Working closely with the Williamson County Conservation Foundation, the U.S. Fish and Wildlife Service and various local stakeholders Dr. White co-authored the Wilco RHCP in support of an Endangered Species Act 10(a) permit for incidental take of two endangered songbirds, and two endangered karst invertebrates, the Bone Cave harvestman and Coffin Cave mold beetle. Following approval in 2008, the RHCP has evolved into one of the most successful RHCPs in the country. It has served as the primary mitigation vehicle for many Williamson County Road Bond projects including improvements to IH-35, SH 195, Ronald Reagan Blvd., R.M. 620, O’Connor Road, and many others. Cambrian continues to provide implementation services on RHCP preserves including biological monitoring of dozens of caves containing endangered karst invertebrates and several springs on RHCP preserve land containing the threatened Georgetown, Salado, and Jollyville Plateau Salamanders.
