Well, I haven't read any of the biologist's reports, but I know that for about 30years prior to the coyotes moving in we would average around 100 ground hogs killed per year on our farm and the surrounding properties - probably about 250 acres mostly fields with plenty of little wood lots. The next year all the same holes had hogs in them.
This continued until the coyotes moved into the area....now if we see 5 woodchucks on the farm the entire year it's impressive. I'm not saying that other factors didn't contribute - just about every other game animal in PA has experienced some sort of plague. Maybe they all moved to Canada to flee the Trump Presidency....again!
Coyotes moving in also coincided with a decline in deer, rabbits, turkeys, barn cats, red fox, grey fox, hold over pheasants, and grouse. I'm sure that wasn't all the fault of the coyotes. But I still miss the smell of freshly baled hay stubble and gun powder on a warm July evening.
Bottom line.....maybe you'd be better off planning a trip out west to shoot prairie dogs.
Good Luck.
