■ estimate the potential for algal blooms, mosquito production, or water quality conditions detrimental to aquatic wildlife; and ■ recommend management measures to minimize or eliminate water quality impacts and identify any impacts that cannot reasonably be mitigated. CHAPTER 11. BIOLOGICAL RESOURCES The biological resources analysis will present information about the vegetation, wildlife, and aquatic resources on and near the project site. Issues relating specifically to the proposed habitat management plan will be addressed in Chapter 12, "Habitat Restoration". No wetland delineation surveys are proposed in this scope of work because we assume the wetland delineation performed by Sugnet and Associates will have met this need. Also, we are not including a habitat evaluation procedures (HEP) analysis in our scope of work. We will, however, meet with USFWS and DFG staff to discuss our study and impact assessment methodologies and, if at that time the county deems that a HEP analysis is appropriate, we will prepare a contract augmentation. Vegetation and Wildlife Resources The dominant vegetation on the property consists of a large oak-buckeye savanna, several vernal pools, a closed-canopy oak forest along the Mokelumne River and riparian vegetation along the margins of the ephemeral Tracy Lake. The oak forest along the Mokelumne River is the largest remnant riparian forest in San Joaquin County. The site provides habitat for a diverse population of wildlife including invertebrates, raptors, waterfowl, and mammals. A preliminary list of special-status plant species with potential to occur in the project area includes California hibiscus (Hibiscus californica), Mason's liliopsis (Liliopsis masonii), Sanford's arrowweed (Sagittaria sanfordii), Boggs Lake hedge-hyssop (Gratiola heterosepala), and Ahart's dwarf rush (Juncos leiospermus var. ahartii). A preliminary list of special-status wildlife with potential to occur in the project area include: vernal pool fairy shrimp (Branchinecta lynchi), California linderiella fairy shrimp (Linderiella occidentalis), valley elderberry longhorn beetle (Desmocerus califomicus dimorphus), California tiger salamander (Ambystoma tigrinum californiense), giant garter snake(Thamnophis couchi gigas),greater sandhill crane(Gnus canadensis tabida), Swainson's hawk (Buteo swainsoni), black-shouldered kite (Ehmus caeruleus), northern harrier (Circus cyaneus), burrowing owl (Athene cunicularia), yellow warbler (Dendroica petechia), and tricolored blackbird (Agelaius tricolor).
