The land owners I worked for looked at it like a competeion for resourse . Hogs tear up feilds and knock over protein feeders. So the hogs are basicly getting the BEST resources the land managers are trying to feed the deer. Hogs multiply faster than deer their 4 they can take a place over quicker. My take is hogs can quickly over whelm a property if not trapped, hunted, OR hog-dogged.
