The remote areas preferred by Timber Rattlesnakes are becoming increasingly less ideal because of enhanced access to such areas via fourwheeldrive and offroad vehicles (Galligan and Dunson, 1979; Brown, 1993).

Because the larger snakes somewhat resemble rattlesnakes and they tend to do a lot of basking in the sun, they can scare people. Timber Rattlesnakes are large, oviviviparous, iteroparous, longlived and slow to mature, with a relatively long mean generation time (Brown, 1991). Typical litter size varies from five to thirteen young, according to geographic location (Edgren, 1948; Anderson, 1965; Galligan and Dunson, 1979; Brown, 1993) and gestation period can vary as much as four to six weeks, depending on weather (Martin, 1996). Timber Rattlesnakes prefer areas not frequented by people (Ditmars, 1907; Anderson, 1965), although few such sites still exist (DeGraaf and Rudis, 1983). xxx + 450 pp. Variation in venom samples from copperheads (Agkistrodon contortrix) and Timber Rattlesnakes (Crotalus horridus). Experimental use of remotelytriggered cameras to monitor occurrence of Timber Rattlesnakes (Crotalus horridus). During courtship, the male repeatedly strokes the neck region of the female with his chin (Anderson, 1965). In summer, the preferred habitat for males and nonpregnant females is a wellcanopied forest with thick vegetation, whereas pregnant females prefer a more open forest with many fallen logs and a warmer climate. Venom is clear and watery in newborns, becoming bright yellow and concentrated as the snake matures (Johnson et al., 1968). Assessment based on a new status report. The introduction of pigs into the countryside contributed to the demise of the Timber Rattlesnake; pigs are protected from envenomation by their thick layer of fat that prevents the venom from entering circulation, and thus are able to kill and eat rattlesnakes (Nash, 1908).
