Vale District Office 100 Oregon Street Vale, Oregon 97918-9630 http://www.or.blm.gov/Vale/ IN REPLY REFER TO: 1601, LCGMA November 6, 2003 Dear Interested Public: I am pleased to present the Louse Canyon Geographic Management Area (LCGMA) Evaluation for your review and consideration. This document summarizes the results of the LCGMA rangeland health assessment and evaluation, and presents recommendations to address the assessment findings. This document ends the assessment and evaluation phase, and outlines a range of alternatives for upcoming NEPA analysis. The decisions that can be expected to flow from the NEPA analysis are activity level decisions, rather than land use level decisions, which may be implemented in accordance with and subject to the guiding land use plan – the Southeastern Oregon Resource Management Plan and Final EIS. We would appreciate your comments. We are particularly interested in your views on the range of alternatives and preferred alternative recommended. The team has worked diligently to involve the public and include a range of alternatives for analysis that reflect the input received thus far. Of course there have been some recommendations that are outside the scope of the LCGMA Evaluation which are not addressed here in. We are anxious to begin the NEPA analysis, but first we want to give the interested public the opportunity to comment on the range of alternatives proposed. If you would like to comment, please do so in writing. Address your comments to the Jordan Field Manager, Vale District BLM at the address on the letterhead above. To be considered, your comments must be received in this office by January 1, 2004. Sincerely, Jerry L.

Resource conditions are described for nearly 523,000 acres of public land. The evaluation pertains to Louse Canyon, Campbell, Anderson, Star Valley Community, Quinn, and Little Owyhee BLM grazing allotments and is based on an interdisciplinary team (ID) field assessment conducted during the summer of 2000. Field data gathered support the following general observations about LCGMA: • With some localized exceptions, native uplands support healthy, diverse plant communities that have been grazed at conservative stocking levels and at times of the year that allow for rangeland processes to function properly. Water sources for livestock grazing administration are limited in both distribution and abundance for much of the unit. • Soil compaction resulting from historic grazing use near former homestead areas is probably still influencing the productivity of lower elevation rangelands. Evidence of accelerated soil erosion is generally absent in upland areas. • Riparian and wetland habitats that have been grazed during summer and fall (hot season) for the last several decades are in need of grazing season adjustments in order to attain range health standards. Most riparian and wetland areas with perennial water sources are Functioning at Risk, and accelerated erosion is ongoing in certain stream reaches. Key vegetation components necessary to support proper functioning riparian systems are still present in most areas • Seedings and brush control projects have influenced about 43,000 acres (approximately 8%) of LCGMA. Starvation Seeding is the only monotypic (pure grassland habitat with little or no shrub cover) rangeland type present. Substantial sagebrush recolonization has taken place in most treatment areas. • More than 96% of all sagebrush steppe communities are complex shrubland habitat types capable of supporting greater sage-grouse and other animals that use sagebrush habitats. Habitat connectivity is excellent and fragmentation from fires and other historic treatments is proportionally low. • Bald eagles (winter residents) are the only federally listed vertebrate occupying LCGMA. There are no federal or state listed plants or invertebrates present. • LCGMA currently supports few noxious and invasive upland plant species. Whitetop invasions are present on the main stem of the Owyhee River and along primary access roads at the present time. iii Chapter 1 – Background Chapter 1 – Background A. History and Process for Assessing Rangeland Health Standards Subsequent to the approval of revised BLM grazing regulations in 1995, BLM State Directors were assigned the task of developing state level rangeland health standards (Title 43 Code of Federal Regulations [CFR] 4180.2). The process of developing standards and defining standard indicators was conducted in consultation with BLM Resource Advisory Councils (RAC’s). The purpose for setting standards and identifying their indicators was to provide BLM with a rational basis for determining whether current management is meeting the Fundamentals of Rangeland Health as described under 43 CFR 4180.1. See Appendix A, Fundamentals of Rangeland Health, for a description of objectives and principles underlying rangeland health standards. On August 12, 1997, Interior Secretary Bruce Babbitt approved the Oregon/Washington BLM Standards and Guides (S&G’s) for Rangeland Health. BLM field offices in Oregon/Washington were subsequently directed to conduct assessments and then use that assessment information to craft range health evaluations in relation to the state standards. These sequential actions were therefore used to implement 43 CFR 4180.1 and .2. In order to accomplish this assessment and evaluation
