Niagara River Habitat Conservation Strategy Completed in 2014,this document identifies critical habitats and priority actions for the 900,000+ acre Niagara River watershed. Francis Cook graciously allowed me to include information contained in his unpublished Timber Rattlesnake account in his upcoming book, The Natural History of Amphibians and Reptiles in Canada. In both provinces, the snakes were exterminated by hunting parties killing the snakes at their dens, habitat loss, and hog farming using pigs to eradicate the snakes, until they had been wiped out across Canada. Reptiles and amphibians: Eastern and Central North America (3rd Edition). Journal of Herpetology 16(2): 145150. They are seasonally migratory -- from the den site to the summer habitat and back again. 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). Some rattlesnake terrain in the Bend and Central Oregon Region: Smith Rock State Park, Alder Springs/Lower Wychus Creek, Lake Billy Chinook, the Lower Deschutes River, Prineville Reservoir, Any riparian area that is below 3,000 feet in elevation. There have also been scattered reports of Timber Rattlesnake sightings in extreme southern Quebec along the U.S. border. It was an old specimen measuring 56 inches in length as this one was such an old specimen and as no others have been taken there in recent years, Mr. Patch was of the opinion that it was the last of its race. Mansell, and P.E. Bushar. Brown, pers. 1991. The first shedding of maxillary fangs takes place at a very early age, as evidenced by the fact that newborns have been found with fangs in the functional position (Barton, 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. 1996. Opinion varies as to whether females give birth at den sites or at maternity rocks some distance away (Galligan and Dunson, 1979). This species was last sighted in Canada in 1941. Her Majesty the Queen in Right of Canada, 2010.Catalogue No. The famous rattle noise comes from . Kim Smith completed her Honours B.Sc. We also coordinate Ontarios actions on climate change in the name of healthier communities, ecological protection and economic prosperity. 1953. 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). 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. When the calm meets the storm: the White Water Walk is the tourist trail following the Great Gorge. The most important habitat component of northern Timber Rattlesnakes is the communal den within which hibernation takes place. Many translocated snakes immediately leave the area in which they are released (Galligan and Dunson, 1979). 1993. In Pennsylvania, newborns ranged from 220280 mm snoutvent length (SVL) (Galligan and Dunson, 1979). The rattlesnake has such a legacy there that in the late 20th Century there was a professional lacrosse team named the Rattler's. This despite the rattlesnake has not been seen in the City of Rochester for many decades prior. American Zoologist 28(4): 195A. Herpetologica 12: 326. Quarterly Journal of the Florida Academy of Sciences pp. In general, they do not strike unless provoked, preferring instead to remain concealed (Ditmars, 1907). 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). DeGraaf and W.R. Danielson. Matthews. Timber Rattlesnakes may be active by day or night; nocturnal activity is especially common during hot summer nights (Martof et al., 1980). 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). The specific Latin name horridus means dreadful, in reference to the venomous nature of the Timber Rattlesnake (Collins and Knight, 1980). The now extinct Timber Rattlesnakes were once common to the area, and where much feared by locals. The committee meets to consider status reports on candidate species. Rattlesnakes prefer to eat mammals, especially mice, squirrels, woodrats and chipmunks. Distance: 4 km. The climb up Shortoff Mountain is 1,500 feet in about a mile. Characteristics of venom from the rattlesnake Crotalus horridus atricaudatus. Niagara Glen Add to Itinerary. 1961. The Timber Rattlesnake is a heliothermic species, with the ability to regulate its temperature by radiation absorption throughout its daytime activities (Odum, 1979). Occasional papers of the Museum of Natural History, University of Kansas 118: 1-11. 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. Toner. 1995. La Socit Zoologique de Qubec. CW6914/1112002EINISBN 0662318803. 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.). Herpetological Review 25(2): 70. The site also contains some of the best-exposed fossils you'll find in the entire Niagara Region. Galligan, J.H. A mother is dead and her 5-year-old son is in critical condition after they both fell "approximately 90 feet" into the Niagara Gorge at the Niagara Falls State Park earlier this week, authorities . Foregoing reproduction in some years is apparently necessary to allow females to gain weight and store yolk protein in the developing eggs (Galligan and Dunson, 1979; Brown, 1981). 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. Reinert and L. Gelbert. Proceedings of the Ninth Annual Meeting of the Ohio Herpetological Society 5: 163. Specific summer habitat requirements differ according to sex and age class. This species occurs throughout the eastern and central United States, although it is locally extirpated in many areas. Mlanon, C. 1950. Fitch, H.S. Keenlyne (1972) studied the sexual differences of feeding habits of Timber Rattlesnakes in Wisconsin. 