That looks like a raccoon stool sample. Coyote scat will have lots of fur, and some small bones. If you turkey hunt, you can help them out by trapping the raccoons as they are probably the number one turkey nest predator. I've had good luck with dog proof traps with cheap dry cat food.
As far as trespassers, me and my wife own 160 acres. Both 80's we bought were known as being good for hunting, and were not posted or patrolled by the former landowners. Be polite but firm when locals stop by and feel you out. Let them know that whatever went on there before is done. Too bad. Toss out words like prosecution, trail cameras, whatever to let them know you won't just ask them to leave every time they are caught. I try to make sure their spouse is around when I have the "howdy neighbor, please don't trespass" talk, no husband wants to explain a sheriff visit, court and attorney costs to his wife just because he got caught trespassing. Chances are she resents his hunting time anyway. They may live near you, but they have to live with her. You will never keep every cretin off your land, but you can deter the casual guys that try to "round off" their property. I've got 7- 10 acre properties that back up to my south 80. Looking at logging a 60' swath along that property line, and fencing it down the road if I have any problems.
Biggest turds seem to be the spring morel hunters, almost got a trail camera stolen this spring by one of them. I had the camera in a steel box, lag bolted to a big tree. The camera was on video mode, so I got a nice clip of him approaching the camera, and then the whole box rocking slightly, and some audio of an out of shape slob grunting and wheezing trying to pull it off.
Anyway, jealous of that PTO snowblower.
