Regrettably, dispersal methods are not effective in all situations, so other methods, including trapping or snaring, may have to be used. As bear and lion habitat continue to decrease, interactions between these animals and humans continue to increase. Bears are noted for destroying cornfields and trees, scavenging in garbage cans, demolishing the interiors of cabins and campers, and killing livestock. Lions are serious predators of sheep, goats, domestic pets, large livestock, poultry, bighorn sheep, and deer. Typical bear and lion predation on sheep leaves 10 or more killed in a single attack, and both species are known to attack humans.
Prevention is the best method of controlling bear and lion damage.
Heavy woven and electric fencing can effectively deter bears and lions from attacking livestock and damaging property. Loud music, barking dogs, exploder cannons, fireworks, gunfire, nightlights, scarecrows, and changes in the position of objects in the depredation area often provide temporary relief. The best way to protect pets is to keep them inside an enclosed kennel or shelter. Using guarding dogs, removing garbage and dead carcasses, and placing crops and beehives at considerable distances away from timber and brush may reduce damage by bears. Professional relocation of damaging mountain lions and bears is sometimes necessary.
