Al, if you and Mike are reading this, I applaud you for wanting to do something to protect sensitive areas.
Your only mistake is in putting all the information on the web, including photos. As you probably realize by now, you have incited too many people. There is nothing wrong with documenting problem areas by showing aftermath photos to the DEP, but then let the authorities take over. That is their job. Don't try to be a hero by turning people in. That will eventually end badly. Already this is probably causing yourselves needless anxiety.
I see an exponential increase in off-road activity. Yesterday I saw a place with highly endangered plants in the Pine Plains destroyed by an ATV. I can easily guess how this happened, because I personally witnessed just such a scenario a few years ago. A few truckloads of off-road vehicles pull up to the edge of Warren Grove, and offload. After buzzing around the sand roads for a few hours, they stop at a nice spot, usually near water, to eat and shoot the bull. Invariably, the free spirit of the group starts up his ATV and starts doing donuts in the mud at the edge of the water. In this case I saw yesterday, he then proceeded to go up the stream, knocking the living hell out of anything growing in his path. That rogue type of scoundrel is the type of person that authorities need to stop. I can even imagine others in the group looking on in disbelief at the offender. Maybe they'd say something, but the peer pressure is likely intense.
Just as is happening with the illegal dumpers, let the authorities handle it.
