I dont think that video really reveals that much that could threaten the snakes mentioned. For people who seek pine snakes the structure of the dens and were the eggs are laid is fairly well known. My only beef with the video is that a person will now know those three species exist on the grounds but that too is common knowledge to most.
Bob summed explained the situation well. It has always been a case of people employed or taking a very scientific approach to the barrens versus people who use it more for recreation. Those two will never see eye to eye completey, but there is a balance that truely needs to be found. I think the more you get to know the ecosystem the less you want to see people even out in the barrens. Everyone seems like someone who might impact the area negatively, be it poaching, orv use, etc. One thing with Emile though is he is very willing to get volunteers involved if they have that protective mentality over the barrens that alot of us share. If you show a real love of the barrens he will give you the time of day to discuss whatever you want and he is a great resource to get things accomplished. Its just those type that think the barrens is a playland to abuse that irratates him and he is vocal about that. Thats just my opinion from being in the field with him alot. He is actually great to be in the field with because he will bust balls all day and i dont think he truely is as big an elistist as maybe that video portrays, he just has a big big personality.
