Endangered and Threatened Wildlife and Plants; Proposed Designation of Critical Habitat for Navarretia fossalis (spreading navarretia)

Résumé

We, the U.S. Fish and Wildlife Service (Service), propose to designate critical habitat for Navarretia fossalis (spreading navarretia) pursuant to the Endangered Species Act of 1973, as amended (Act).

We have excluded 26,785 ac (10,839 ha) of essential habitat in Riverside and San Diego Counties from this proposed critical habitat designation.

In developing this proposal, we evaluated those lands determined to be essential to the conservation of Navarretia fossalis to ascertain if any specific areas warrant non-inclusion or exclusion from critical habitat pursuant to sections 4(a)(3) and 4(b)(2) of the Act. On the basis of our evaluation, we have determined
