Timber rattlesnake populations:

Virginia Wildlife Action Plan Rating Tier IV - Moderate Conservation Need - The species may be rare in parts of its range, particularly on the periphery. Populations of these species have demonstrated a significant declining trend or one is suspected which, if continued, is likely to qualify this species for a higher tier in the foreseeable future. Long-term planning is necessary to stabilize or increase populations.


Southeastern "Canebrake" populations:

Males will often defend their mate from other males, but we have never seen it to this extreme. This 5ft. male is literally curled-up and sitting on the female. You can barely see the edge of the 4ft. female under him.
