Unpublished Timber Rattlesnake account in The Natural History of Amphibians and Reptiles in Canada. Bulletin of the Antivenin Institute of America 3: 4357. Several varieties of snakes can be found in the area including the more common garter and milk snakes. 2. 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). Sex ratio in a New Jersey brood was 1:1 (Odum, 1979). 300 pp. They can live up to 25 years, reaching their adult size by about 45 years. 1953. The head is triangular with a distinct neck. 1980.

Reason for designationThe Timber Rattlesnake once occupied much of the Niagara Escarpment and other regions of southern Ontario, but has not been seen in the province since 1941 despite intensive searches and its easy identification. 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).

Female snakes usually do not eat during gestation. The cessation of feeding was apparently induced by the development of large offspring. In the northern part of their range, they hibernate from September to April (an average of 7.4 months) in communal dens. Copperhead. The rattle is the most obvious behavior of these snakes, apparently used when the individual feels angry or threatened. Jackson, S. and P. Mirick. Figure 1. Males are much longer and heavier than the females. It arose from the need for a single, official, scientifically sound, national listing of wildlife species at risk. COSEWIC status report on the Timber Rattlesnake Crotalus horridus in Canada, in COSEWIC assessment and status report on the Timber Rattlesnake Crotalus horridus in Canada.

Most people visiting the area see at least a few of these creatures during their tour. Favourite basking rocks are used year after year, and may attract many snakes at one time (Harwig, 1966). Doubleday, Page and Company. 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. 9. : extirpated 1993 Brown: probably extirpated [from Ontario]1999 Cook: almost certainly extirpated in Canada. 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).

The Timber Rattlesnake is a sit and wait predator. Harwig, S.H. From Oldham and Weller, 2000. In contrast, gravid females prefer less densely forested areas with 25% canopy closure, equal proportions of vegetation and leaf litter on the forest floor, frequent fallen logs and warmer climatic conditions (Ibid.).

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). Natural Heritage Information Centre, Ontario Ministry of Natural Resources (updated 15012001). Martof, B.S., W.M. The natural lifespan of the Timber Rattlesnake in the northern part of its range is approximately 25 years (Brown, 1993). Specific summer habitat requirements differ according to sex and age class. 1) The most common colour phases in the northern parts of its range are termed yellow and black, because the dorsal pattern consists of dark brown or black, V-shaped crossbands on a yellow, brown or black ground colour (Schmidt and Davis, 1941).

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.). Moler 1994. See Figure 1 for the North American range. Female Timber Rattlesnakes may or may not return to hibernation sites to give birth to young (Galligan and Dunson, 1979; DeGraaf and Rudis, 1983).

From I-190 S, take Exit 22. Dundee, H.A. In a Timber Rattlesnake population in New York, male roadkills outnumbered female roadkills 3.9:1.0, and humancaused mortality rates in general were much higher for males than for females (13:1) (Aldridge and Brown, 1995). The Niagara region has one of the largest inhabitations of reptiles and amphibians in the country. They are very loyal to their den site and will return year after year. Police received multiple calls about an adult woman and a child in the gorge near the Cave of the Winds Pavilion on the afternoon in question and responded at around 12:30 p.m., Rola said. COSEWIC status reports are working documents used in assigning the status of wildlife species suspected of being at risk. 1105 pp. An area of approximately 50 km of suitable habitat is required to sustain a population (Brown, 1993). Hike Description . Keenlyne, K.D. 1115 In Manual of Vertebrates of Ontario. 2001. COSEWIC Status Report on the Timber Rattlesnake Crotalus horridus in Canada 2001. Rattlesnakes are deaf to the sound of their own rattles, and are thought to use them when angry or threatened (Ditmars, 1907). Protected public lands and privately owned nature preserves have contributed significantly to the conservation of Timber Rattlesnakes where they still exist (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). Fatal bites often involve small children (Guidry, 1953), who are more sensitive to venom due to their smaller size. Putnams Sons, New York. Timber Rattlesnakes in the Big Black Mountain area of Kentucky play a prominent part in certain religious rites in the area (Barbour, 1950). 1908. . In Kentucky, we have four venomous snakes: the timber rattlesnake, pygmy rattlesnake (mainly found . Recently milked rattlesnakes are also capable of producing serious bites, and there is no evidence that previously exposed victims develop any sort of immunity through antibody production (Parrish and Thompson, 1958). Journal of Herpetology 2: 107-112. 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).

Reinert, H.K., D. Cundall and L. Bushar. Several biological traits of the Timber Rattlesnake greatly reduce its ability to recover from largescale losses of adults in a population. These demographic characteristics also make the Timber Rattlesnake a species in which there is little natural harvestable surplus of adult individuals (Brown, 1993). 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. Logier, E.B.S. The snakes mate in late summer, with the birth of 513 snakelings occurring from late August to mid September. As with most other reptiles, roadkill is an additional aspect of humaninduced mortality (Martin et al., 1992; Dundee, 1994b; Jensen et al., 1994).
