Modern snares have what is called deer stops and this allows a deer to break free of the snare unharmed, so the whole argument is a joke. This is a very sore subject with me. This is totally ridiculous. If the so-called experts would get off their butts and do some research they would find that trapping is the most important tool used today to control predators. With trapping, the predator numbers stay at the carrying capacity of the land and more game animals flourish, including deer.
Coyotes are easier to snare than trap, in the deep winter snow.
Another study done out west found that a single coyote kills and eats 100 rabbits a year. You do the math. The Delta duck study hired a trapper to protect the nesting ducks in North Dakota. I ll get off the soapbox now and back to snaring. Snares come in different sizes and lengths.
