Coyotes and Cattle

Coyotes are a common predator on ranching operations in south Texas. However, little is known about what motivates coyote space use in ranching operations. Common ranching practices may unknowingly place calves and deer fawns at risk of predation. Sound coyote management on south Texas ranches depends on understanding coyote behavior.

East Foundation and its large, unmanaged coyote population on the San Antonio Viejo Ranch present the opportunity to provide data on coyote behavior and predation risks. These include information on:

  • Coyote social dynamics – territorial versus transient animals
  • Territory turnover or change over time
  • Long distance movements of transient animals
  • Movements relative to livestock management practices

The goal is to address the following questions:

  • How do common wildlife and livestock management practices impact coyote behavior on rangelands?
  • What are the interactions and impacts of coyotes on white-tailed deer?

East Foundation is committed to using science to generate solutions to challenging problems. With this research, we are developing recommendations to reduce the risk of livestock and wildlife predation by coyotes.
