Nobody "re-stocked" the coyotes. They slowly moved east over the last couple hundred years and filled a much needed missing niche in nature. We have a huge farm and the coyotes can been seen at any time of day eating woodchucks, rabbits, deer, voles, rats and other more destructive vermin. We have a huge deer population here which almost decimates our corn crop each year. If it weren't for the coyotes, we would have so many voles eating our strawberries. In fact, hunters are only allowed on our property if they obey our "do not shoot they coyotes" rule. The coyote has been around since the ice age and is here to stay, so you better get used to it. We irradicated wolves and coyotes on the east coast simply because we did not have the means to protect our livestock in any other way. Now we have ways to protect them. We have electric fences around all our crops, but some deer still get in. We don't shoot all the deer, we just try our best every year to keep them out. The eastern form of the coyote is doing two very important jobs right now, that of the wolves, and that of the coyotes. We would be overrun with deer and rodents, disease like lyme disease would flourish. So we have kinda like a coyote preserve here!
