Description: We ranked the biodiversity conservation values of the study area into high, moderate, and low classes. Class designation was based on the objectives of the assessment, data availability for the study area, and data quality. We used San Joaquin kit fox as an umbrella or representative species for a suite of San Joaquin Valley threatened, endangered, and sensitive species including giant kangaroo rat and blunt-nosed leopard lizard. Expert review confirmed that by using kit fox habitat suitability, permeability, and recovery data we would capture most of the species of interest in the study area. We designated moderate biodiversity conservation value areas based on the presence of 1) United State Fish & Wildlife Service kit fox satellite and linkage recovery areas, 2) Audubon Important Bird Areas, 3) The Nature Conservancy’s portfolio conservation areas, 4) serpentine soils, 5) California Rangeland Conservation Coalition “essential” areas for rangeland conservation, and 6) compatible agricultural crops for shorebirds and waterfowl within three kilometers of designated valley floor protected areas or easements. We dissolved each of the following datasets together to create a single moderate biodiversity conservation value layer. The report that describes the methods, assumptions and processing of data to generate this feacture class is: Butterfield, H.S., D. Cameron, E. Brand, M. Webb, E. Forsburg, M. Kramer, E. O’Donoghue, and L. Crane. 2013. Western San Joaquin Valley least conflict solar assessment. Unpublished report. The Nature Conservancy, San Francisco, California. 26 pages. The objective of this assessment is to characterize the land use and conservation constraints and opportunities associated with siting solar energy facilities in the Western San Joaquin Valley. This approach identifies areas with high conservation value that are important to avoid when planning energy infrastructure, as well as areas of lower environmental conflict potentially suitable for development. While the approach we take focuses on refining the conservation values in the study area, we also classify the region’s agricultural resources using simple, broadly applicable classes to begin to assess trade-offs or synergies between agricultural production, habitat conservation and energy development. In our assessment of biodiversity conservation values, we focus on core and high quality habitat for multiple listed species, including kit fox, and emphasize the preservation of connectivity for kit fox and other wide-ranging species. This analysis is meant to be a first initial screen on values to consider when planning facilities, it is not meant to determine permitting or regulatory processes.
