For starters, I fail to see how the state could press charges without a landowner complaint. With no complaint, it's a victimless crime. Look at how hard it is to prosecute DV assaults where the victim decides he/she doesn't want to press charges. It CAN be done, but it is exceedingly difficult. I fail to see why a state would have ANY interest in prosecuting trespass cases absent a complaint from a landowner. The only way I could see this being beneficial to the state is if they are in an access contract with the landowner and can legally act as a representative of the landowner (no permission slip = a ticket).
As an aside, I am in firm support of strong trespass laws. However, I fail to see how reducing the level of notice to the public is a good thing, and seriously doubt it will help alleviate issues such as described by RoknHS. I would much rather see penalty escalators put in place that could go into affect IF certain posting requirements were met, to include painting a tree or a fence post orange.
Also, I question how much value there is in the felony clause. I don't have anything other than anecdotal data, but has a felony DUI clause ever stopped a guy from repeatedly getting behind the wheel of a car?
I firmly believe the best way to reduce trespass is engage the hunting community. I personally know of one ranch in Montana that battled a chronic trespass issue. Their approach was:
1) Very visibly posts all boundaries, including parcels of state land
2) Help, not hinder those who are legally hunting on state land
3) Allow a limited amount of free public hunting
4) Enroll several small, but high value portions of the ranch into Block Management
While this has not eliminated their trespass issues (nothing ever will completely do so), they have greatly diminished because other hunters who are using either the BMA, state land, or main portions of the ranch have a vested interest in preventing trespass. Think neighborhood watch group. If their is acrimonious tension between the landowner and the public, WTF is going to help them by calling in trespassers? I'm not.
