USFWS proposes to list the Black Creek crayfish (Procambarus pictus), a crayfish species from Florida, as an endangered species under ESA. They also propose to designate critical habitat for the Black Creek crayfish under the Act. In total, approximately 1,056 kilometers (656 miles) of streams in Clay, Duval, Putnam, and St. Johns Counties, Florida, fall within the boundaries of the proposed critical habitat designation. If finalized this rule would extend the Act's protections to this species and its designated critical habitat. They also announce the availability of an economic analysis of the proposed critical habitat designation for the Black Creek crayfish. They will accept comments received or postmarked on or before 12 November 2024.
