RESEARCH INTERESTS

My research program at the Dixon Field Station focuses on the ecology of threatened and endangered species in a variety of ecosystems.  This includes primary ecological research on the endangered California Clapper Rail in SF Bay, the endangered San Francisco Gartersnake, the threatened Giant Gartersnake in the Central Valley of California, the California state-listed Greater Sandhill Crane, as well a the Greater Sage-Grouse, a sagebrush obligate bird species petitioned for listing under the Endangered Species Act.  My research has targeted studies which provide critical species information to land managers responsible for maintaining diverse and healthy wildlife populations while trying to help recover special status species. Understanding key life history traits of special status species can lead to management options promoting species recovery. 

My research team at Dixon employs a multi-disciplinary approach to all of our work including participation on several collaborative efforts.  We participated in the San Francisco Bay Goals Project beginning in 1995 and culminating in 2000 with a vision of the habitat needed to sustain healthy fish and wildlife populations in and around San Francisco Bay.  We are currently serving on the Great Basin Integrated Landscape Monitoring  (GBILM) Team for USGS to help link ecosystem drivers to on the ground monitoring programs. In addition, I am a co-investigator on a Sagebrush Ecosystem project examining the impacts of livestock grazing on sagebrush habitats in coordination with principal investigators from two other Science Centers. Bridging the gap between population biology and landscape level management is a primary goal of our research team’s effort.  Current animal handling permits include: California State Collecting Permit, Federal Banding Permit, Authorization to capture and mark the federally listed (threatened) giant garter snake and endangered California clapper rail in addition to other non-sensitive species. I have wide-ranging experience in radio-tagging numerous animals including snakes, waterfowl, shorebirds, and other migratory and non-migratory birds.
