Listing Endangered and Threatened Wildlife and Designating Critical Habitat; 12-month Determination on How to Proceed with a Petition to Revise Designated Critical Habitat for Elkhorn and Staghorn Corals

Zusammenfassung

We, the National Marine Fisheries Service (NMFS), announce our 12-month determination on how to proceed with a petition to revise the critical habitat designation for elkhorn (Acropora palmata) and staghorn (A. cervicornis) corals pursuant to section 4(b)(3)(D)(ii) of the Endangered Species Act (ESA) of 1973, as amended. Elkhorn and staghorn corals are listed as threatened throughout their ranges and have designated critical habitat consisting of substrate of suitable quality and availability to support successful larval settlement and recruitment, and successful reattachment and recruitment of asexual fragments in water depths shallower than 30 meters in four areas in Florida, Puerto Rico, and the U.S. Virgin Islands. The petition seeks to extend the northern boundary of designated critical habitat in the Florida area to the Lake Worth Inlet, which is approximately 15.5 miles (25 km) north of the current boundary at Boynton Beach Inlet, based on the discovery of staghorn corals north of the existing critical habitat boundary. We have evaluated the available scientific information and have decided, based on the adequacy of the existing, recent designation to meet the corals' conser
