that blunt-nosed leopard lizards occupy the permit area. However, the active work areas are accessible from adjacent habitat. Therefore, if any blunt-nosed leopard lizards were to enter the work area from adjacent habitat, the individuals could be subject to impacts from vehicles and activities occurring within the permit area. However, with implementation of the recommended mitigation measures, the proposed Project is not likely to result in take of this species, and potential impacts would be less than significant. San Joaquin Antelope Squirrel(Ammosphermophilus nelsons) No antelope squirrels were observed during reconnaissance surveys conducted by McCormick Biological, Inc. either in 2003, or 2004. Habitat modification, including land leveling, excavation, and grading associated with mining and disposal facilities, has significantly affected habitat quality for antelope squirrel within the permit area. Small mammal burrow density was extremely low in the permit area and no San Joaquin antelope squirrels or their sign were observed during the field survey. Given the result of the survey in combination with the implementation of recommended mitigation measures listed above,the potential for direct impacts to this species would be less than significant. San Joaquin Kit Fox(Vulpes macrotis mutica) The San Joaquin kit fox is listed as a federally endangered and a state threatened species. During the survey six potential kit fox dens were observed in the"Additional Marshalling and Stockpiling Area" (see Figure 4.2-2). In addition, one of the burrowing owl burrows observed within Pit "G" was also a potential kit fox den. Although portions of the permit area represent suitable habitat for San Joaquin kit fox, there was no evidence of use by this species observed during reconnaissance survey. San Joaquin kit fox are likely to forage in the vicinity of the permit area and may use den sites in the future. With implementation of appropriate avoidance measures discussed above, the potential for direct impacts to this species would be less than significant. Burrowing Owl(Athene cunicularia) Burrowing owl (Athene cunicularia) is a California species of special concern and federal species of concern. Two active burrowing owl burrows were observed in the area identified as Pit "G." One burrowing owl was observed leaving a burrow and another was observed in the vicinity of another burrow. Additionally, five burrowing owl burrows were observed within the"Additional Marshalling and Stockpiling Area" and one other burrow with burrowing owl sign was observed near the "Active" burrowing owl burrows in Pit"G" (see Figure 4.2-2). Impacts to individual burrowing owls that may occupy or forage through the Project area could include injury and mortality as a result of Project vehicle traffic and hazards to wildlife that occur as a result of construction activities. However, with implementation of appropriate avoidance measures as discussed above, the potential for direct impacts to this species would be less than significant. Loggerhead shrike(Lanius ludovicianus) No observations were made during the reconnaissance survey. The Project site contains a small amount of suitable nesting habitat for this species in the shrubby low area on the central east side of the Project site and the open areas are suitable foraging habitat. However, with the implementation of the recommendations described above, impacts to this species are not anticipated. Horned Lark(Eremophilus alpestris actia) The California horned lark is listed as a state species of concern. No observations of this species or their — .._.... ---------- ---- -- ----------- --------- --- Findings of Fact—Section 15091 March 15,2016 H.M.
