Trail Patrol is a program that's part of the State Parks & Rec dept. They do a short class (3 hours?) to discuss how/what to do. The classes are infrequent, but if a big group is organized they will hold a special training for the group. We've got a lot of informal trail patrol groups and I've found them to be completely worthless. Trail Patrol should be the focus of an excursion, not a byproduct. If there were 20-30 people in the RME Trail Patrol Unit, it only takes a few people dedicated on a Saturday to make a difference. Rotate them around to cover an area each weekend. With 30 members in the Unit, three-person teams could be organized where each person only has to do 2 patrols each season and we'd have every weekend covered. Or the Unit could rotate between AF and the Snakes or something.
I don't think being Trail Patrol certified is necessary to accomplish the objective. The SP&R has their program, but UFWDA has a program as well that is quite similar. The training is just about how to approach people and for what reason and how to collect the right information to forward it to the right authorities.
Peer enforcement is a huge potential tool for closing the "management gap" that is a contributing factor to closure. I have yet to see an extremely effective peer enforcement group because most groups are very informal about it as I noted. I'm sure there are some active Trail Patrol groups in the state but I am not aware of them.
As usual, such an undertaking requires a leader to step up, make it happen, and keep it going.
