In the area where we hunt deer, coyotes are everywhere now. Use to be none in the area, and about 15-20 years ago they introduced them and wild turkeys. The turkeys are everywhere and eat the same stuff the deer like, and the coyotes chase/kill the deer. Last deer season we saw turkeys and yotes every day, and one single doe in the 2 weeks. Not sure how to get the deer back, but removing the yotes seems like a good start...
