Penalties can range as high as a $5,000 fine and/or imprisonment for 180 days, in addition to a restitution payment of $2,000 per animal killed (Ibid.). Bounty records from one county in Minnesota declined from 4,955 in 1980 to 191 in 1987 (Ibid.). Harold McNeil. It's fairly rare to see a rattlesnake along the PCT in Oregon, but it does happen. Bushar, L.M., H.K. In Kentucky, we have four venomous snakes: the timber rattlesnake, pygmy rattlesnake (mainly found . 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). Kim Smith completed her Honours B.Sc. At the time of European settlement, the Timber Rattlesnake was found in 30 states and was extremely abundant in areas of suitable habitat (Casper and Hay, 2001). The head is triangular with a distinct neck. 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. In Galligan and Dunson, 1979 (above). In Wisconsin, bounty records showed a 7080% decline over a sevenyear period (Casper and Hay, 1998). 1115 In Manual of Vertebrates of Ontario. Crotalus horridus (Timber Rattlesnake) coloration. Herpetological Review 25(1): 28. Clarke. Niagara Falls empties into Niagara Gorge, where the cliffs reach almost 1,200 feet above the Niagara River. Anderson, P. 1965. According to Casper and Hay (2001), C. horridus is designated as extirpated in Maine and Rhode Island, endangered in Connecticut, Massachusetts, New Hampshire, New Jersey, Ohio, Vermont, and Virginia, threatened in Illinois, Indiana, Minnesota, New York, and Texas, a protected species in Maryland and Kansas, protected from take in Oklahoma and Pennsylvania and a protected wild animal in Wisconsin. Growth rate slows after maturity (Galligan and Dunson, 1979), and adult total length ranges from 9001890 mm (Conant and Collins, 1991). 1988b. and G.C. Because the larger snakes somewhat resemble rattlesnakes and they tend to do a lot of basking in the sun, they can scare people. Catalogue of American Amphibians and Reptiles 253.1253.2. One Utah rattlesnake population heavily hunted for only one year had still not recovered 12 years later (Woodbury and Hansen, 1950 cited in Galligan and Dunson, 1979). This species occurs throughout the eastern and central United States, although it is locally extirpated in many areas.

The Timber Rattlesnake has many small scales, whereas the Massasauga has nine large scales (Ibid.). The Timber Rattlesnake is a large venomous rattlesnake, characterized by yellow or brown coloring with dark brown or black Vshaped bands across the back. 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). Cameron, Toronto, Ontario. As such, they have the capacity to contribute significantly to our knowledge of covariation in life history traits (Ibid.). 9. Martin, W.H. From easy to challenging trails - including steep stairways and a little boulder hopping, hiking is recommended between April and mid-November. You will not receive a reply. It stretches 11 kilometers (6.8 miles) north of Niagara Falls. A case in herpetological conservation: notorious poacher convicted of illegal trafficking in Timber Rattlesnakes. 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). Final edit by Ronald J. Brooks and Elinor J. Hughes. Rattlesnakes have a thick, broad body and a distinctive diamond-shaped head, although this is also true of some of our non-venomous snakes. 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). Western Diamondback Rattlesnake. The Niagara Gorge is an 11-kilometer-long gorge that divides Canada and the United States, carved out by the great Niagara River thousands of years ago. Ontario Herpetofaunal Atlas. It is therefore assumed that the size of the Canadian population of Timber Rattlesnakes is zero. The colonial nature of Timber Rattlesnakes was a factor contributing to their extirpation from Canada by humans (Plourde et al., 1989). In Pennsylvania, newborns ranged from 220280 mm snoutvent length (SVL) (Galligan and Dunson, 1979). and C.H. Committee on the Status of Endangered Wildlife in Canada.

There are many ways to contact the Government of Ontario. 5. Niagara Falls, NY (14301) Today. The site also contains some of the best-exposed fossils you'll find in the entire Niagara Region. 1948. Death from a Timber Rattlesnake bite can occur in as little as 35 minutes (Hutchinson, 1929), particularly if the individual is allergic to pit viper venom (Parrish and Thompson, 1958). Species at Risk Act: COSEWIC assessments and status reports, History of the Timber Rattlesnake in Canada, Population Distribution, Persistence and Trends, Figure 1. ): 198. Favourite basking rocks are used year after year, and may attract many snakes at one time (Harwig, 1966). Timber Rattlesnakes are large, oviviviparous, iteroparous, longlived and slow to mature, with a relatively long mean generation time (Brown, 1991). If the rattle becomes accidentally lost, the end of the tail remains blunt, never pointed (Ibid.). Woodbury, A.M. and R.M.

