READER’S GUIDE

This Draft Supplemental Environmental Impact Statement (DSEIS) contains supplemental 

information about proposed use and resulting environmental effects associated with Motorized 

Vehicle Use on the Rogue River-Siskiyou National Forest. 

The purpose for supplementing the Final Environmental Impact Statement (FEIS) dated December 

3, 2009, is to clarify issues, expand on analyses, and provide additions, changes and corrections 

that are responsive to issues brought forth from administrative appeals of the FEIS. 

This DSEIS analysis supplements, is tiered to, and incorporates by reference the Administrative 

Record for the 2009 FEIS and its Record of Decision (ROD) for Motorized Vehicle Use on the Rogue 

River-Siskiyou National Forest. 

Understanding the structure of this DSEIS document is important to an overall understanding of the 

information presented in this supplement. Edits were completed throughout this document to 

provide clarification of information previously presented. All modifications, clarifications, or additions 

for each section will be framed within a box. Other minor corrections, explanations and edits have 

also been made. This document is designed to supplement the existing 2009 FEIS document by 

adding information and analysis to Chapter I (Purpose and Need), Chapter II (Alternatives), and 

Chapter III (Affected Environment and Environmental Consequences). In some cases (as noted), it 

will replace certain sections of these FEIS chapters. This supplemental process will then allow the 

latest and most complete information and analysis to include the 2009 FEIS concurrent and 

integrated with the 2011 supplemental information and analysis. 

The following provides an overview of the components of this document. 

Summary: The summary included in this DSEIS provides a concise overview of the analysis 

process, information, and consequence analyses presented in the complete text the document. The 

format for this Summary is adapted from “Eight NEPA Questions” (8 questions any EA or EIS should 

readily answer), developed by Owen L. Schmidt, Attorney, formerly with USDA, OGC Portland OR. 

Table of Contents: A table of contents is presented at the beginning of the document. It includes 

specific page reference to the primary Chapters of the EIS and to three levels into the outline 

structure of these Chapters. Lists of maps, tables, figures, and the contents of the appendices are 

also included in the Table of Contents. 

Chapter I - Purpose and Need: Chapter I provides a background to the proposal and the Travel 

Management Rule, describes the Purpose and Need for the proposal, and the scope of analysis. It 

briefly describes the Proposed Action and identifies the decision framework. A summary of 

applicable management direction is also provided. The final sections describe Scoping and other 

public involvement activities, identification of issues, including Significant, Other, and Out of Scope 

Issues. 

Chapter II - Alternatives: Chapter II includes a description of the alternative development process, 

describes alternatives considered in detail, including Alternative 1-No Action, which represents the 

current condition. The Action Alternatives are comprised of: Alternative 2, would designate the 

current condition, excluding cross-country travel, with Plan Amendments be consistent with the 

Travel Management Rule, and enact site-specific route Plan Amendments to make current use 

consistent with the Forest Plans; Alternative 3, the Proposed Action, based on the Forest’s Travel 

Analysis process, and aims to strike a balance for various forms of motorized use; it would also 

implement the Travel Management Rule with Plan Amendments; Alternative 4 addresses the 

significant resource issues identified in Chapter I through some reduction in motorized use over 

current conditions; and Alternative 5, which combines elements from Alternatives 3 and 4. 

Alternative 5 was developed as a result of the analysis in the DEIS and public comments. 

 
Each alternative considered in detail is presented, including function and description, as well as 

District- and Forest-specific elements where appropriate. Mitigation measures, monitoring 

requirements, and an implementation strategy for the Action Alternatives are also discussed. The 

final section presents a comparison of alternatives, in a table format, of the components contained 

within alternatives, the alternative’s response to the Significant Issues (i.e., environmental 

consequences), and the alternative’s response to Other Issues. 

Chapter III - Affected Environment and Environmental Consequences: Chapter III describes 

the current physical, biological, and human social, and economic conditions within the area of 

influence of the Alternatives Considered in Detail (organized by and referred to in terms of the 

various Significant and Other Issues, as described in Chapter I). Also described is attainment of 

Purpose and Need. This information provides the baseline for assessing and comparing the 

potential consequences of the Action Alternatives, and No Action. 

Chapter IV - References: This chapter of the document provides a list of sources of information, 

literature and data used to prepare this EIS. 

Chapter V - List of Preparers and Contributors: Chapter V provides a summary of the 

responsibilities for project leadership, and resource specialists with input into the preparation of this 

EIS and other agency personnel who provided data, review, and/or information. 

Chapter VI - List of Agencies and Organizations to Whom Copies of the Statement Are Sent: 

Chapter VI contains the names of the agencies, organizations, and individuals who were provided 

copies of the EIS. 

Glossary: Definitions of key or technical words used in the EIS are included in a section that follows 

Chapter VI. 

Appendices: Seven appendices are included with the DSEIS. They contain technical and support 

information that is important to understanding the process and analysis: APPENDIX A is reserved 

for responses to substantive comments received during this DSEIS comment period; APPENDIX B

summarizes Forest Plan direction for motorized use and contains detail on proposed Forest Plan 

Amendments; APPENDIX C contains terrestrial wildlife species accounts, APPENDIX D summarizes 

watershed, hydrologic and soils characteristics, APPENDIX E contains a compilation of current 

Forest Orders, APPENDIX F contains a Port-Orford cedar risk key, and APPENDIX G contains 

aquatics and fisheries species accounts.
