Hood National Forest is referred to as ‘the Forest’ in this document. This proposal contains a suite of projects including vegetation management, transportation management and aquatic/riparian management actions. The purposes of these actions are to enhance forest health, growth and diversity; improve critical habitat for northern spotted owls; enhance Late-Successional Reserves and Riparian Reserves; provide early- seral habitats; provide an appropriate road system that is safe, affordable and minimizes impacts to resources; and to enhance or restore streams, aquatic habitats and riparian vegetation. 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 section includes design criteria. 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 3 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 this 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 Project Area Summary The Hunter project area is located along the eastern edge of the Clackamas River Ranger District
