Project Description:
The Bureau of Land Management (BLM) is proposing to gather approximately 498 wild horses from the Wassuk Herd Management Area (HMA), based on a gather efficiency of 80% in order to remove excess wild horses and apply population control measures. A total of approximately 400 excess wild horses would be removed from the HMA. Approximately 98 wild horses would be released back onto the range following the gather. Of these, about 39 mares would be vaccinated with PZP-22 (Porcine Zona Pellucida) fertility control vaccine which would assist with slowing population growth, maintaining population size within the Appropriate Management Levels (AMLs), and extend the time before another gather to remove excess wild horses would be needed. At the anticipated gather efficiency of 80%, 59 male and 39 female horses would be released back into the HMA utilizing a sex ratio of 60% males and 40% females. This would leave a post gather population of approximately 321 wild horses in the Wassuk HMA (which is above the AML range of 110-165) at the conclusion of the gather operations. A follow-up gather would need to occur to achieve the AML range and additional population controls would need to be implemented in these follow-up gathers. The proposed wild horse gather for the Wassuk HMA to remove excess animals and apply population control measures is scheduled to begin in September of 2012. It is anticipated that the horses in the Wassuk HMA would be re-gathered every two to three years over the next 10 years to re-vaccinate the mares and remove excess animals. Based on existing holding space and budgetary limitations, the BLM may not be able to meet necessary removal targets in order to achieve the low range of AML with the initial gather and follow-up gathers would be required to achieve AML and implement population control efforts.
Project Location:
The Wassuk HMA is located within the administrative jurisdiction of the BLM Carson City District (CCDO) within Lyon and Mineral Counties, Nevada (NV). The HMA is approximately 12 miles east-southeast of Yerington, NV and west of Walker Lake. HMA location maps are available in Appendix A. Upon completion of the gather, the HMA would be within the established AML range.
