If it oinks, shoot it. That's basically what Ohio wildlife officials are telling hunters who encounter wild boars in their state, according to this report from the Toledo Blade. The number of wild boars (Sus scrofa, also called feral pigs) in Ohio has reached a level where hunters would have to kill 80% of them just to keep populations stable (I can't seem to find out exactly what that number is - either there are a lot of them or they are very, very fertile!). The article notes that some of the blame for the continued spread of the wild boar belongs to hunting reserves, where the animals are known to occasionally escape into the wild. Ohio hunters are being asked to do their state a favor and "pig out" year round. As encouragement, the Ohio Department of Natural Resources has produced a color map (pdf) showing prime boar habitat throughout the state, and is asking successful hunters to post photos to this website (P.S. - those are hunting photos, so if you don't like seeing dead animals, skip the link!).
