The sole purpose of Wildlife Services predator control is to prevent losses of commercial livestock due to predation by wolves, coyotes, mountain lions and other wild carnivores (NRDC, 2011). They work with state and local governments and use a combination of lethal control methods such as trapping, poisoning and firearms. There are many different types of entrapment, poisoning, and firearms. There are four main apparatuses used for trapping. Leg traps are designed to capture the animal by the toes, foot or leg, with a firm-grip metal trap. The animal captured by this method suffers many injuries, exposure, hunger and thirst. Conibear traps are a little more humane in the sense that they are designed to be a “quick kill” mechanism that crushes the animal to kill it. This type of trap is mainly used on aquatic animals, but captured pets have been found and some still alive. Cage traps are a fairly common use in urban areas. The animal is lured into the cage with some sort of club and remains unharmed (for the time being), most animals are killed and not released. Wildlife Services uses this method due to potential liability issues (NRDC, 2011). Wildlife Services also uses the killing technique. The first technique is aerial shooting, in which predators are shot down using helicopters or fixed-wing aircraft (NRDC, 2011). Shooting is a method they use by calling an animal and then shooting it. That means they use a call that sounds like prey, and when that animal approaches in search of food, Wildlife Services shoots it. Hunting dogs are used to track predators or as "bait dogs" to attract predators. The compound 1080 is a tasteless, odorless, colored...... middle of paper......and above all to the ecosystem with the killing of those animals and above all the poisons they use can completely destroy an ecosystem and do a lot more harm than good. Wildlife Services predator control uses many methods, some of which are under review for change. Petitions were filed and numerous letters were sent to the government and the company. Actions are being taken to reform this service for the better of ecosystems, livestock, predators and humans.
