Revisions to the Regulations for Petitions under the Endangered Species Act

We, the U.S. Fish and Wildlife Service and the National Marine Fisheries Service (Services), finalize changes to the regulations concerning petitions, to improve the content and specificity of petitions and to enhance the efficiency and effectiveness of the petition process to support species conservation. Our revisions to the regulations clarify and enhance the procedures by which the Services evaluate petitions under section 4(b)(3) of the Endangered Species Act of 1973, as amended. These revisions will also maximize the efficiency with which the Services process petitions, making the best use of available resources.