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. In summer, the preferred habitat for males and nonpregnant females is a wellcanopied forest with thick vegetation, whereas pregnant females prefer a more open forest with many fallen logs and a warmer climate. Migration distances of males in general are greater than those of females because they actively engage in seeking mates (Reinert and Zappalorti, 1988b). Extirpated (XT) A wildlife species no longer existing in the wild in Canada, but occurring elsewhere. Timber Rattlesnakes are seasonally migratory, from den to summer range and back (Brown, 1993).

Notes on a litter of young Timber Rattlesnakes. Duran. 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). 1957. . Male snakes mature at a mean age of 4 years, while females mature at a mean age of 6 years, depending on the location of the population. 2. Conserving the Timber Rattlesnake. Jackson, S. and P. Mirick. 1985. 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). 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). Due to their appearance and frightening actions, people assume snakes to be dangerous (Edward & Foote, 1979). Niagara Gorge Scooter Tour. Journal of Herpetology 27(2): 133143. The Timber Rattlesnake receives varying degrees of protection throughout its range in the United States. King. Protected public lands and privately owned nature preserves have contributed significantly to the conservation of Timber Rattlesnakes where they still exist (Ibid. Copeia 1948: 132. In Ontario, the Timber Rattlesnake has been assigned a rank of SX by the Natural Heritage Information Centre as apparently extirpated from Ontario (Oldham, 1997). Contributions of the Royal Ontario Museum Life Sciences 53: 192. 1950. Biological Conservation 15: 1358. Devil's Hole State Park. Female snakes usually do not eat during gestation. Other studies also support the contention that the Timber Rattlesnake consumes small mammals almost exclusively (Schmidt and Davis, 1941). Ovulation occurs from late May to early June, while maximum spermatogenesis is reached in July, continuing through September (Aldridge and Brown, 1995; Martin, 1993). Growth rates and size of newborns appears to be highly variable geographically, and Brown (1991) presents a table summarizing both growth rates and minimum age of first reproduction of Timber Rattlesnakes throughout their range. Top 5 Ways to Experience the Niagara Gorge Indoor Things to Do in Niagara Falls on a Rainy Day Enjoy a Glass at The Best Wineries in . Copperhead. 1996. White footed mice (Peromyscus leucopus) and redbacked voles (Clethrionomys gapperi) comprised the bulk of the diet of one sample, at 65% and 20% respectively (Ibid.). Timber Rattlesnakes prefer areas not frequented by people (Ditmars, 1907; Anderson, 1965), although few such sites still exist (DeGraaf and Rudis, 1983). Herpetological notes from southeastern Texas. 229 pp. Copeia 4: 230. Her Majesty the Queen in Right of Canada, 2010.Catalogue No. In Ontario, the Natural Heritage Information Center determined that the Timber Rattlesnake is extirpated, the chance of rediscovery being very small. The area around Niagara Falls is home to a wide variety of wildlife, including mammals, bird, reptiles and amphibians. Thompson. The climb up Shortoff Mountain is 1,500 feet in about a mile. Data Deficient (DD)*** A category that applies when the available information is insufficient (a) to resolve a species eligibility for assessment or (b) to permit an assessment of the species risk of extinction. $45.00. Barton, A.J. 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). Herpetological Review 25(2): 70. 1950. Snake hunters report that it is not difficult to hunt out (i.e. During courtship, the male repeatedly strokes the neck region of the female with his chin (Anderson, 1965). Sutherland, I.D.W. Spring emergence is likely affected, but not completely determined, by temperature (Galligan and Dunson, 1979). Herpetologica 9: 49-56. In Galligan and Dunson, 1979 (above). Males migrate further than females, likely to search for mates. I have been hiking the Lake George region for the past several years and have not come upon any rattlesnakes, however I did hear there were numerous snakes at Buck Mountain last year. In Logier, 1925 (above). COSEWIC Mandate The Committee on the Status of Endangered Wildlife in Canada (COSEWIC) determines the national status of wild species, subspecies, varieties, and nationally significant populations that are considered to be at risk in Canada. Habitat: They are found in field areas, wetlands and edges of moist forests. 