In Reply to: Neruotoxic properties found in Crotalus horridus horridus... posted by Jeremy G on November 18, 2002 at 08:43:58:

Jeremy:

If you can,try to get your hands on the following references:

"The timber rattlesnake: its distribution and natural history", pp. 13-22 IN: T. F. Tyning (ed.), Conservation of the Timber Rattlesnake in the Northeast. Massachusetts Audubon Society, Lincoln, MA (1992).

Brown, Christopher W. and Carl H. Ernst. 1986. A study of variation in eastern timber rattlesnakes, Crotalus horridus. Brimleyana 12:57-74.

The former defines "easter timbers", "canebrakes, and "western
timbers" (subspecies to some), the latter deals with simmilar issues, especially in North Carolina.

I feel that to some degree the limitation of horridus to steep, rocky areas in places like OK, KY, IN, OH, NC, is because these were the places which were not converted into farmland. If you go back in time 100 years, much more marginal land was farmed. Of course as you go north the need for exposed rock outcroppings becomes greater.

I lived near Durham in NC for five years, I always thought it was kind of funny how there were very few timbers in the Piedmont "intergrade zone" between the Appalachians and the coastal plains. There are some pockets though, although I never saw a Piedmont horridus myself. I wonder if there are historical records of more widespread occurance in the Piedmont, e.g. 200+ years ago?

More questions than answers, Carl B.
