habitats. Procedures for receiving and considering petitions to revise 
the lists and for conducting periodic reviews of listed species also are 
established.

portions of the Endangered Species Act of 1973, as amended (16 U.S.C. 
1531 et seq.), that pertain to the listing of species and the 
determination of critical habitats.
