Next, occurrence data will be collected for all focal species. Data sources for occurrence records will include but not be limited to: ^ CDFG Natural Diversity Database (NDDB) Rare Find GIS, latest edition available (Jones & Stokes subscription) ^ Vasco-Laughlin Resource Conservation Plan ^ North Livermore Specific Plan EIR ^ East Bay Regional Park District (EBRPD) survey data ^ SFPUC survey data ^ CNPS survey data not yet submitted to the NDDB ^ Survey data from local experts including university researchers Next, Jones & Stokes biologists will develop matrices that link land cover types with the habitat requirements of each of the focal species. These matrices will be used to develop up to 15 predictive models of species distribution across the study area where data allow. Additional parameters besides land cover will be used in these models such as elevation, slope, proximity to aquatic features, and other variables that can be used on a regional scale. These "expert opinion" models of habitat distribution have been used effectively in other regional conservation planning efforts adjacent to the study area. Their use has also been validated by independent scientists as appropriate for this scale of work. Deliverables: Preliminary draft and draft criteria for selecting focal species; draft list of candidate species; preliminary draft and draft list of focal species; draft map of focal species occurrence in the study area; up to 15 draft models predicting focal species distribution in the study area. Task 3. Compile Land Use and Open Space Data Another important component of the GIS database is a consistent and simplified land use designations layer. Land use designations show both existing and future planned development. By overlaying land use designations with land cover, Jones & Stokes can determine where new development will occur during the lifetime of current zoning and general plans. Jones & Stokes will develop a consistent land use classification scheme that is meaningful to the Conservation Strategy and integrates land use classifications of the different jurisdictions (Cities of Livermore, Dublin, Pleasanton, and Alameda County). Jones & Stokes will create a single land use designation map for the study area. This land use data layer will be based on existing GIS or CADD datasets. It is assumed that all CADD datasets will be in a real-world coordinate system (i.e., georeferenced) with attributes compatible with GIS. Jones & Stokes will also compile a GIS data layer of all protected lands (i.e., open space) in the study area. The initial data will come from the GreenInfo Network's dataset of open space from the Bay Area Open Space Council. Jones & Stokes will update and Eastern Alameda County Conservation Strategy August 2007 Scope of Work 5
