In California, RES has assembled a team of biologists, regulatory specialists, GIS analysts, and land conservation specialists with deep experience in Northern California, San Francisco Bay Area, Central Valley, Southern California, and Inland Desert regions.

The RES California team is experienced in all aspects of mitigation banking and species habitat preservation, and also draws from a deep bench of stream and river restoration expertise across the country for larger projects such as the mitigation plan for restoring the Klamath River, post-dam removal.
