddy River north of Las Vegas.
