Over a challenge by environmental groups, Center for Biological Diversity et al., v, Kenneth Salazar et al., a D.C. district approves the FWS’s designation of critical habitat for the Cape Sable Seaside Sparrow, despite the agency’s decision to exclude habitat of the only subpopulation situated west of northwest Shark River Slough. The designation had come in response to an earlier case filed by environmental plaintiffs: Biodiversity Legal Found. v. Norton, 285 F. Supp. 2d 1, 14 (D.D.C. 2003).