2). 2001. The Niagara Region is home to 14 snake species excluding those who have become extinct. Journal of Herpetology 2: 107-112. Dundee, H.A. Mean body temperature during this time was 26.9C (Ibid.). Natural Heritage Resources of Ontario: amphibians and reptiles. Female reproductive ecology in a northern population of the Timber Rattlesnake, Crotalus horridus. 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. Clearly, the potential impacts of human persecution are enormous. 1985. Comstock Publishing Associates, Cornell University Press, Ithaca, New York. Copeia 1988(4): 964978. Schaeffer, G.C. Winds SW at 10 to 20 mph.. Tonight Notes on a litter of young Timber Rattlesnakes. Timber Rattlesnakes are seasonally migratory, from den to summer range and back (Brown, 1993). 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. 1972. and for their rattles (Anderson, 1965). Hibernation of amphibians and reptiles in Richmond County, Georgia. Other studies also support the contention that the Timber Rattlesnake consumes small mammals almost exclusively (Schmidt and Davis, 1941). Logier, Frank Ross, Craig Campbell and James Kamstra), but no Timber Rattlesnakes have been found (Ibid.). Rattlesnakes documented in Grand Canyon National Park Birds Keen birdwatchers will be delighted to know that the Niagara region hosts more than 300 bird species. . Minor range extensions have been reported relatively recently in Virginia (Martin et al., 1992), Louisiana (Lutterschmidt, 1992; Dundee, 1994b) and Florida (Jenson et al., 1994). Food of snakes of the George Washington National Forest, Virginia. 1994. The last Timber Rattlesnake sighting was in the Niagara Gorge, Ontario in 1941 (Ontario Herpetofaunal Summary [OHS], unpubl. The rattle is the most obvious behavior of these snakes, apparently used when the individual feels angry or threatened. 1950. The copperhead is one of three New York snakes whose bite is poisonous. Bounty records from one county in Minnesota declined from 4,955 in 1980 to 191 in 1987 (Ibid.). Ministry of the Environment, Conservation and Parks. Herpetological Review 25(1): 3334. A number of populations from New York appear to have been extirpated, primarily because of overhunting (Brown, 1981). A woman is dead after plunging into the Niagara Gorge with her 5-year-old son Monday in what officials believe was a deliberate act. Uhler, F.M., C. Cottam and T.E. and R.T. Zappalorti. State Park Police said their dispatchers received "multiple calls", at about 12:30 p.m., reporting that an "adult female and her child fell into the Niagara Gorge between Terrapin Point and the Cave of the Winds." Crotalus horridus (Timber Rattlesnake). Threatened (T) A wildlife species likely to become endangered if limiting factors are not reversed. 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). Due to their appearance and frightening actions, people assume snakes to be dangerous (Edward & Foote, 1979). Low 37F. Casper, G. and R. Hay. Gopher Snakes or Bullsnakes (Pituophis melanoleucus) grow large and bulky. Reinert and L. Gelbert. Garnier, J.H. 1939. Rattlesnakes are found from southern Canada to central Argentina but are most abundant and diverse in the deserts of the southwestern United States and northern Mexico. Burgdorf, D.C. Rudolph and C.M. Average shedding rate of Timber Rattlesnakes in northern New York was 1.44 sheds per year (Brown, 1988), compared to two sheds per year in Kansas (Fitch, 1985). Female snakes usually do not eat during gestation. In Logier, 1925 (above). In Cook, 1999 (above). L.K. Mountain Lion . Foraging success and the ability of females to regain mass may be the main determinant of the length between successive reproductive events (Brown, 1991). A 5-year-old was rescued Monday after he and his mother jumped into the Niagara Gorge in Niagara Falls State Park. Herpetologica 9: 49-56. 1919. Cover illustration/photo:Timber Rattlesnake -- Illustration by Marisa Bonofiglio, Woodbridge, Ontario. Patch, C.L. Figure 1. Hibernation in the northern parts of the Timber Rattlesnakes range occurs in the cracks of rocky ledges, usually facing south (Odum, 1979). The most recent confirmed records of this rattlesnake in Ontario are from the Niagara Gorge in the 1940s. 1972. 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. Several biological traits of the Timber Rattlesnake greatly reduce its ability to recover from largescale losses of adults in a population. i-iv + 178. Conserving the Timber Rattlesnake. Observations on gravid females in captivity also indicated that the snakes did not feed during gestation (Odum, 1979). Now go up the Genesee River and the probability of finding a rattlesnake goes up dramatically. Time: 1 - 2 hours. Jensen was moving cows when he spotted a rattler. Rattles are vibrated sideways at about 48 cycles per second (Schmidt and Davis, 1941). Hibernation is almost always communal, with only scattered reports of individuals hibernating singly (Neill, 1948; Odum, 1979). You will not receive a reply. WGRZ.

