Organized predator control

The predecessors of what is now known as the cooperative Texas Animal Damage Control Program have been involved in providing predatory animal control services for the last 80 years. This cooperative wildlife damage management agency is comprised of the Animal Damage Control Program of USDA’s Animal and Plant Health Inspection Service, the Texas Animal Damage Control Service of the Texas A&M University System, and the Texas Animal Damage Control Association.

One of the functions of the cooperative program is to conduct direct control operations for the protection of sheep and goats from depredation by coyotes and other predators. Historically, the program’s primary control strategy has been to attempt to prevent the infiltration of coyotes into the major sheep and goat production areas.
Extirpation of coyotes

The coyote and wolf take by county of the organized control program during fiscal year 1950 is reflected in Fig. 4. (Landon 1950). This categorized illustration of the number of animals taken per county provides a relatively representative picture of the re-establishment of coyotes into the Edwards Plateau when examined every tenth year. Those counties within the sheep and goat production areas which indicate no “take”, either had no program or had a program and did not take any coyotes. In either case, this usually indicated that few coyotes, if any, were present in those counties at that time.
