USGS Scientist Matt Brooks is developing an annotated review of the literature pertaining to impacts associated with pack stock grazing in mountain meadows. This review serves two purposes: 1) to directly inform the development of the SEKI Wilderness Stewardship and Stock Use plan; and 2) to provide the basis for a joint USGS-NPS research proposal on pack stock grazing impacts being developed for the upcoming Servicewide Comprehensive Call (SCC).
This annotated report is planned for publication in a scientific journal in 2010. This report initiates a high-priority analysis of existing data associated with over 10,000 meadows in the central and southern Sierra Nevada Mountains. In addition, it serves as the basis for development of a BRD NRP-Research proposal for a new research project identified as a significant need in the literature that was reviewed for this project (effects of packstock on soils, vegetation, and small mammals in Sierra Nevada Meadows).
