Hood National Forest, Oregon. The Mt. Hood National Forest proposes a thinning project in plantations ranging in age from 30 to 60 years old. The Mt. Hood National Forest is referred to as „the Forest‟ in this document. The purpose of this project is to increase the health and growth of trees and to enhance diversity within riparian reserves, late-successional reserves and matrix lands in the Collawash Watershed. Also, the purpose of this project is to provide forest products to the local economy. In order to achieve these objectives, this project proposes to thin second-growth plantations from approximately 2,053 acres. This acreage figure represents the sum of all of the plantations. It is estimated that approximately 1,588 acres would actually be thinned after accounting for stream protection buffers and other subtractions. The proposed action also includes road reconstruction and road decommissioning. Refer to section 1.3 for greater detail. Jazz Thinning page 3 1.0 INTRODUCTION 1.1 Document Structure The Forest Service has prepared this document in compliance with the National Environmental Policy Act (NEPA) and other relevant Federal and State laws and regulations. This document discloses the direct, indirect, and cumulative environmental impacts that would result from the proposed action and alternatives. This document uses a section number system. This paragraph for example is in section 1.1 and may be referred to as s. 1.1. The document is organized into the following parts: Summary Introduction: This section includes the purpose of and need for the project, and the agency‟s proposal for achieving that purpose and need. This discussion also includes design criteria and Best Management Practices. This section also details how the Forest Service informed the public of the proposal and how the public responded. Alternatives: This section provides a description of alternative methods for achieving the stated purpose. These alternatives are developed based on issues raised by the public and other agencies. Finally, this section provides a comparison of the environmental consequences associated with each alternative. Environmental Consequences: This section describes the environmental effects of implementing the proposed action and other alternatives. This analysis is organized by resource. Within each section, the existing situation is described first, followed by the effects of the alternatives. The no-action alternative provides a baseline for evaluation and comparison of the other alternatives. Consultation and Coordination: This section provides a list of preparers and agencies consulted during the development of the assessment. References and Appendices: The appendices provide more detailed information to support the analyses presented in the assessment. Additional documentation, including more detailed analyses of project-area resources, may be found in the project planning record located at the Estacada Ranger Station in Estacada, Oregon. 1.2 Background 1.2.1 Watershed Analysis Overview The Collawash/Hot Springs Watershed Analysis (1995) contains an in-depth discussion with maps, of the setting, the ecological processes, the resource conditions and the history of management. Additional maps are found in this document‟s Appendix A. The following is a brief summary of those topics with updates for related to the Jazz project. Jazz Thinning page 4 The proposed Jazz project area is located in the Collawash Watershed; a tributary of the Clackamas River. At one time the Hot Springs Fork of the Collawash River and the rest of the Collawash were considered a separate 5th field watersheds but they have since been combined. The watershed encompasses approximately 97,000 acres. It is on the west slope of the Cascade Mountain Range. The terrain is relatively
