Scope of Work <br />The preliminary work program for the Eastern Alameda County Conservation Strategy <br />(Conservation Strategy) developed by Jones & Stokes includes seven tasks. These seven <br />tasks are split into three project phases as shown below to facilitate a phased budget. <br />^ Task 1. Map Land Cover (Phase 1) <br />^ Task 2. Map Focal Species (Phase 1) <br />^ Task 3. Compile Land Use and Open Space Data (Phase 1) <br />^ Task 4: Conduct Conservation Gap and Corridor Analysis (Phase 2) <br />^ Task 5: Develop Conservation Goals (Phase 2) <br />^ Task 6: Develop Conservation Priorities (Phase 2) <br />^ Task 7: Prepare Draft and Final Conservation Strategy Report (Phase 3) <br />^ Task 8: Project Management and Meetings (all Phases) <br />Phase 1 is generally the data collection phase. Phase 2 is generally the data analysis <br />phase. And Phase 3 is the final phase in which the draft Conservation Strategy is <br />developed and released for public review and comment, and then a final document is <br />produced. This scope of work addresses work only in Phase 1 (Tasks 1, 2, 3, and 8). <br />Work Tasks <br />Task 1. Map Land Cover <br />Under this task, Jones & Stokes biologists and GIS specialists will develop a GIS land <br />cover database of the study area using ortho-rectified color aerial photography as the base <br />source of information. Jones & Stokes botanists would delineate vegetation and other <br />land cover types based on interpretation of aerial photograph signatures. This mapping <br />will be conducted by digitizing polygon boundaries directly to the GIS through a "heads- <br />up" on-screen approach. Alameda County has May 2006 aerial photography in digital <br />form (6" resolution in urban areas, 1-2-foot resolution in rural areas) that cover 100% of <br />the study area. Jones & Stokes will use the County's air photos for the land cover <br />mapping <br />Automated photo-interpretation packages exist that delineate polygons. However, Jones <br />& Stokes has found that such systems are not sufficiently accurate to be effective with the <br />vegetation and other land cover types found in Alameda County (e.g. serpentine <br />grassland, seasonal wetlands, chaparral, and rural residential development are not likely <br />to be distinguishable from other land cover types by these programs). <br />Eastern Alameda County Conservation Strategy August 2007 <br />Scope of Work 2 <br />