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 last Timber Rattlesnake sighting was in the Niagara Gorge, Ontario in 1941 (Ontario Herpetofaunal Summary [OHS], unpubl. and F.W. Additionally, some snake hunters claim that Timber Rattlesnakes will not leave the den until they have shed (Ibid.). Biology, status and management of the Timber Rattlesnake (Crotalus horridus): a guide for conservation. Fitch, H.S. Harwig, S.H. Although the Timber Rattlesnake was proposed for listing under Appendix II of the CITES Convention in 1997, the proposal was not adopted because it was argued that international trade was minimal, and that the species would benefit more by increasing protection in the United States (Ibid.). Spend a few hours out on the rocks testing your strength. . I normally would. Translocated males have significantly larger activity ranges, range lengths and mean distances moved per day than native males (Rupert and Reinert, 1992). COSEWIC HistoryThe Committee on the Status of Endangered Wildlife in Canada (COSEWIC) was created in 1977 as a result of a recommendation at the Federal-Provincial Wildlife Conference held in 1976. Although some of the snakes in this region are very common, many of these snakes are endangered and at risk. The milksnake usually never reaches more than one meter in length (Yagi et al., 2009). Feb. 14A 5-year-old boy rescued from the Niagara Gorge Monday afternoon remains in critical condition at Oishei Children's Hospital in Buffalo. Journal of the Pennsylvania Academy of Science 65 (Suppl. 3. 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). ** Formerly described as Not In Any Category, or No Designation Required.*** Formerly described as Indeterminate from 1994 to 1999 or ISIBD (insufficient scientific information on which to base a designation) prior to 1994. The maximum single migratory movement away from a den was 7.2 km for a male in the same population. A woman died, and her 5-year-old son miraculously survived, when the pair plummeted 90 feet from New York's famed Niagara Falls in what authorities have said does not appear to be an accident . Martin, W.H. The last recorded sighting of a Canadian timber rattlesnake was in 1941, in the Niagara Gorge. Collins, J.T. 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. Herpetologica 14: 2324. Timber Rattlesnakes (Crotalus horridus) of the Pine Barrens: their movement patterns and habitat preference. Sex ratio in a New Jersey brood was 1:1 (Odum, 1979). 22 pp. Though they are mostly active by day, during a hot summer they may also be active at night. Brown, W.S. The Midget Faded Rattlesnake is only found in the Flaming Gorge area, but it's worth noting because it is far more deadly than most other rattlesnakes. Lutterschmidt, W.I. Gravid females did not contain any food items, while 30.3% and 35.0% of males and nongravid females, respectively, contained at least one food item. Timber Rattlesnakes may swim across lakes during their seasonal migrations (Neill, 1948), and small Timber Rattlesnakes have been found as high as 9 m in trees (Saenz et al., 1996). An introduction to the reptiles and amphibians of the United States. Populations of Timber Rattlesnakes are limited in the northern parts of their range by a small number of suitable nest sites. The reptiles of Ontario. Knight. A variety of habitats are traversed throughout the active season, depending partly on individual age and reproductive state. on wood turtles with Dr. Ron Brooks at the University of Guelph. Logier, Frank Ross, Craig Campbell and James Kamstra), but no Timber Rattlesnakes have been found (Ibid.). Timber Rattlesnakes are venomous. Fish and Wildlife Service is conducting a review of the Timber Rattlesnake for possible protection under the federal Endangered Species Act (Casper and Hay, 2001). and W.A. 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.). Newborn Timber Rattlesnakes have yellow on the lateral and ventral surfaces of their tails, but are not thought to use their tails as lures, as do other juvenile snakes with similar colouration (Neill, 1960). Patch, C.L. 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. They have been extirpated from the states of Maine and Rhode Island, and may be close to extirpation in New Hampshire (Brown, 1993). List of the Reptilia of Ontario. 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). Sections of the trail are paved while . Familiar amphibians and reptiles of Ontario. Rattlesnakes are not usually found above 6,000 feet in . In general, they are very mildmannered and will not strike unless provoked. Copeia 1988(4): 964978. 