Tom Cahill - A Legacy of Nature

Tom and Ginny Cahill found a way to protect the land they love and support science. The couple donated two hundred spectacular acres of creekside and oak woodland habitat to the UC Davis Natural Reserve System.  They also established an endowment to ensure responsible stewardship of the land into the future.  The Cahill Riparian Preserve is serving as a research and teaching refuge, a quiet complement to nearby Stebbins Cold Canyon, with its steady stream of hikers.

In addition to their gifts, the couple tirelessly served on the statewide Board of Councilors to the University of California Natural Reserve System, raising awareness throughout the region and state of the vital roles of land protection and science in natural settings.

Tom passed away May 1, 2019. His energy and enthusiasm, always evident as he led countless visitors on tours to the Cahill Riparian Preserve, will be sorely missed. The legacy of land conservation and science that he and Ginny have created is a fitting tribute to a distinguished scholar and individual.
