From easy to challenging trails - including steep stairways and a little boulder hopping, hiking is recommended between April and mid-November. Rattlesnakes, Vols. A population is defined by its den, which is critical to the survival of the entire population (Brown, 1993). 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). 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).

Thus, the persistence of Timber Rattlesnakes in that area of the Niagara region seems highly unlikely. 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.).

The winter habitat is primarily the den, which is located on a south facing rocky outcrop. Rattlesnakes documented in Grand Canyon National Park Designations are made on all native species for the following taxonomic groups: mammals, birds, reptiles, amphibians, fish, lepidopterans, molluscs, vascular plants, lichens, and mosses. Schmidt, K.P. 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. .

Timber Rattlesnakes collected during organized roundups are often released far away from their point of capture, and this action most likely leads to the death of the snake, because of its unfamiliarity with its surroundings (Brown, 1993). COSEWIC status reports are working documents used in assigning the status of wildlife species suspected of being at risk. Distribution and status of the herpetofauna of central region, OMNR. Duran. 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).
