SARA establishes COSEWIC as an advisory body ensuring that species will continue to be assessed under a rigorous and independent scientific process. 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. It is an endangered species in Massachusetts, where it may not be harassed, killed, collected or held in possession except under special permit (Jackson and Mirick, 1996). Copeia 1988(4): 964978.

The Niagara region has one of the largest inhabitations of reptiles and amphibians in the country. Brown, C.W. Male Timber Rattlesnakes may use scent trailing to locate receptive females (Reinert and Zappalorti, 1988b). 1982. 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). Relict populations of Timber Rattlesnakes were known to have persisted on South Bass Island and on the Catawba peninsula of Ohio until at least 1951 (Langlois, 1951). Observations on rattle size and demography of prairie rattlesnakes (Crotalus viridus) and Timber Rattlesnakes (Crotalus horridus) in Kansas. Hibernation in the northern parts of the Timber Rattlesnakes range occurs in the cracks of rocky ledges, usually facing south (Odum, 1979).

New York State Park Police report that the youth has undergone surgery. Migration distances of males in general are greater than those of females because they actively engage in seeking mates (Reinert and Zappalorti, 1988b). 1953. Monday, June 18, 2012 Snakes in the Niagara Gorge Who would have thought that the largest snake I ever saw in New York would be in the Niagara Gorge. Spend a few hours out on the rocks testing your strength. Timber Rattlesnakes are large, oviviviparous, iteroparous, longlived and slow to mature, with a relatively long mean generation time (Brown, 1991). Crotalus horridus (Timber Rattlesnake) reproductive phenology. Niagara Falls empties into Niagara Gorge, where the cliffs reach almost 1,200 feet above the Niagara River. Because of their late maturing and infrequent reproduction, this life history strategy makes them incredibly susceptible to human persecution and habitat destruction. During hibernation in the same population, mean body temperatures from September through May ranged from 4.3C to 15.7C, with a mean value of 10.5C (Brown, 1982). The Timber Rattlesnake is a large venomous rattlesnake, characterized by yellow or brown coloring with dark brown or black Vshaped bands across the back. This species occurs throughout the eastern and central United States, although it is locally extirpated in many areas. Conserving the Timber Rattlesnake. Johnson, B.D., J. Hoppe, R. Rogers and H.L. Brown, pers. 124 pp. 1996. 1994. and for their rattles (Anderson, 1965). In Missouri, the Timber Rattlesnake population is gradually being reduced, and the species has been practically exterminated in some areas where it was formerly common (Anderson, 1965). The Massasauga rattlesnake has nine large scales on its head, whereas the Timber Rattlesnake has many small scales on its head. Trapido, H. 1939. Smith, Kim. The Timber Rattlesnake has already been designated as extirpated in Ontario by the Nature Conservancy (Oldham, 1997), and the vast majority of experts agree that the Timber Rattlesnake no longer exists in Canada. Reinert, L. Gelbert and L.M. Because females do not mature until about eight years old and reproduce on average only once every three years (Martin, 1993), most females will give birth to no more than five broods throughout their lifetime, assuming a lifespan of 22 years (Brown, 1991). 2001. They have been extirpated from the states of Maine and Rhode Island, and may be close to extirpation in New Hampshire (Brown, 1993). The females reproduce once about every three years. Reproduction, growth, and sexual dimorphism in the canebrake rattlesnake (Crotalus horridus atricaudatus). The dynamics of this population suggests a rapid turnover, with newly matured adults comprising a high proportion of the total population. Rattlesnakes are where and when you find them. The Timber rattlesnake is a greyish-brown to yellow, thick-bodied snake with a triangular-shaped head and dark markings that start as blotches on the front of the body but are fused together to form crossbands (chevron-shaped markings) along most of the body and the tail. But, for the real treat, skip the bridge and head on. Journal of Herpetology 29(3): 399407. The rattle is the most obvious behavior of these snakes, apparently used when the individual feels angry or threatened. Harding, J.H. Eastern Massasauga Rattlesnake This is the smallest of the three venomous snakes in New York, with an average size of 1 to 3 feet in length. The site also contains some of the best-exposed fossils you'll find in the entire Niagara Region. Herpetologica 12: 326. Designations are made on all native species for the following taxonomic groups: mammals, birds, reptiles, amphibians, fish, lepidopterans, molluscs, vascular plants, lichens, and mosses. Taken together, these factors result in a small number of new individuals added to the population each year. Low 37F. Crotalus horridus (Timber Rattlesnake) coloration. 