There are a lot of foods that deer and hogs eat that are a shared food supply. BUT, for the most part, their feeding habits are very different. It is NOT the direct competition that most think it is!
Also, I wonder where all these deer that 'leave' these areas when hogs move in are going???? And, how do they decide where the boundaries are??
My lease has both.....and in higher numbers than you see in most areas. Neither are over-populated, and I have to work to keep the hog numbers in check. BUT, there is absolutely no doubt that not only can they co-exist, they can prosper and do well.
