The U.S. Fish and Wildlife Service (FWS) provides agreements with non-Federal landowners called Candidate Conservation Agreements with Assurances (CCAAs) to address at-risk species that may become listed under the Endangered Species Act in the future. Property owners who commit to a CCAA receive regulatory assurances that the FWS will not require additional conservation measures beyond those in the CCAA without their consent. If the species is listed, documents supporting the CCAA allow a prescribed amount of incidental take that could result from actions implemented under the agreement. A Candidate Conservation Agreement (CCA) is a more basic agreement that the FWS can develop with any other partner. A CCA does not provide a permit for take and does not require providing a notice of the agreement in the Federal Register. The FWS provides additional information about these two agreements.
