INTRODUCTION The purpose of this biological assessment/biological evaluation (BA) is to determine the effects of the High Bar Placer Phase 2 Project on wildlife and fisheries species listed as Endangered, Threatened, or Proposed under the Endangered Species Act; on designated Critical Habitat for those species; and on species listed as Sensitive by the Pacific Southwest Region, USDA Forest Service. This BA is prepared in accordance with the legal requirements set forth under Section 7 of the Endangered Species Act of 1973, as amended [16 U.S.C. 1536 (c) et seq. 50CFR 402] (ESA), and follows the standards established in the Forest Service Manual direction (FSM 2672.42; USDA Forest Service 1991). The list (dated: October 25, 2010) of federally listed species was obtained online at http://arcata.fws.gov/specieslist (reference #792457677-142616) (USDI 2010). This BA addresses the following species from those lists: Threatened Northern spotted owl (Strix occidentalis caurina)1 Marbled murrelet (Brachyramphus marmorata)2 Candidate Western Yellow-billed Cuckoo (Coccyzus americanus) Pacific Fisher (Martes pennanti) Sensitive Bald eagle (Haliaeetus leucocephalus leucocephalus) Peregrine falcon (Falco peregrinus anatum) Northern goshawk (Accipter gentiles) Great gray owl (Strix nebulosa) Swainson's hawk (Buteo swainsoni) Willow flycatcher (Empidonax trailii) Greater sandhill crane (Grus canadensis tabida) California wolverine (Gulo gulo luteus) 'The U.S. Fish and Wildlife Service (USFWS) designated Critical Habitat for the northern spotted owl (NSO) on January 15, 1992. 2 Critical Habitat for the marbled murrelet was designated by the USFWS on May 24, 1996. 2 High Bar Placer Mine Phase 2 BA/BE Pacific fisher (Martes pennanti pacifica) American marten (Martes americana) Sierra Nevada red fox (Vulpes vulpes necator) Pallid bat (Antrozous pallidus) Townsend's big-eared bat (Corynorhinus townsendii) Northwestern pond turtle (Emys marmorata marmorata) Foothill yellow-legged frog (Rana boylii) Cascade frog (Rana cascade) Southern torrent salamander (Rhyacotriton variegates) Siskiyou Mountain salamander (Plethodon stormi) Blue-gray taildropper slug (Prophysaon coeruleum) Tehama chaparral snail (Trilobopsis tehamana) The High Bar Placer Phase 2 Project does not occur in designated Critical Habitat for the Northern Spotted Owl. Species Excluded from Further Documentation The High Bar Placer Phase 2 Project is not within the range of the marbled murrelet (coastal forests) and no designated Critical Habitat for this species occurs at the project site. This species will not be addressed further in this document. The High Bar Placer Phase 2 Project is not within the range of the Sierra Nevada red fox (Cascades Mountains and Sierran Crest) or the southern torrent salamander (streams within coastal forests). These species will not be addressed further in this document. Habitat for the Great Gray Owl (pine and fir forests adjacent to montane meadows), Swainson's hawk (perennial grassland, grassy shrub-steppe, or agricultural landscapes), and greater sandhill crane (wetlands, marshes, grasslands, or irrigated fields) does not occur in the project area. These species will not be addressed further in this document. CONSULTATION TO DATE For this No Effect BA, this consultation to date sections does not apply. HABITAT FIELD REVIEW AND MAPPING Northern Spotted Owl Northern spotted owl (NSO) habitat field reviews were conducted by Klamath National Forest wildlife biologist Sam Cuenca in April 2009. Field notes are available at the wildlife office of the Salmon/Scott River Ranger District Office. Field reviews were conducted to verify the presence/absence of NSO habitat in and adjacent to the project area. 3 High Bar Placer Mine Phase 2 BA/BE Mapping data delineated the project site as falling within mid-seral forest vegetation and NSO foraging habitat. Field reviews verified that the project site is located in mid-seral habitat, but that this area had been burned by forest fires in the late 1970s resulting in a brush field bounded by plantations and mid- seral timber stands. CURRENT MANAGEMENT DIRECTION Programmatic management direction for the Forest is provided by the Klamath Land and Resource Management Plan (Forest Plan, 1995), which incorporates direction in the Record of Decision for Amendments to the Forest Service and Bureau of Land Management Planning Documents within the Range of the NSO (1994). The Forest Plan was developed utilizing the guidelines provided by the Forest and Rangeland Renewable Resource Planning Act of 1974, as amended by the National Forest Management Act of 1976, and the National Environmental Policy Act of 1976. The Klamath National Forest is divided into 17 management areas (land allocations), each with distinct management