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). Dover Publications, Inc., New York. 4. Granitic escarpments and ledges with accumulations of talus are common features of den sites (Brown, 1991), the majority of hibernacula being found on south facing slopes (Galligan and Dunson, 1979). and D.D. Overcast. Journal of Herpetology 2: 107-112. Keenlyne (1972) studied the sexual differences of feeding habits of Timber Rattlesnakes in Wisconsin. Not at Risk (NAR)** A wildlife species that has been evaluated and found to be not at risk of extinction given the current circumstances. In a Kansas population, mortality was estimated at 45% in firstyear young, and 25% annually thereafter (Ibid.). Home Animals, Plants, Aquatic Life Amphibians & Reptiles Herp Atlas Project Species of Lizards and Snakes Found in New York Timber Rattlesnake Distribution Map. There are two big factors that make this hike so hard. Odum, R.A. 1979. Copeia 1998(2): 411422. Reinert, H.K. Timber Rattlesnakes can live 25 or more years in the wild. A local pastor is said to have captured a fourfoot specimen in his bare hands after chanting the magic words (Ibid.). 2. A Louisiana Timber Rattlesnake lived 36 years, 7 months and 27 days in captivity, reaching a total length of 1770 mm (Cavanaugh, 1994). Others doubt the negative impacts of increased shading, and believe that selective tree removal as a management strategy may actually do more harm than good (Reinert, pers. 2. Houghton Mifflin Company, New York. 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). Similarly in Virginia, the three leading foods were mice, chipmunks and cottontail rabbits (Uhler et al., 1939). Rattlesnakes are a member of this family. Rattlesnakes have the cat-like vertical pupils common to most venomous snakes unlike the round pupils of most non-poisonous snakes. Brown, W.S. The reptile book. The introduction of pigs into the countryside contributed to the demise of the Timber Rattlesnake; pigs are protected from envenomation by their thick layer of fat that prevents the venom from entering circulation, and thus are able to kill and eat rattlesnakes (Nash, 1908). It's common for rattlesnakes to be mistaken for gopher snakes, so you need to be able to tell them apart. The most distinctive behaviour of rattlesnakes in general is the use of the rattle itself. 1966. Hutchinson, R.H. 1929. 1925. Plourde, S.A., E.L. Szepesi, J.L. Copeia 1953: 212215. Parturition in the Timber Rattlesnake, Crotalus horridus horridus Linne. 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. Historical records are widely scattered and anecdotal and do not provide a clear picture of the species former abundance and distribution (Cook, 1999; see also Fig. A profile and impact assessment of organized rattlesnake hunts in Pennsylvania. SSAR Herpetological Circular No. 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. In 1978, COSEWIC designated its first species and produced its first list of Canadian species at risk. American Zoologist 28(4): 195A. A production note will be provided if additional information on the status report history is required. comm. Timber Rattlesnakes generally begin to rattle when approached within 12 m (Barbour, 1950). 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). 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). Located deep in the Niagara Gorge, stairways lead to four kilometres (2.5 miles) of rugged hiking paths that wind through this pristine pocket of Carolinian Forest, past prehistoric geological formations, wild flora and fauna. The designation of status for the Timber Rattlesnake is quite straightforward: it has not been reported in this country in almost 60 years. xvi + 378 pp. 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). 1956. Weller, W. 1982. Palmer, J.R. Bailey and J.R. Harrison. 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). Clearly, the potential impacts of human persecution are enormous. 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). Herpetological Review 27(3): 145. Endangered (E) A wildlife species facing imminent extirpation or extinction. Herpetological Review 25(4): 166. Sadighi et al. Police believe the 34-year-old woman and 5-year-old boy intentionally jumped 90 feet into the frozen gorge below after climbing over a rail. 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. 1980. comm. The foraging behaviour of Timber Rattlesnakes was studied in detail in Pennsylvania (Reinert et al., 1984). Burgdorf, D.C. Rudolph and C.M. The pits enable the snake to sense warm-blooded animals and even tell the size of the animal. Rattlesnake Point near Milton, Ontario The Niagara River over thousands of years carves the Niagara Gorge over and through the Niagara Escarpment The Niagara Escarpment is a long escarpment, or cuesta, in Canada and the United States that runs predominantly east-west from New York through Ontario, Michigan, Wisconsin, and into Illinois.
