The source of this coverage data set is the fish biodiversity maps created for The Nature Conservancy (TNC) as part of their Hexagon Project. Professor Peter Moyle and his graduate student, Paul Randall, of the Department of Wildlife and Fisheries Conservation Biology at the University of California, Davis were hired to produce range maps for all known fish species that presently occur in California. Each coverage denotes a separate fish species (refer to the species coverage key below). The polygons are estimated to be accurate at a scale of roughly 1:1,000,000.

Survey data was integrated within a GIS by georeferencing observations to an existing national spatial framework (National Hydrography Dataset), which allows for broader transferability to watersheds shared with neighboring states, creating a seamless layer not limited by state boundaries. Addressing the management and conservation challenges for native fishes will require the ability to “data mine” the extensive existing information on distribution and abundance of species available from aquatic survey programs. Results from such syntheses can be used to assess the current conservation status of native fishes, quantify the extent of species invasions, and establish baseline distributions with which to evaluate...
