Ask Dr. Dave: Does Culling Coyotes Work?

Ask Dr. Dave Samuel About Whitetails

Andy M. from North Carolina writes to ask about culling coyotes. “We’ve got a major coyote problem in my state and other Eastern and Southeastern states. Why do many biologists resist the idea to cull coyotes? Seems to me, getting rid of coyotes would help the deer.”

That’s a great question and one I hear from deer hunters all the time. The question is does culling coyotes change the coyote population over the long haul? Based on several studies I can say it does not. For example, a Deer Blog I receive in my e-mails, summarizes work done in South Carolina where coyotes are having a major impact on fawn recruitment. In that work, researchers removed an average of 4.2 coyotes per square mile per year from January thru April for three years. They removed 474 coyotes during that time on 37 square miles. In other words, they really hammered the coyotes. While doing that they followed 216 radio collared newborn fawns. Before coyote removal fawn survival was 23 percent. After two years of coyote removal, fawn survival was 20 percent. It did jump up to 43 percent after year three, but even so the cost to remove the coyotes was $123 per coyote and landowners or hunters just can’t afford to do that.

The Deer Blog also cited a culling study done on red foxes. That study was done on five areas in France and each area was 100 square miles in size. Hunters and trappers were recruited to help and they killed 3.8 foxes per square mile each year. That is a ton of dead critters! Carrying capacity for the foxes was estimated at 4 foxes per square mile. Even after killing 3.8 foxes per sq. mile, they could not lower late winter densities more than 25- to 32 percent and the reason was immigration. There was some impact if removal was done in the winter, but just as in the S.C. coyote removal study, it was hard to justify the expense for such a small gain.

Andy, one thing is for sure. We’ve got more coyotes than we’ve ever had, and there is a lot we do not know. But right now doing massive coyote removals just doesn’t seem economically feasible, and even if it was economically feasible, the gain in deer numbers isn’t much.

    Why are they figuring costs for culling by researchers? Just open a year round season with no bag limit and let hunters shoot them on sight for recreation. The culling produced results favorable to deer survival. It should not be stopped because of costs that are not needed in the first place.

    This is a prime example of why academia should not get invovled in the outdoors. It costs to much to do? Bullets are cheap and sportsmen are passionate about deer hunting. Killing the coyotes is the only option, if we don’t do that fawn recruitment is certainly going to go down.

    More coyote= more time to hunt them. Cost becomes irrelevant if it’s fun! If coyote are a problem on private property; invite a hunter in.

    Culling does not make a difference? Well, Where I grew up there were no coyote. They had been eliminated in this area. Now they are common. Logic dictates that dead coyote do not eat deer. So it may make some difference.
    This reminds me of a story about a boy who was found killing mice in the barn, The old man said to the young boy, there are so many mice out here you can’t possibly make a difference. The boy stomped another mouse running by and said, “I made a difference to that one.”

    Shop changed hands now BUT
    For the past several years a local sporting goods shop
    ran a largest coyote killed $1,000.00 prize per year
    and the shop had many hunters stopping BUY.
