Out here, you can be cited for both trespassing and poaching if you have crossed private land to get to a landlocked piece of BLM land to hunt. I know, because we used to call F&G wardens out on people for doing just that. The local judge was also a landowner, and he would throw the book at people - a $1500 fine, loss of the vehicle and firearms, loss of hunting rights for a few years, etc. The biggest landowner in the area is the Hearst Corporation, and they are big political contributors.