1983. An upstate police department is warning locals to "beware of rattlesnakes" after it received two separate calls over the weekend regarding sightings of venomous timber rattlers. 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. 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). Inconnus et Mconnus: Amphibiens et Reptiles de la province de Qubec. However, none of these reports has ever been fully substantiated, and the adjacent populations in New York State (which may have acted as a source population for Quebec) have been extirpated (see Cook, 1999 and Mlanon, 1950 for more detailed summaries of Quebec reports). Population declines have also been noted throughout the Timber Rattlesnakes range in the United States, particularly in New York, Pennsylvania, Virginia, Connecticut and New Jersey (Brown, 1981, 1993; Reinert, 1990). Putnams Sons, New York. The timber rattlesnake (Crotalus horridus) is the only wide-ranging woodland rattlesnake of deciduous forests in eastern North America (Smith 2001). When the calm meets the storm: the White Water Walk is the tourist trail following the Great Gorge. Brown, W.S. The snake is slow to mature, has few snakelings in each litter and a low juvenile survival rate. Translocated males have significantly larger activity ranges, range lengths and mean distances moved per day than native males (Rupert and Reinert, 1992). The path will go slightly uphill, but nothing that requires too much exertion. Timber Rattlesnakes prefer areas not frequented by people (Ditmars, 1907; Anderson, 1965), although few such sites still exist (DeGraaf and Rudis, 1983). 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). Trilobites . Mountain Lion . Opinion varies as to whether females give birth at den sites or at maternity rocks some distance away (Galligan and Dunson, 1979). Cave of the Winds "Express-Pass" Adventure USA Tour. Cover illustration/photo:Timber Rattlesnake -- Illustration by Marisa Bonofiglio, Woodbridge, Ontario. Several varieties of snakes can be found in the area including the more common garter and milk snakes. Anderson, P. 1965. Brown, W.S. Crotalus horridus (Timber Rattlesnake). 1980. There are many ways to contact the Government of Ontario. Continuous disturbance of this sort may eventually cause snakes to abandon these sites altogether (Ibid.). Contributions of the Royal Ontario Museum Life Sciences 53: 192. This rattlesnake was found along the Niagara Escarpment, primarily in the Niagara area. Historically, the snake ranged throughout southern Ontario and southern Quebec. The severity of a snakebite depends on the amount of venom injected, the toxicity of the venom, and the depth and location of the bite (Minton, 1953). These demographic characteristics also make the Timber Rattlesnake a species in which there is little natural harvestable surplus of adult individuals (Brown, 1993). Martof, B.S., W.M. The Journal of Heredity 87(2): 152155. and C.H. Rattlesnakes have the cat-like vertical pupils common to most venomous snakes unlike the round pupils of most non-poisonous snakes. The 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. It arose from the need for a single, official, scientifically sound, national listing of wildlife species at risk. Although some authors believe that colour phases are sex related (Ditmars, 1907), others have suggested that the variation is a thermoregulatory adaptation, as black specimens occur with greatest frequency in mountainous regions (Schaeffer, 1969). Emergency crews performed life . Fatal bites often involve small children (Guidry, 1953), who are more sensitive to venom due to their smaller size. Of the populations that remain, many have been reduced to 1520% of their numbers a few decades ago (Martin, 1983). Variations of these colour phases occur in the western and southern portions of its range (see canebrake rattlesnake, below) (Conant and Collins, 1991). 2000. Specific summer habitat requirements differ according to sex and age class. Timber Rattlesnakes can be confused with Massasauga rattlesnakes and some nonvenomous species, such as the fox snake. 