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. The Canadian FieldNaturalist 29(5): 9195. and D.D. The distribution and status of the New Jersey Timber Rattlesnake including an analysis of Pine Barrens populations. You will not receive a reply. The cessation of feeding was apparently induced by the development of large offspring. Males and nongravid females utilize forest habitat with greater than 50% canopy closure, thick surface vegetation and few fallen logs (Reinert and Zappalorti, 1988b). Extirpated species and their habitat are protected if the species are again found in Ontario. Ministry of the Environment, Conservation and Parks. It arose from the need for a single, official, scientifically sound, national listing of wildlife species at risk. Conservationist 36: 2729. COSEWIC Secretariatc/o Canadian Wildlife ServiceEnvironment CanadaOttawa, ONK1A 0H3, Tel. 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. The species is still found in Alabama, Arkansas, Connecticut, District of Columbia, Delaware, Florida, Georgia, Iowa, Illinois, Kansas, Kentucky, Louisiana, Massachusetts, Maryland, Minnesota, Mississippi, Missouri, North Carolina, New Hampshire, New Jersey, New York, Ohio, Oklahoma, Pennsylvania, South Carolina, Tennessee, Texas, Virginia, Vermont, Wisconsin and West Virginia (Casper and Hay, 2001; Harding, 1997). Sheds can be measured directly by painting the rattle and then counting unpainted segments upon recapture (Brown, 1991). 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 Wisconsin, bounty records showed a 7080% decline over a sevenyear period (Casper and Hay, 1998). 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). Journal of Herpetology 27(2): 133143. 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). Female snakes usually do not eat during gestation. There are more than 24 rattlesnake species and all of them have that most-famous feature: the rattle! Cavanaugh, C.J. 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). Cameron, Toronto, Ontario. The mean maximum migratory distance from the den was 4.07 km for males and 2.05 km for females in northeastern New York (Brown, 1993). Houghton Mifflin Company, New York.

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. Populations of Timber Rattlesnakes are limited in the northern parts of their range by a small number of suitable nest sites. 1990. Assessment based on a new status report. 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). 1986. Genetic variation and gene flow within and between local populations of the Timber Rattlesnake, Crotalus horridus. Herpetological Review 25(1): 28. The Timber Rattlesnake in the northeast: its range, past and present. 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).

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. Though they are mostly active by day, during a hot summer they may also be active at night. 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. Bushar. Sutherland, I.D.W. Historically, they have been subject to human exploitation, such as bounty hunting, collection and sport hunting. Brown, W.S.

Barbour, R.W. Herpetologica 39(4): 430436. Mating takes place in late summer (Martin, 1993) and young are born from late August to midSeptember (Galligan and Dunson, 1979). Hibernation is almost always communal, with only scattered reports of individuals hibernating singly (Neill, 1948; Odum, 1979). Sex independent ground colour in the Timber Rattlesnake, Crotalus horridus horridus. 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). Not at Risk (NAR)** A wildlife species that has been evaluated and found to be not at risk of extinction given the current circumstances. Distance: 4 km. 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). HERP Bulletin of the New York Herpetological Society 15(1): 2735. Overcast. Rudis. Zoos have reportedly been known to attach additional rattles on the end of broken ones to make them appear more impressive (Ditmars, 1907; Schmidt and Davis, 1941). The earliest record of Timber Rattlesnakes in what is now Ontario dates back to September 1669, where there is a reference in the journal of Rene de Brehart Galine, who was attached to M. de La Salles party (Logier, 1939). Morris, P.A. The varied patterns of flow across . The site also contains some of the best-exposed fossils you'll find in the entire Niagara Region. Brown, pers. Similarly, in a New Jersey litter of 13 born in captivity, one snakeling was born dead, and another had a birth defect that would prevent it from eating (Odum, 1979). Johnson, B.D., J. Hoppe, R.

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.
