Bill Sheffield

San Antonio | Biologist

Dr. Sheffield was a biologist who worked as a wildlife consultant and land manager for large private landowners, such as Humble Oil, and as a scientist for governmental agencies, including Texas Parks and Wildlife, the Alabama Department of Conservation and Natural Resources, and the U.S. Fish and Wildlife Service. He was particularly well-known for his research and writing on the history and ecological role of exotic wildlife, as outlined in the books, “Nilgai Antelope in Texas” (1983), and “Exotics on the Range” (1994), co-written with Elizabeth Mungall. Axis deer, sika deer, fallow deer, Indian blackbuck, nilgai antelope, mouflon-type sheep, aoudad, and wild boar are some of the non-native species that are well-established in Texas, occur in over half of the state’s counties, and number more than 165,000 individuals.
