Field observation of the association of adult and neonatal timber rattlesnakes, Cortalus horridus,  with possible evidence of conspecific trailing. It can be identified by its dark chevron markings and the rattle, but it can have one of two different background colors – … In the context of species at risk conservation, recovery is the process by which the decline of an endangered, threatened, or extirpated species is arrested or reversed, and threats are removed or reduced to improve the likelihood of the species’ persistence in the wild. 9:49-56. Typically they emerge in early to mid-May and enter hibernation generally in mid September to early October but may stay out as late as November (Brown 1993).

Cavanaugh, C.J. In Preparation. They are also known to hibernate communally, putting them at risk of being captured or killed by poachers, or susceptible to catastrophic loss due to land development (Odum 1979). The last known collection was in the Niagara Gorge -specifically, the Niagara Glen- in 1941 (Cook, 1999). The Snakes of Canada (McClelland and Stewart, 1972). Specific summer habitat requirements differ according to sex (Brown 1993; Smith 2001; Ewing 2003). NatureServe. However, the impacts of increased shading are not entirely understood, with some suggestions that selective tree removal may actually harm the snakes more (Smith 2001). Beyond the Niagara area, the extent of the historic distribution of the timber rattlesnake in very unclear. Toner. Fortunately, the popularity of these is declining (Brown 1993). The timber rattlesnake, which has an unmarked, triangular head and vertical pupils, is heavy bodied and can grow to almost two metres in length.

Conservationalist. The snake’s venom is harmful to humans, especially small children who are more sensitive to the venom due to their small size (Guidry 1953), and it has a reported striking distance of 46 cm (Ditmars 1907). Habitat restoration techniques – creation of hibernacula, artificial birthing sites, etc. This snake hibernates communally in rock slides and on ledges and outcrops, usually those that face south. Heat-sensitive facial pits between each eye and nostril enable them to sense minute thermal changes in the infra-red range that … No. Habitat loss through urban development, logging, and aggregate extraction reduces the amount of available habitat for the species, leading to population declines (Wright and Wright 1957, Weller 1982). The natural progression of forest succession may be incompatible with the long-term survival of timber rattlesnakes, if the canopy cover results in too much shade (Brown 1993). There is very little information specific to dens historically found in Ontario, although two potential den sites – one in Spencer Gorge below Dundas Peak and the other in Medad Valley – are noted by Lamond (1994). refers to timber rattlesnakes in New Jersey as inhabiting ‘flat forested country back of the central coast, [and] quite damp in spots’.
