I've spent many hours roaming the Bog. I also participated in a convervational search/survey for Massasauga's sponsered by Niagara College. We'd go out every weekend and find nothing, it was a good time, though in retrospect I think it was more destructive than helpful. I understand that later tha summer they did find one Massasauga and implanted a radio transmitter for tracking. At the time the water table was low as well (the year after the last fire).
I have found more Smooth Green snakes out there than I have anywhere else. Actually, that is the only place that I have found them recently
Have a good time and tread lightly!
