This project is located on the Wild Rivers Ranger District of the Rogue River-Siskiyou National Forest. This Biological Evaluation and specialist report discloses the existing conditions for late successional reserve and special status wildlife species and anticipated direct, indirect, and cumulative environmental effects that would result from the Project proposed action and alternatives. The document is organized into the following parts: Project Description: This section describes the project location, purpose and need and action alternatives. Regulatory Setting and Methodology: This section summarizes regulations regarding project analysis for special status species, metrics or environmental indicators used to conduct the analysis, and desired conditions (as appropriate). Affected Environment and Environmental Consequences: This section presents existing conditions and environmental effects of implementing the proposed action and alternatives. The effects of the No-Action Alternative are described first to provide a baseline for evaluation and comparison of other alternatives that follow. Consultation and Coordination: This section provides a list of preparers and agencies consulted during the development of this document. References: This section lists bibliographical information of any literature cited and personal communications used to write this report. Appendices: The appendices provide more detailed information to support the analyses presented in the report. Proposed Project Location The Project is located in Del Norte County in California, approximately 12 miles upstream of Cave Junction, Oregon, where it joins the West Fork Illinois River before proceeding to the Pacific Ocean via the Rogue River. The legal description of the project area includes the stream channels of Dunn Creek and the East Fork Illinois River in T. 19 N., R. 5 E., Sections 33, 34, 35 and T. 18 N., R. 5 E., Sections 1, 2, 3, 4, 12 of the Humboldt Meridian (Appendix A, Map 1). Dunn Creek and Upper East Fork Illinois River 6th field subwatersheds (26,828 acres, Appendix A, Map 2) located within the East Fork Illinois River 5th field watershed (57,779 acres), which makes up 9 percent of the 628,000 acre Illinois River subbasin within the Southern Oregon Coastal Basin, which has been identified by the Forest Service Pacific Northwest Region as a priority basin. 1 East Fork Illinois River Channel and Floodplain Restoration Project, Wildlife BE and Specialist Report Approximately 64% of the East Fork Illinois River watershed is lands managed by the Rogue River-Siskiyou National Forest, 9% managed by the BLM and the remaining 27% under mixed private ownership including portions of the city of Cave Junction and the town of Takilma (USDA Forest Service and USDI BLM, 2000). A Watershed Restoration Action Plan (WRAP) was completed for the East Fork Illinois River watershed in 2014. The WRAP identified priority aquatic restoration projects within the watershed for the improvement and recovery of water quality, fish habitat, and riparian forest conditions with an interdisciplinary and partnership approach. The East Fork Illinois River watershed consists of three subwatersheds: Lower East Fork Illinois River, Upper East Fork Illinois River, and Dunn Creek. Dunn Creek was determined to be a priority subwatershed for the following reasons: It provides critical habitat for an independent population of Southern Oregon/Northern California Coast Coho Salmon, a threatened species under the Endangered Species Act. The East Fork Illinois River is listed as water quality limited for summer water temperatures under section 303(d) of the Clean Water Act, and improving stream shade in Dunn Creek will decrease temperatures of the water flowing into the East Fork Illinois River. The East Fork Illinois River is a primary contributor to the Illinois River basin salmonid population. About 40 percent of the Rogue River basin coho production may come from the Illinois River.
