Install electric fencing to reduce predation of livestock by mammals to reduce human-wildlife conflict
A replicated, before-and-after study in 1974–1978 on five farms in an area of boreal mixedwood forest of Alberta, Canada (Dorrance & Bourne 1980) found that installing electric fences reduced the numbers of sheep killed by coyotes Canis latrans. These results were not tested for statistical significance. During the three years after electric fences were installed at five farms, fewer sheep were killed by coyotes (26) than during the three years before the electric fences were installed (147). The study was conducted in five farms, each covering 6–65 ha. An annual average of 44–550 sheep grazed at each farm in May–October. Between 0.8 and 3.2 km of electric fences were installed at each farm in 1976–1977. At two farms, fences had one or two strands of barbed wire spaced 15 cm apart above 81-cm-high woven wire, with a charged wire placed 15 cm above the ground and another 12 cm from the fence around the outside perimeter. At three farms, the fence was made of seven 2.7-mm wires alternating charged and grounded. Predation losses were reported by farmers.
