Timber Rattlesnakes on the Lake Erie islands. The designation of status for the Timber Rattlesnake is quite straightforward: it has not been reported in this country in almost 60 years. By the early 1970s, the Timber Rattlesnake had been nearly extirpated in all but the most remote sections of the United States (Morris, 1974). 1956. 1991. Similarly in Virginia, the three leading foods were mice, chipmunks and cottontail rabbits (Uhler et al., 1939).

Committee on the Status of Endangered Wildlife in Canada. They tend to disperse upslope to high ridges removed from human settlement when they emerge from hibernation (Brown, 1981), and move in a looping pattern during the active season that returns them to the same hibernaculum (Reinert and Zappalorti, 1988b). 1996. and F.M. 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.). Journal of Herpetology 27(2): 133143. Garnier, J.H. Since this time, many researchers have conducted searches (including Frank Darroch, E.B.S. http://www.mpm.edu/collect/vertzo/herp/timber/htm.

However, in light of its rangewide decline, the U.S. Kim Smith completed her Honours B.Sc. Crotalus horridus (Timber Rattlesnake) climbing. The pit and the vertical nature of the pupil are characteristics that can be used to distinguish the Timber Rattlesnake from similarly patterned nonvenomous snakes, such as the eastern fox snake (Elaphe gloydi)(Harding, 1997). From easy to challenging trails - including steep stairways and a little boulder hopping, hiking is recommended between April and mid-November. While there are many different types of snakes found at New River Gorge National Park and Preserve, only two types are venemous; the Northern Copperhead and the Timber Rattlesnake. The Timber Rattlesnake is a heliothermic species, with the ability to regulate its temperature by radiation absorption throughout its daytime activities (Odum, 1979). Observations on gravid females in captivity also indicated that the snakes did not feed during gestation (Odum, 1979).

Kim has also written COSEWIC status reports on the queen snake (Regina septemvittata) and the northern ribbon snake (Thamnophis sauritus septentrionalis). A high-level whistleblower, who spoke on condition of anonymity, has revealed information that a den of Eastern Massasauga rattlesnakes, which are protected by law as a New York State endangered species, was observed in close proximity to the controversial construction site as recently as two years ago. Gravid females are particularly susceptible to persecution due to their preference for more open habitats and the predictability with which they occupy specific sites (Brown, 1993). Of a litter of twelve born to a New York snake, one was stillborn and an infertile egg was also deposited (Stewart et al., 1960). 1958. Brown, W.S. 9. Hibernation is almost always communal, with only scattered reports of individuals hibernating singly (Neill, 1948; Odum, 1979). Rattlesnakes encounters can be common when walking about in the eastern side of the Columbia River Gorge. Herpetological Review 26(4): 189190. I've heard that there have been reports of people seeing or hearing rattlesnakes at the G12 area, so I found this article about the snake and what to do. 1958. Venom is clear and watery in newborns, becoming bright yellow and concentrated as the snake matures (Johnson et al., 1968). Herpetological Review 27(3): 144145. 1939. Brown, pers. Other habitat components are the summer habitat, where snakes move and forage, and transient habitat located in between summer habitat and the den (Brown, 1993). To discriminate between timber and Massasauga rattlesnakes (Sistrurus catenatus), the number and size of the scales on the dorsal surface of the head can be informative. 1994a. Burgdorf, D.C.

Stewart, M.M., G.E. All nonvenomous snakes lack the facial pit of the rattlesnakes. In a letter to Francis Cook dated 15 September 1963, Frank Darroch described the changes to the habitat where he collected the last known Timber Rattlesnake in Ontario in 1941 (Cook, 1999): The place where I found the snake has in the last ten years been entirely destroyed as a habitat, by the new road put in for the new hydro power plant. Thus, the persistence of Timber Rattlesnakes in that area of the Niagara region seems highly unlikely. Department of Education, Toronto, Ontario. Another possibility was that it merely swam or drifted across Lake Erie from a neighbouring population on one of the U.S. islands or mainland (F. Cook, pers. There are near-constant views of the impressive Niagara River and powerful rapids below. 2. Timber Rattlesnakes in South Carolina reached lengths of 650750 mm SVL by the end of their second summer (Gibbons, 1972). 2.

Funding for this effort was provided by the 2010 US Environmental Protection Agency's Great Lakes Restoration Initiative. Ernst. 1989. comm. Reinert, H.K. Smith, Kim. 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). The timber rattlesnake (Crotalus horridus) is the only wide-ranging woodland rattlesnake of deciduous forests in eastern North America (Smith 2001). Langlois, T.H.

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. Copperhead. This ability could be crucial to the survival of newborns through their first winter, as they may be born a considerable distance away from any suitable hibernaculum (Reinert and Zappalorti, 1988a). Cedar City rancher Kerry Jensen crossed paths with a rattlesnake in Shurtz Canyon on Cedar Mountain which is around 7,000 feet in elevation.
