In addition to the proposed action of a CTR gather, removal of wild horses outside identified HMAs within the project area will also be conducted. The HMAs included in this complex are Lost Creek, Stewart Creek, Green Mountain, Crooks Mountain and Antelope Hills(See Area Map, Appendix 2). The EA is a site-specific analysis of potential impacts that could result with the implementation of a proposed action or alternatives to the proposed action. The EA assists the BLM in project planning and ensuring compliance with the National Environmental Policy Act (NEPA), and in making a determination as to whether any “significant” impacts could result from the analyzed actions. “Significance” is defined by NEPA and is found in regulation 40 CFR 1508.27. An EA provides evidence for determining whether to prepare an Environmental Impact Statement (EIS) or a statement of “Finding of No Significant Impact” (FONSI). If the decision maker determines that this project has “significant” impacts following the analysis in the EA, then an EIS would be prepared for the project. If the decision maker determines that this project does not have “significant” impacts following the analysis, then an EA would be prepared for the project. A Decision Record may be signed for the EA approving one of the alternatives presented in the EA. 1.2 Background The Bureau of Land Management (BLM) Rawlins and Lander Field Offices propose to gather wild horses via helicopter and implement a retreatment of fertility control on captured mares that will be turned back to the range. The gather is expected to begin in early October of 2011 and will last approximately 25 days. The purpose of this environmental assessment (EA) is to analyze the impacts associated with the BLM’s proposal to Catch, Treat and Release wild horses from the Red Desert HMA Complex (Lost Creek, Stewart Creek, Green Mountain, Crooks Mountain and Antelope Hills) and to remove excess wild horses residing outside the HMA’s. The implementation of the gather is necessary to retreat mares that were treated in the fall of 2009 so that the remaining population levels are consistent with the appropriate management level (AML) for the herd management areas (HMAs) as well as to achieve a thriving natural ecological balance and a multiple use relationship with other resources within the project area. Implementing fertility control measures as part of the proposed action would slow the growth rate of the population that is returned to the HMA’s. In the event that weather or other factors prevent a gather at this time, the operation would be conducted as scheduling permitted in 2011. The BLM also anticipates the implementation of the proposed action will meet RMP objectives and remain in compliance with the State of Wyoming Consent Decree Agreement. 5 1.3 Need for the Proposal The Wild Free-Roaming Horses and Burros Act of 1971 (WFRHBA) established the framework for managing wild horse and burro populations on public lands. The WFRHBA provides in part, that the Department of Interior “manage wild free-roaming horses and burros in a manner that is designed to achieve and maintain a thriving natural ecological balance on the public lands.” P.L. 92-195 Section 1333 (as amended). BLM’s management of wild, free roaming horses must comply with law and policy pertaining to wild, free roaming
