John Karges

Associate Director of Field Science

As the man in charge of statewide biological inventories, John heads programs that catalog Texas natural history, conduct site assessments and archive biological information in databases for use in conservation planning and land stewardship. John’s professional specialties are vertebrate zoology, zoogeography and natural history, and in his role he works to tie those together with the large-scale conservation of special places in Texas. Prior to this role, he served in West Texas for nearly two decades as a land steward, conservation biologist, and regional program manager. A lifelong Texas resident, John grew up in Fort Worth, earned his BS from Texas A&I University in Kingsville and his master’s of science in biology from the University of Texas at Arlington. He has worked with the Natural History Museum of Los Angeles County and the Fort Worth Nature Center and Refuge, before joining The Nature Conservancy in California in 1990.
