DeGraaf and W.R. Danielson. Additionally, the population genetics of Timber Rattlesnakes have been analyzed using microsatellite markers (Bricker et al., 1996; Villarreal et al., 1996; Bushar et al., 1998). Timber Rattlesnakes in the Big Black Mountain area of Kentucky play a prominent part in certain religious rites in the area (Barbour, 1950). Clearing of land, killing by humans and commercial exploitation have all contributed to the decline of the Timber Rattlesnake throughout its range (Weller, 1982; DeGraaf and Rudis, 1983). Keenlyne (1972) studied the sexual differences of feeding habits of Timber Rattlesnakes in Wisconsin. and F.M. Average shedding rate of Timber Rattlesnakes in northern New York was 1.44 sheds per year (Brown, 1988), compared to two sheds per year in Kansas (Fitch, 1985). Today, road accidents and human destruction of habitat (either directly or indirectly), and deliberate killing of venomous snakes all contribute to the Timber Rattlesnakes population reduction. Sutherland, I.D.W. The Ontario Ministry of Natural Resources Committee on the Status of Species at Risk in Ontario (COSSARO) has designated the Timber Rattlesnake an endangered species under the following criteria: any native species that, on the basis of the best available scientific evidence, is at risk of extinction or extirpation throughout all or a significant proportion of its Ontario range if the limiting factors are not reversed (Ibid.). Continuous disturbance of this sort may eventually cause snakes to abandon these sites altogether (Ibid.). Purification of high quality DNA from shed skin. Most snakes in Wyoming you'll find, though, are non-venomous - there are about 15 other types of Wyoming serpents out there!

Spend a few hours out on the rocks testing your strength. In 1971, Vermont became the last New England state to remove the bounty on the Timber Rattlesnake (DeGraaf and Rudis, 1983). Ovulation occurs from late May to early June, while maximum spermatogenesis is reached in July, continuing through September (Aldridge and Brown, 1995; Martin, 1993).

Protected public lands and privately owned nature preserves have contributed significantly to the conservation of Timber Rattlesnakes where they still exist (Ibid. 1996. Optimal forest composition and management strategies for Timber Rattlesnake habitat remain a subject of debate because canopy cover is a significant factor in the temperature profile of a den site. Similarly in Virginia, the three leading foods were mice, chipmunks and cottontail rabbits (Uhler et al., 1939).