Crotalus horridus (Timber Rattlesnake) coloration. Larson and T.H. Timber Rattlesnakes are considered the most mildmannered of any of the North American rattlesnakes, and individuals usually do well in captivity (Ditmars, 1907; Anderson, 1965; Morris, 1974). The head is triangular with a distinct neck. COSEWIC assessment and update status report on the Timber Rattlesnake Crotalus horridus in Canada. Venom is clear and watery in newborns, becoming bright yellow and concentrated as the snake matures (Johnson et al., 1968). Rattlesnakes can be found in woodlands, plains, deserts, foothills, and marshes. Palmer, J.R. Bailey and J.R. Harrison. University of Missouri Press, Columbia, Missouri. Ditmars, R.L. Weller. By the early 1970s, the Timber Rattlesnake had been nearly extirpated in all but the most remote sections of the United States (Morris, 1974). Variation in venom samples from copperheads (Agkistrodon contortrix) and Timber Rattlesnakes (Crotalus horridus). Johnson, B.D., J. Hoppe, R. Rogers and H.L. Unpublished Timber Rattlesnake account in The Natural History of Amphibians and Reptiles in Canada. Timber Rattlesnakes produce stillborn young and abort infertile eggs at a frequency of about 20% (W.S. Niagara Falls, NY (14301) Today. 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. On June 5, 2003, the Species at Risk Act (SARA) was proclaimed. : extirpated 1993 Brown: probably extirpated [from Ontario]1999 Cook: almost certainly extirpated in Canada. to Fitch, 1985). 1980. Over the years it has become a thriving ecosystem home to birds, fish, turtles, snakes and more! 1994a. Sadighi et al. and F.W. The colouration at the tip of the tail becomes noticeably dark. Males grow considerably longer and heavier than females, and there is no apparent reproductive advantage for females obtaining a larger body size (Gibbons, 1972). The practice of paying bounties on Timber Rattlesnakes in New York ended in 1971 under the Fish and Wildlife Law (Brown, 1981). 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). Neill, W.T. 1989. If the rattle becomes accidentally lost, the end of the tail remains blunt, never pointed (Ibid.). Male Timber Rattlesnakes reach maturity at an average age of 5.3 years in northeastern New York (Aldridge and Brown, 1995) and 4 years in South Carolina (Gibbons, 1972). Rattlesnakes are deaf to the sound of their own rattles, and are thought to use them when angry or threatened (Ditmars, 1907). Greene and J.B. Friedlaender. 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. Crotalus horridus (Timber Rattlesnake) reproductive phenology. This is a remote area and there are use trails across Washington Department of Natural Resources land, but private land is all . COSEWIC Secretariatc/o Canadian Wildlife ServiceEnvironment CanadaOttawa, ONK1A 0H3, Tel. 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 natural lifespan of the Timber Rattlesnake in the northern part of its range is approximately 25 years (Brown, 1993). Length: 9.1 mi Est. The caudal lure of various juvenile snakes. Stechert, R. 1982. on wood turtles with Dr. Ron Brooks at the University of Guelph. Funding provided by the Canadian Wildlife Service, Environment Canada. the Ministry of Natural Resources and Forestry tracks species at risk such as the Timber rattlesnake; try to develop an appreciation for snakes; they play an important role in our environment; whether in a field or in your backyard, if you come across a snake, keep in mind that you are much larger than it is and the snake is more afraid of you than you are of it, if you come across a snake, please dont try to capture it, handle it or kill it; snakes can be delicate and improper handling can cause serious injury; also, certain species are protected under legislation, which makes it illegal to harass, harm or kill them; be respectful and observe from a distance, watch for snakes that may be crossing roads between May and October; road mortality is a serious threat to snakes because they are slow moving, hard to see on the road and are sometimes intentionally run over; if it is safe to do so, help snakes across the road in the direction they were headed, private land owners have an important role to play in species recovery; you may be eligible for stewardship programs that support the protection and recovery of species at risk and their habitats, report poaching of snakes and other animals to, volunteer with a local nature club or provincial park to participate in surveys or stewardship work focused on species at risk, this rattlesnake is a sit and wait predator; it frequently coils up adjacent to a small mammal scent trail and may wait for several days for the unsuspecting small mammal, individuals return to the same hibernation site year after year, although the Timber rattlesnake is venomous, there are few records of human fatalities; More people die every year from insect stings than rattlesnake bites. Knight. Identifying a Gopher snake starts by approaching it with caution. As there have been no recorded observations of the Timber Rattlesnake in almost 60 years, it is assumed not to exist in Canada. 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. Harold McNeil.