85 pp. 1105 pp. However, the rush of over 6 million cubic feet of water per minute, approaching the cascade at about 25 miles per hour, and plunging 70 to 190 feet across a distance of about 3000 feet, make it one of the natural wonders of the world. Unpublished Timber Rattlesnake account in The Natural History of Amphibians and Reptiles in Canada. 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. Frank Darroch collected the last confirmed Timber Rattlesnake in the Niagara Gorge on August 22, 1941 (Cook, 1999). The caudal lure of various juvenile snakes. to Fitch, 1985). Notes on a litter of young Timber Rattlesnakes. Schaeffer, G.C. Batrachians and reptiles of Ontario. Shedding rate and rattle growth in Timber Rattlesnakes. comm.). Timber Rattlesnakes are one of only a handful of North American rattlesnakes that are found east of the Mississippi River (Schmidt and Davis, 1941; Morris, 1974). How to comment on protecting species at risk, How to get an Endangered Species Act permit or authorization. Males are much longer and heavier than the females. It stretches 11 kilometers (6.8 miles) north of Niagara Falls. Since 1996, the Nature Conservancy has ranked the Timber Rattlesnake G5 (Oldham, 1997). Rattlesnake Point Located conveniently near to Toronto is Rattlesnake Point, an excellent spot for rock climbing. Striped mutations and amelanistic partial albinos have also been recorded (Hudson and Carl, 1985; Dundee, 1994a). Nash, C.W. 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. Males grow considerably longer and heavier than females, and there is no apparent reproductive advantage for females obtaining a larger body size (Gibbons, 1972). Dundee, H.A. This is true for two reasons; first, a segment is added each time a snake sheds (not necessarily once a year) and second, segments are continually being broken off most wildcaught individuals have between five and nine segments in their rattles (Schmidt and Davis, 1941). In Pennsylvania, newborns ranged from 220280 mm snoutvent length (SVL) (Galligan and Dunson, 1979). Timber Rattlesnakes in the Big Black Mountain area of Kentucky play a prominent part in certain religious rites in the area (Barbour, 1950). Niagara is far from the highest waterfall in the world, or even in New York. Alfred A. Knopf, New York. The last state lifted the bounty on Timber Rattlesnakes in 1971. Rattlesnakes are deaf to the sound of their own rattles, and are thought to use them when angry or threatened (Ditmars, 1907). Herpetologica 6(3): 6670. Bites from rattlesnakes at the time of shedding and replacement of fangs indicate that the injection apparatus may not be fully functional at this time, as some victims bitten during this period did not exhibit any symptoms of poisoning (Hutchinson, 1929). The Timber Rattlesnake is no longer found anywhere in Canada. The varied patterns of flow across . Timber Rattlesnake in Massachusetts, web site http://www.umass.edu/ umext/snake/timber.html. Weller. Special Concern (SC)* A wildlife species that may become a threatened or an endangered species because of a combination of biological characteristics and identified threats. Although the taxonomic status of the Timber Rattlesnake remains somewhat ambiguous in the eastern portion of its range (Brown and Ernst, 1986), it is generally accepted that the subspecific status of the canebrake rattlesnake is not warranted (Behler and King, 1996) and that Timber Rattlesnakes are monotypic (Collins and Knight, 1980). L.K. Sex ratio in a New Jersey brood was 1:1 (Odum, 1979). Over a few decades, a single Timber Rattlesnake hunter is known to have collected 29005000 snakes from New York alone (Stechert, 1982; Brown et al., 1994). In Ontario, the Natural Heritage Information Center determined that the Timber Rattlesnake is extirpated, the chance of rediscovery being very small. i-iv + 178. Timber Rattlesnakes generally begin to rattle when approached within 12 m (Barbour, 1950). 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. A comparison of movement patterns: native vs. translocated Timber Rattlesnakes (Crotalus horridus). Clarke. Timber Rattlesnakes in South Carolina reached lengths of 650750 mm SVL by the end of their second summer (Gibbons, 1972). Martin, W.H.

Now go up the Genesee River and the probability of finding a rattlesnake goes up dramatically. 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). Though they are mostly active by day, during a hot summer they may also be active at night.
