Final edit by Ronald J. Brooks and Elinor J. Hughes. It is almost a certainty that the Timber Rattlesnake has been extirpated, as demonstrated by the following quotes: 1881 Garnier: rapidly becoming extinct [in Ontario] 1908 Nash: formerly common and generally distributed throughout the province now nearly extinct 1939 Logier: that the early distribution of this snake in Ontario was more extensive seems likely 1982 Weller: may very well have been extirpated in Ontario 1984 Cook: the last specimen taken in Ontario was from Niagara Glen in 1941 1989 Johnson: extirpated from Ontario 1989 Plourde et al. A number of populations from New York appear to have been extirpated, primarily because of overhunting (Brown, 1981). Timber Rattlesnakes generally begin to rattle when approached within 12 m (Barbour, 1950). 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. ): 198. Most rattle growth occurs within the first four sheddings, and the increase in diameter of successive segments is less than 5% after the seventh ecdysis (Fitch, 1985). The snake uses the rattle to warn potential aggressors to back off or to distract prey. The Timber Rattlesnake is a large venomous rattlesnake, characterized by yellow or brown coloring with dark brown or black Vshaped bands across the back. The locality was near an Indian village called Otinaoustettaoua, which is near presentday Waterdown, in Halton County (Ibid.). According to some researchers, the natural progression of forest succession may in fact be incompatible with the longterm survival of Timber Rattlesnake dens if the forest cover results in too much shade (Brown, 1993). Familiar amphibians and reptiles of Ontario. Trapido, H. 1939. Rattlesnakes documented in Grand Canyon National Park The larger division, adjoining the left, or Canadian, bank, is Horseshoe Falls; its height is 188 feet (57 metres), and the length of its curving crest line is about 2,200 feet (670 metres). In general, they do not strike unless provoked, preferring instead to remain concealed (Ditmars, 1907).

Reproduction of the Timber Rattlesnake (Crotalus horridus) in the Appalachian Mountains. Timber Rattlesnakes collected during organized roundups are often released far away from their point of capture, and this action most likely leads to the death of the snake, because of its unfamiliarity with its surroundings (Brown, 1993). A 5-year-old boy was rescued and his mother died after the two jumped 90 feet into the Niagara Gorge at Niagara Falls State Park on Monday, officials said. 1981. Crotalus horridus (Timber Rattlesnake) coloration. The only Canadian report of a possible Timber Rattlesnake bite, and subsequent fatality, was that of a soldier bitten during the Battle of Lundys Lane near Niagara Falls in 1814 (see Cook, 1999 for details). Niagara is far from the highest waterfall in the world, or even in New York. Although these snakes are not normally aggressive, they can bite if surprised or threatened. Many translocated snakes immediately leave the area in which they are released (Galligan and Dunson, 1979). The last Timber Rattlesnake sighting was in the Niagara Gorge, Ontario in 1941 (Ontario Herpetofaunal Summary [OHS], unpubl. The rattle is found at the tip of the rattlesnake's tail. 1948. Historically, they have been subject to human exploitation, such as bounty hunting, collection and sport hunting. This species occurs throughout the eastern and central United States, although it is locally extirpated in many areas. Brown, W.S., L. Jones and R. Stechert.

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 snake feeds on rodents and other small mammals. It arose from the need for a single, official, scientifically sound, national listing of wildlife species at risk. Over the years it has become a thriving ecosystem home to birds, fish, turtles, snakes and more! 1968. 1960. In the nineteenth century, hunting parties would attack den sites and kill all the snakes that could be found. It can grow to almost two metres long. Most people visiting the area see at least a few of these creatures during their tour. Human exploitation, through bounty hunting, commercial collecting and sport hunting, is the leading cause of Timber Rattlesnake decline throughout the species range (Galligan and Dunson, 1979; Brown, 1993). Reinert and L. Gelbert. DeGraaf, R.M. All available evidence indicates that the population size of the Timber Rattlesnake in Canada is zero.

