One of WRA’s legacy projects, the Callippe Golf Course and Preserve in Pleasanton, California, has again been recognized for environmental stewardship. The property has retained a status as a “Certified Audubon Cooperative Sanctuary” since 2006 as authorized through a program of Audubon International. Read a recent press release here.

Starting in 1999, WRA worked with the City of Pleasanton to develop an ecologically responsible 346-acre golf course and nature preserve located in the foothills above the Amador Valley. The site contains over five miles of restored streams, as well as habitat for the federally endangered Callippe silverspot butterfly and federally threatened California tiger salamander and California red­legged frog. Following its opening in 2005, WRA conducted annual monitoring of both the mitigation and conservation areas for 10 years.

As a result, the created, restored, and enhanced riparian areas have exceeded all performance criteria outlined by the regulatory agencies including the U.S. Army Corps of Engineers, Regional Water Quality Control Board, and California Department of Fish and Wildlife. Most importantly, the original native plantings have proven to be self-sustaining, with an understory comprised primarily of native plant recruits. In addition, Johnny jump-up, the host plant for the Callippe silverspot butterfly, has increased in population density within the surrounding Preserve.
