• Evaluation of Wire Fences for Coyote Control

      Thompson, B. C. (Society for Range Management, 1979-11-01)
      Thirty-four electric and nonelectric wire fence configurations were evaluated for deterrent effect to coyotes (Canis latrans). Tests of fences were conducted using a conditioned test regime or live prey to elicit fence-crossing responses from 15 captive coyotes during 980 exposures to fences. Fence height and mesh size were important factors in controlling jumping over and crawling through, respectively. Overhangs and aprons were necessary to preclude climbing over and crawling under fences. Electric fences generally were not effective deterrents under test conditions. Construction of a fence necessary to deter all methods of crossing is described. Subsequent field tests have verified the suitability of such a fence to control losses of sheep to coyotes.
