Introduction
This chapter presents the environmental consequences for the alternatives analyzed in this draft supplemental EIS for the Sierra Nevada Forest Plan Amendment. Information in this chapter addresses aspects of the environment likely to be affected by the management actions proposed in the alternatives. This chapter describes the scientific and analytical basis for the summary comparison of the effects of the alternatives presented at the end of Chapter 2.
The environmental consequences sections in the SNFPA FEIS were reviewed to assess whether new information and/or proposed management changes could change the effects analyses previously conducted for the SNFPA FEIS. Various aspects of the biological, physical, and social environment would not be affected differently by either new information or proposed management changes from those effects previously disclosed in the SNFPA FEIS; therefore, these topics were not further analyzed in this supplement. Appendix C "Consistency Review of Documentation for the Sierra Nevada Forest Plan Amendment" provides the rationale for not further analyzing specific topics in this Draft SEIS.
Parts 4.2 through 4.5 of this chapter focus on the environmental consequences associated with Alternatives S1 and S2. Part 4.6 briefly describes the environmental consequences for Alternatives S3 and F2 through F8. Detailed analyses of environmental consequences for Alternatives F2 through F8 are presented in the SNFPA FEIS, Volumes 2 and 3. The information presented in this document for these alternatives (F2 through F8) addresses aspects of environmental consequences that have changed based on new information identified during the SNFPA review process.