direction that has been developed in response to Forest resource opportunities and public issues. Activities proposed as part of the High Bar Placer Phase 2 Project would occur in two land allocations, in accordance with Forest Plan direction, as follows: Partial Retention Visual Quality Objective and Riparian Reserves. DESCRIPTION OF THE PROPOSED ACTION The High Bar Placer Phase 2 Project has been proposed to provide extraction of gold deposits on National Forest System lands. PROJECT AREA "Action area" is defined for ESA purposes as "all areas to be affected directly or indirectly by the Federal action and not merely the immediate area involved in the action" (50 CFR 402). In this document the term "analysis area" is synonymous with "action area." The analysis area described in this analysis was determined based on the distribution of effects relative to the wildlife species listed on page one. Based on field review and consideration of direct and indirect effects, the project area is defined as: the area directly affected by vegetation removal activities, soil excavation, gold milling operations, water drafting, and the area potentially affected by noise disturbance from those activities (up to 0.25 miles from noise generating equipment, depending on topographic features that may limit noise). The project area encompasses approximately 4 acres and is located on the Salmon/Scott River Ranger District approximately 51 miles southwest of Fort Jones, Siskiyou County, California, Township 10 North, Range 7 East, Section 24 Humboldt Meridian. The current condition, reference condition, and desired condition of the project area have been assessed in the Lower South Fork of the Salmon River Ecosystem Analysis (USDA Forest Service 1997), and copies of this analysis are available at the Salmon/Scott River Ranger District office. Activities that are proposed as part of the High Bar Placer Phase 2 Project will be assessed for their direct, indirect and cumulative effects on the ability of individual animals of a species to breed, feed or shelter within the project area. PRIMARY ELEMENTS OF THE PROJECT 4 High Bar Placer Mine Phase 2 BA/BE Road Actions An existing non-system road is currently used for mine exploration. Access in the project area will use this existing road for transport of excavated material to the milling area on-site. Use of road will be by pickup truck, excavator and 10-yard dump trucks. Upon termination of the operations the road will be closed. McNeal Creek Road (a Forest Service system road, open to the public year-round) will be used to access the mining operations. Vegetation Removal Vegetation in the Phase 2 area is dominated by brush (Manzanita, deer brush, honeysuckle, poison oak, gooseberry and mock orange), with a minor amount of Douglas-fir, madrone, and knobcone pine. Approximately six (6) merchantable Douglas-fir trees (12-18 inches DBH) are proposed for removal and will be used on-site for mining purposes. Vegetation will be removed by cutting with chainsaws, loading the brush onto a dump truck and hauling it to a disposal location near McNeal Creek Road. Brush will be piled and burned as directed by the Forest Service. Timber will also be cut by chainsaws and used in log form for cribbing, bunk logs and other mine related uses. If timber removed is not needed for mining purposes, the logs will be decked (at a location identified by the Forest Service) for disposal by the Forest Service. Vegetation will be removed from approximately 1.75 acres for the mine site and milling operations. Vegetation removal will be accomplished in stages over the life of the mine plan when necessary to remove overburden and access placer deposits. Brush removal at stockpile areas and mill site will occur over an approximately 2 week period. Overburden Soil Removal & Mining The Phase 2 area has approximately 19,000 cubic yards of overburden soil material that will need to be removed to gain access to placer deposits. Overburden is soil that is has no valuable mineral deposit or has a deposit in such low quantities that it is not considered viable to extract. This material will be excavated from the site in a step/bench cut manner to minimize surface disturbance and reduce handling the material multiple times. Overburden excavation will be accomplished by cutting strips or "blocks" from the area; each block is approximately 200 feet in length by 40 feet wide to a depth ranging between 6 and 20 feet to the placer deposit (depth will vary based on bedrock locations). Refer to Drawing 1 for overburden stockpile location. The stockpile will be stabilized prior to the wet weather season (October 15). Stabilization may be accomplished by various methods, and will be dependent on the volume of material at the stockpile site.
