On February 8, the U.S. Fish and Wildlife Service (FWS) proposed regulatory changes (Proposed Rule) focused on the application and approval process for Endangered Species Act (ESA) permits issued under Section 10. Section 10 of the ESA authorizes FWS to permit take of listed species where such take is necessary for scientific purposes or the enhancement of propagation or survival of the species, or where the take is incidental to an otherwise lawful activity. Section 10 permits are used for Candidate Conservation Agreements with Assurances and Safe Harbor Agreements, which are voluntary landowner agreements designed to benefit candidates or listed species, respectively. Section 10 permits also have been used to allow the take of listed species incidental to private development activities through a Habitat Conservation Plan (HCP), which involves the project proponent committing to certain conservation activities.
