This report discloses the direct, indirect, and cumulative environmental effects that would result from the Proposed Action, the no‐action alternative and one action alternative developed to respond to issues raised during public scoping. This EA is released to provide notice to the public of the Proposed Action and alternatives, and to seek public comments. The document is organized as follows: Chapter 1, Introduction: This chapter includes information on the structure of the EA, location of the project, overview of the existing condition, the desired conditions, the purpose of and need for action, summary of the Proposed Action, applicable management direction, and the decision framework. This chapter describes public involvement, the issues identified during public scoping, and summarizes laws, regulations, and policies that are applicable to the proposed project. Chapter 2, Alternatives, Including the Proposed Action: This chapter provides descriptions of alternatives considered but dismissed from detailed analysis, the no‐action alternative, and the Forest Service’s Proposed

    BIOLOGICAL ASSESSMENT/EVALUATION, NON-NATIVE SPECIES RISK ASSESSMENT, WILDLIFE AND BOTANY REPORTS, and MANAGEMENT INDICATOR SPECIES EVALUATIONS for the MILLER CANYON OHV STAGING AREA Mountaintop Ranger District San Bernardino National Forest Prepared by: /s/ Deveree Kopp July 26, 2013 Deveree Kopp, Botanist Date Prepared by: /s/ Robin Eliason July 26, 2013 Robin Eliason, Wildlife Biologist Date SUMMARY This report addresses the potential effects of the proposed project on Threatened, Endangered, Sensitive, Watchlist, Management Indicator Species, and general vegetation and wildlife that are known or likely to occur at the Miller Canyon OHV staging area project. The purpose and need for the project is to reduce effects to riparian habitat, riparian-dependent species, and archaeological sites while providing a designated staging area for OHVs to access the associated green sticker trail system. The San Bernardino National Forest (SBNF) proposes to designate an official staging area on Forest Road 2N37 in Miller Canyon. This document assesses the potential effects associated with the proposed action, three alternatives, and the “no action” alternative. Because the proposed staging area alternatives would not be larger than the existing staging area, no change in use of the connected OHV trails (approximately 20 miles) would result from any of the proposed staging area sites. As such, this document will only analyze the potential effects of the staging areas themselves, not the OHV trail network connected to the staging area. Table 1 displays the known and potential occurrences of special status species in the project area and summarizes the “Determinations of Effects” for each. Federally-Listed Species and Critical Habitat The Miller Canyon project area contains suitable habitat for five Threatened/Endangered (T/E) animals: southwestern willow flycatcher, least Bell’s vireo, arroyo toad, California red-legged frog, and mountain yellow-legged frog.
