Interesting article but they forgot to add the blackfooted ferret.
Kind of hard to control the population when you don't let people posion or shoot them.
Depends on what size of bear you are looking for. If you are looking to get a big one go to a spot were he feel safe coming to and from your bait. So i guess cover is a big thing. You can get bears to come in any were but the bigger bears will probably won't came in till dark.
