Endangered and Threatened Wildlife and Plants; Revised Critical Habitat for the Northern Spotted Owl

The U.S. Fish and Wildlife Service (Service) proposes to revise the designated critical habitat for the northern spotted owl (Strix occidentalis caurina) under the Endangered Species Act of 1973, as amended (Act). Consistent with the best scientific data available, the standards of the Act, our regulations, and agency practice, we have initially identified, for public comment, approximately 13,962,449 acres (ac) (5,649,660 hectares (ha)) in 11 units and 63 subunits in California, Oregon, and Washington that meet the definition of critical habitat. In addition, however, the Act provides the Secretary with the discretion to exclude certain areas from the final designation after taking into consideration economic impacts, impacts on national security, and any other relevant impacts of specifying any particular area as critical habitat. We have identified and are considering a number of specific alternatives in this proposed rulemaking based on potential exclusions from the final rule. First, of the total area identified, we propose to exclude from the final designation approximately 2,631,736 ac (1,065,026 ha) of National Park lands, Federal Wilderness Areas, and other Congressionally reserved natural areas, as well as 164,776 ac (66,682 ha) of State Park lands. Second, we propose to exclude from a final designation approximately 936,816 ac (379,116 ha) of State and private lands that have a Habitat Conservation Plan, Safe Harbor Agreement, conservation easement, or similar conservation protection. And third, we are considering exclusion of an additional 838,344 ac (339,266 ha) of other non-Federal lands from the final designation. These specific alternatives will be considered on an individual basis or in any combination thereof. In addition, the final designation may not be limited to these alternatives, but may also consider other exclusions as a result of continuing analysis of relevant considerations (both scientific and economic, as required by the Act) and the public comment process. In particular, we solicit comments from the public on the physical and biological features currently identified in this proposal as being essential for the conservation of the species, whether all of the areas identified meet the definition of critical habitat, whether other areas would meet that definition, whether to make the specific exclusions we have proposed, and whether there are other areas that are appropriate for exclusion.
