RE-INTRODUCTION IN SHOSHONE, CALIFORNIA This Safe Harbor Agreement (Agreement), effective and binding on the date of Permit issuance, is between Susan Sorrells (Landowner) and the U.S. Department of the Interior, Fish and Wildlife Service (Service), hereinafter referred to as the “Parties.” Service: The Service designates the following as the Agreement Contact: Assistant Field Supervisor U.S. Fish and Wildlife Service 777 East Tahquitz Canyon Way, Suite 208 Palm Springs, California 92262 760-322-2070 Landowner: P.O.

The specific goals of this Agreement are to translocate wild (non-captive) Amargosa voles from a source population, informed by genetic analyses, to re- introduce and establish a self-sustaining population of Amargosa voles within its historical range on Landowner lands. Enrolled Lands and Core Area The properties subject to this Agreement (Enrolled Property) consist of two parcels owned by the Landowner: 1) APN 046-120-26 (220 acres) and 2) APN 046-120-25 (247 acres), totaling 467 acres. While this agreement covers the entire 467 acres, Beneficial Management Activities (including translocation and re-introduction) will only occur in approximately 0.5 acres of marsh habitat within the Enrolled Property where restoration activities have previously been implemented to return the habitat to its natural condition. This area (Core Area) consists of 3 connected marsh sites (Marshes 31, 31A, and 31B) on the west side of Highway 127 near the north end of Shoshone, California. A more detailed description and maps of the Enrolled Property are provided in section 3.1 of this Agreement. Regulatory Framework Sections 2, 7, and 10 of the Endangered Species Act (Act) of 1973, as amended, allow the U.S. Fish and Wildlife Service to enter into this SHA. Section 2 of the Act states that encouraging interested parties, through Federal financial assistance and a system of incentives, to develop and maintain conservation programs is a key to safeguarding the Nation’s heritage in fish, wildlife, and plants. Section 7 of the Act requires the Service to review programs that we administer and to utilize such programs in furtherance of the purposes of the Act. By entering into this SHA, we are utilizing our Recovery Program to further the conservation of the Nation’s fish and wildlife. Lastly, section 10(a)(1)(A) of the Act authorizes the issuance of permits to “enhance the survival” of a listed species. This Agreement follows the Service’s Safe Harbor Agreement policy (64 Federal Register [FR] 32717) and regulations (50 CFR 17.22(c) and 50 CFR 17.32(c)) and implements the intent of the Parties to follow the procedural and substantive requirements of section 10(a)(1)(A) of the Endangered Species Act of 1973, as amended (Act). 6 For the purposes of this Agreement, we define “translocation” according to the International Union for Conservation of Nature and Natural Resources (IUCN) position statement (IUCN 1987) as “the movement of living organisms from one area with free release in another.” SHA Standard and Background Before entering into a SHA, the Service must determine that the conservation measures to be implemented will contribute to recovering the species by providing a net conservation benefit. Safe Harbor Agreements encourage voluntary conservation efforts by non-Federal landowners and provide them assurances that future property-use restrictions will not be imposed if those efforts attract covered species to their Property or result in increased numbers or distributions of covered species already present. In return for voluntary conservation commitments, the Safe Harbor
