Proposed Rules for Changes to Critical Habitat for Federally Listed Species

On May 12, 2014, the U.S. Fish and Wildlife Service and National Marine Fisheries Service published proposed rules to implement certain changes to critical habitat procedures and designation/revision of critical habitat and to establish a policy for determining areas excluded from critical habitat designation. The changes are proposed as the result of litigation and court decisions that have either substantiated the Services authorities or clarified areas of confusion in the Endangered Species Act and/or the implementing regulations. The proposed changes would pertain only to new critical habitat designations. Existing critical habitat designated for species would not be reevaluated based on the new criteria. However, revisions made to existing designated critical habitat after the rules become final would be guided by the new regulations. Comments were received until July 11, 2014.
