In order to resolve wildlife conflicts and allow people and wildlife to coexist, 76,859 coyotes were killed in 2016. Neck snares and other traps are used in addition to shooting them from the ground, from planes and helicopters. In order to promote compassionate conservation, non-lethal coyote controls like electric fencing are used to prevent losses even before they occur.
Aside from shooting the coyotes with a gun, Wildlife Services uses armed sheep with collars containing liquid poison. M-44 bombs were distributed to inject sodium cyanide into the mouth of the animals that will feed on them.
In 2016, more than 40,000 coyotes were killed by Wildlife Services in Nevada. However, according to an article in Scientific America, there is no evidence that the use of lethal control reduces the population of the predators. In fact, lethal options seem to make the problem worse.
Shooting coyotes can be unproductive because even if they are killed year after year, their populations remain the same. In other areas, their numbers are increasing. In the Coyote Project website, you will understand that their mission is compassionate conservation and coexistence between humans and wildlife through education, science and advocacy.
According to reports of Coyote Project, livestock losses are certainly part of ranching. When the predators kill livestock, it results into coyotes bring killed. However, the killing is usually reactive because it happens after the livestock has been killed. There is no assurance that the actual coyote that caused the problem was killed.
Killing coyotes is time consuming and labour intensive. There are instances when non-target animals or livestock are killed in the process. Predator proof fencing is proactive but it is also expensive. Guardian dogs are also expensive and need a year of training. A cheaper option is electric fencing that is safe and effective to protect livestock from predators.
The most effective and least expensive option for animal control is electric fencing that works with energizers that converts power into brief high voltage pulse that will cause an uncomfortable electric shock. The type of energizer used on the electric fence depends on the remoteness of the location and the size of the area that has to be fenced.
