A final supplemental environmental impact statement (FSEIS) has been prepared to further review the project alternatives and analysis, to correct and update information that was presented in the Final Environmental Impact Statement (FEIS), and to consider information that became available since the FEIS was published in September 2015.The project area comprises 43,731 acres of National Forest System lands within the Clear Creek drainage, located approximately 5 air miles southeast of Kooskia, Idaho. This project proposes timber harvest, commercial thinning, precommercial thinning, prescribed fire, reforestation, native grass restoration, and road system improvements to achieve desired age class and species distributions and to improve watershed health. The FEIS (September 2015) analyzed a total of four alternatives, including a No Action Alternative. All alternatives (except for Alternative C) remain the same as in the 2015 FEIS. The alternatives are discussed in depth within the body of this document and the September 2015 FEIS. Activities common to all action alternatives: 41 acres of grass restoration, 1,371 acres of prescribed fire, 1,887 acres of precommercial thinning, 119.8 miles of system road reconstruction, 48.8 miles of system road reconditioning, 13.2 miles of system road decommissioning, and two site specific Forest Plan amendments adopting the Region 1 soil standard of 15% for detrimentally disturbed soils, and clarifying the definition of old growth found in Appendix N of the Nez Perce Forest Plan
