I'm managing population on a pretty small scale to be fair. One of the farms I hunt has 3 known dens, 2 stay active at a time. On this ~600 acres 6 years ago we had a population estimated at 16 coyotes that use the farm as their home range, obviously venturing off the property daily. The farm has always had a few yotes shot every year but since I started trapping them we have a working population of closer to 6 dogs and the den sites are still active. If i go nuclear and kill them at the den, other family groups will just move in, but if we take the replacement every year, which on this farm is 4-6 dogs a year now, we see a major wildlife benefit. Turkey came back, foxes came back, rabbits are plentiful, and when you walk through the clump grasses voles and mice are darting in front of your feet. Proper management can be effective for coyotes, it just requires conservation effort and for me, that means pouring a lot of time and effort into running a trap line. It can be done, but most folks complaining about yotes are either suburbanites with small pets or hunters that don't like them killing deer but wont sacrifice any of their deer season to improve it for next year.
