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 the Endangered Leatherback Sea Turtle

摘要

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 leatherback sea turtles pursuant to the Endangered Species Act (ESA) of 1973, as amended. The petition from Sierra Club requested a revision of the existing critical habitat designation for the leatherback sea turtle by adding the coastline and offshore waters of the Northeast Ecological Corridor in Puerto Rico. Based on the lack of reasonably defined physical or biological features that are essential to the leatherback turtle's conservation and that may require special management considerations or protection, we are denying the petitioned revision.
