Keeler-Wolf, T., D.R. Elam, K. Lewis and S.A. Flint. 1998. California Vernal Pool Assessment Preliminary Report (1998) (3.21MB pdf)
A summary of the current statewide body of knowledge for vernal pools. The vernal pool regions identified in the report accentuate the variety of distinct natural resources encompassed in California vernal pools: the rare and endemic plants and animals, the variety of vernal pool types, and the relationship of geography to these factors. Division of the state into vernal pool regions can also enable us to understand the widely varying management concerns for the state's pools.

California Central Valley Wetlands and Riparian GIS Data Sets (163MB zip)
Raster data set of wetlands, riparian woody areas, and surrounding landcover in three key regions: 1) the Sacramento Valley, 2) the San Francisco Bay/Delta, and 3) the San Joaquin Valley.
