Here in S.E. Michigan north of Detroit, it's heavily populated and these small wooded areas all harbor deer and the only thing controlling their populations are automobiles.
And another thing, I grew up in northern Michigan in the 50's thru the 60's and I never saw a turkey in my life. Now they're everywhere down here and you see them in the darndest places.
Turkeys have made a resurgence all over the country. Here in NC, the Forest Service and state parks actively manage habitat to benefit turkeys, quail, and other game birds. I’m sure it’s the same in other states.
You don’t have coyotes to help cars kill the deer?
My parents were born and raised in a tiny village on the Little Manistee River. I spent most every weekend and Summer living there.
I never saw turkeys when I was a kid but now there are several large flocks living all around the area.
Also, I saw only one bear in the Lower Peninsula through the time I graduated high school and went into the Air Force. Now black bear will come out of the woods and walk through the back yard of our yard. When I go out to cut fire wood I now carry a 10mm carbine and a 10mm pistol.