In Ontario, the Natural Heritage Information Center determined that the Timber Rattlesnake is extirpated, the chance of rediscovery being very small. Distribution of the Timber Rattlesnake (. Saenz, D., S.J. The ideal habitats for this rattlesnake are forested areas with rocky outcrops, dry ridges and second growth coniferous or deciduous forest. 1982. Harold McNeil. Lutterschmidt, W.I. Small mammals are the favoured prey; different species are consumed in proportion to their prevalence at the site. Low 37F. The combat dance of male Timber Rattlesnakes has been interpreted either as an expression of sexuality, or as a competitive interaction for food or dominance (Sutherland, 1958). 1994a. Journal of Herpetology 16(2): 145150. Fat stores are extremely diminished in postpartum females (Gibbons, 1972), with a mean mass difference of 306 g between gravid and postpartum females in a New York population (Brown, 1991). Observations on gravid females in captivity also indicated that the snakes did not feed during gestation (Odum, 1979). COSEWIC MembershipCOSEWIC comprises representatives from each provincial and territorial government wildlife agency, four federal agencies (Canadian Wildlife Service, Parks Canada Agency, Department of Fisheries and Oceans, and the Federal Biosystematic Partnership), three nonjurisdictional members and the co-chairs of the species specialist groups.

Timber Rattlesnakes prefer areas not frequented by people (Ditmars, 1907; Anderson, 1965), although few such sites still exist (DeGraaf and Rudis, 1983). The Timber Rattlesnake is no longer found anywhere in Canada. Rupert, R. Jr. and H.K. Mean age of first reproduction for females averaged 7.8 years in northwestern Virginia (Martin, 1993), 6 years in South Carolina (Gibbons, 1972), four years in Kansas (Fitch, 1985) and 910 years in northeastern New York (Brown, 1991). The minimum viable population size for Timber Rattlesnake recovery is estimated at 30 to 40 individuals with an even age distribution and at least four or five mature females per den (Brown, 1993). University of Toronto Press, Toronto, Ontario. Of the populations that remain, many have been reduced to 1520% of their numbers a few decades ago (Martin, 1983). Striped mutations and amelanistic partial albinos have also been recorded (Hudson and Carl, 1985; Dundee, 1994a). The last sighting of one of these venomous . Look at the eyes.

Movements of gravid females are generally confined to thermally optimal gestation sites, such as open outcrop knolls in the vicinity of the den (Reinert and Zappalorti, 1988b; Brown, 1991). The Timber Rattlesnake was among the first snakes to be officially designated as an endangered species under Ontarios Endangered Species Act, 1973 (Weller, 1982). It stretches 11 kilometers (6.8 miles) north of Niagara Falls. COSEWIC. Timber Rattlesnakes in the Big Black Mountain area of Kentucky play a prominent part in certain religious rites in the area (Barbour, 1950). Protected public lands and privately owned nature preserves have contributed significantly to the conservation of Timber Rattlesnakes where they still exist (Ibid. 253 pp. The University of Michigan Press, Ann Arbor: MI. The rattle is the most obvious behavior of these snakes, apparently used when the individual feels angry or threatened. 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). Proceedings of the Ninth Annual Meeting of the Ohio Herpetological Society 5: 163. Bushar.

Assessment based on a new status report. Symptoms of Timber Rattlesnake poisoning include swelling, pain, respiratory difficulty, weakness, giddiness, haemorrhage, weak pulse or heart failure, nausea, vomiting, ecchymosis, heart pain, gastric disturbance, paralysis and unconsciousness or stupor (Hutchinson, 1929). Larson and T.H. Conversely, in a study in Georgia, gravid females constituted the majority of roadkilled snakes (Neill, 1948). The adult snakes are large, ranging from 887-1892 mm (34.92 - 74.49 inches) in total length (Collins and Knight 1980).

Hibernation in the northern parts of the Timber Rattlesnakes range occurs in the cracks of rocky ledges, usually facing south (Odum, 1979). 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. G.P. Logier, E.B.S. Kim has also written COSEWIC status reports on the queen snake (Regina septemvittata) and the northern ribbon snake (Thamnophis sauritus septentrionalis). 1996.

This is a shy and secretive species and reports of Timber Rattlesnakes biting humans are rare (Ditmars, 1907; Brown, 1981). In Ontario, hibernacula were most often located along the Niagara escarpment, following the limestone outcropping northward toward the Manitoulin District (Logier and Toner, 1961). The most distinctive behaviour of rattlesnakes in general is the use of the rattle itself. By Harold McNeil Buffalo News.
