The most important habitat component of northern Timber Rattlesnakes is the communal den within which hibernation takes place. Crotalus horridus (Timber Rattlesnake). A naturalist working for the Western New York Land Conservancy as part of the "Restore the Gorge" project discovered a rare species of cicada clinging to a Carolina rose in the Niagara gorge . Kim has also written COSEWIC status reports on the queen snake (Regina septemvittata) and the northern ribbon snake (Thamnophis sauritus septentrionalis). A Louisiana Timber Rattlesnake lived 36 years, 7 months and 27 days in captivity, reaching a total length of 1770 mm (Cavanaugh, 1994). Additionally, some snake hunters claim that Timber Rattlesnakes will not leave the den until they have shed (Ibid.).

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.). They have been extirpated from the states of Maine and Rhode Island, and may be close to extirpation in New Hampshire (Brown, 1993). Ovulation occurs from late May to early June, while maximum spermatogenesis is reached in July, continuing through September (Aldridge and Brown, 1995; Martin, 1993). 300 pp. 1996. Keenlyne (1972) studied the sexual differences of feeding habits of Timber Rattlesnakes in Wisconsin. Migration distances of males in general are greater than those of females because they actively engage in seeking mates (Reinert and Zappalorti, 1988b). Herpetological Review 26(4): 189190. Niagara Fishing ; Fishing Forum ; Rattlesnake Article The Journal of Heredity 87(2): 152155.

Timber Rattlesnakes in South Carolina reached lengths of 650750 mm SVL by the end of their second summer (Gibbons, 1972). New York State Park Police report that the youth has undergone surgery. 1950. Ironically, the food habits of the Timber Rattlesnake make it an economically valuable species which, were it not for its venomous nature, might actually have been encouraged to set up residence in Ontario (Logier, 1939; Martof et al., 1980). A variety of habitats are traversed throughout the active season, depending partly on individual age and reproductive state. 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. The 5-year-old boy who survived a 90-foot fall into the Niagara Gorge at Niagara Falls State Park on Monday after his mother jumped with him from above is in critical condition following. 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).

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).

It also provides some amazing unobstructed views of the southernmost section of the Niagara Gorge. 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).
