Federal agencies are seeking to reinterpret a key word in the Endangered Species Act that could weaken habitat protections for certain at-risk species, according to two wildlife biologists at North Carolina State University. The U.S. Fish and Wildlife Service and the National Marine Fisheries Service have proposed a rule that would exclude habitat modification and degradation from the regulatory definition of “harm” under the Endangered Species Act. “If we lose critical habitat protections for threatened and endangered species … they could face a heightened risk of extinction,” said Chris Moorman, a biology professor. Roland Kays, a research professor of fisheries, wildlife and conservation biology, added: “The Endangered Species Act, as it is written, is crucial to the protection and recovery of at-risk species across the country. And while there have been many attempts to change the law over the years, it’s held up and worked as intended.”
