Wild Rogue - South Watershed Analysis WILD ROGUE - SOUTH WATERSHED ANALYSIS REO Fifth Field Watershed #1710031004 Rogue River/Kelsey Creek (Portion South of the Rogue River) March 2000 U.S. Department of the Interior Bureau of Land Management Medford District Grants Pass Resource Area Version 1.0 - March 2000 Wild Rogue - South Watershed Analysis March 2000 Dear Reader: The purpose of this watershed analysis is to identify the various ecosystem components in the Wild Rogue - South Watershed and their interactions at a landscape scale. The analysis looks at historical ecological components, current ecological components, and trends. It makes recommendations for future management actions that could be implemented to reach certain ecological conditions. The watershed that is being analyzed in this document is the Wild Rogue - South. This watershed is the southern half (south of the Rogue River) of the Rogue Kelsey fifth field watershed (REO Watershed #1710031004). The northern half is analyzed in the Wild Rogue - North Watershed Analysis. As you read this document, it is important to keep in mind that the watershed analysis process is an iterative process. As new information becomes available it will be included and periodic updating will occur. It is also important to keep in mind that this analysis document is not a decision document. The recommendations that are included are a point of departure for project-specific planning and evaluation work. Project planning then includes the preparation of environmental assessments and formal decision records as required by the National Environmental Policy Act (NEPA). Project planning and land management actions would also be designed to meet the objectives and directives of our Medford District Resource Management Plan (RMP). This watershed analysis will thus be one of many tools in land management planning and project implementation within the Wild Rogue - South Watershed on Bureau of Land Management (BLM) administered lands. Although ecological information, discussions and recommendations are presented at the landscape scale irrespective of administrative ownership, please understand that the BLM will only be implementing management actions on the lands it administers. Preparation of the watershed analysis follows the format outlined in the draft federal watershed analysis guidelines in the document entitled Ecosystem Analysis at the Watershed Scale: Federal Guide for Watershed Analysis (Version 2.2, August 1995). If you have additional resource or social information that would contribute to our better understanding the ecological and social processes within the watershed, we would appreciate hearing about them.
