The purpose of this EA is to evaluate the potential effects of authorizing livestock grazing on three allotments within the 26,469-acre Snake/Pine Rangeland Analysis Area (SPRAA), which includes 415 acres of private land and 2 acres of Bureau of Land Management (BLM) land. The allotments being evaluated are North Pine, Double Pine and Snake River. These allotments are administered by the Whitman Ranger District and are located within the Hells Canyon National Recreation Area (HCNRA) of the Wallowa-Whitman National Forest. This document is organized into five parts: Chapter 1. Purpose and Need for Action: This section includes information on the history of the project proposal, the purpose of and need for the project, the proposal for achieving that purpose and need, and key issues used to formulate alternatives, develop mitigation, and track effects and other issues that did not drive alternatives but were addressed in this analysis. Chapter 2. Alternatives, including the Proposed Action: This section provides a more detailed description of the proposed action, as well as alternative methods for achieving the stated purpose. This discussion also includes possible mitigation measures. Chapter 3. Affected Environment and Environmental Consequences: This section describes the environmental effects of implementing the proposed action and other alternatives. This analysis is organized by resource areas (i.e. rangeland, wildlife, botanical resources). Within each section, the effect of the No Action Alternative that provides a baseline for evaluation and comparison of the other alternatives that follow is described. Chapter 4. Consultation and Coordination: This section provides a list of preparers and agencies consulted during the development of the environmental assessment. Appendices. The appendices provide more detailed information to support the analyses presented in the environmental assessment. Additional documentation, including more detailed analyses of project area resources, data specific to the project, public notifications and their responses, and miscellaneous documentation, may be found in the project planning record located at the Whitman Ranger
