Preface This Watershed Analysis is presented as part of the Aquatic Conservation Strategy adopted for the President’s Plan (Record of Decision for Amendments to Forest Service and Bureau of Land Management Planning Documents within the Range of the Northern Spotted Owl, including Standards and Guidelines for Management of Habitat for Late- Successional and Old-Growth Related Species). This document follows the format provided in Part 2 of Ecosystem Analysis at the Watershed Scale: Federal Guide for Watershed Analysis - Version 2.2 (August 1995). This format consists of six steps: 1. Characterization of the watershed 2. Identification of issues and key questions 3. Description of current conditions 4. Description of reference conditions 5. Synthesis and interpretation of information 6. Recommendations This document is guided by two levels of analysis: • core topics - provide a broad, comprehensive understanding of the watershed. Core topics are provided in the Federal Guide for Watershed Analysis (8/95) to address basic ecological conditions, processes, and interactions at work in the watershed. • issues - focus the analysis on the main management questions to be addressed. Issues are those resource problems, concerns, or other factors upon which the analysis will be focused. Some of these issues prompted initiation of the analysis. Other issues were developed from public input in response to scoping or were identified by the team during the analysis process. Key analysis questions are developed for each issue. These questions are organized by analysis step to help focus the analysis and to provide organization to the document while addressing the issues.
