Habitat In Canada, Bullsnake occurs in short- and mixed-grass prairie, commonly in association with brushy and sandy areas and around badlands along major river valleys. Is there an [observed, inferred, or projected] decline in index of area of occupancy? Owing to its coloration, dorsal pattern, and semikeeled scalation, it superficially resembles the western diamondback rattler (Crotalus atrox), which is also common within the same range. However, these types of events probably also create new hibernacula and thus have beneficial effects as well (Didiuk pers. The range of bull snakes includes Montana, North Dakota, Wyoming, South Dakota, Nebraska, Colorado, Kansas, Oklahoma, Texas, New Mexico, Missouri, Iowa, Minnesota, Wisconsin, Illinois, and Indiana. Edkins, T.L. Biodiversity/Species observation database. Regina, SK, Briar Howes Poulin. Phone conversation during Threats Calculator Assessment conference call for the Bullsnake.March 2016. [citation needed]. Comments from review of status report.December 2016. Hayland increased throughout most of Bullsnakes range in Saskatchewan (Figure 4b), whereas natural land decreased in most of the counties where the grid squares occur (Figure 4c). The Committee meets to consider status reports on candidate species. 
In Saskatchewan, most hibernacula have been located in unstable slump zones along the slopes of river valleys (e.g., Frenchman River Valley; Gardiner and Sonmor 2011; Martino et al. As for Great Basin Gophersnake in B.C. Bull snakes are egg-layers, and females deposit their eggs in burrows they excavate themselves or those abandoned by small mammals. You need a hbitat with the proper environmental conditions. Exotic Jungle. Saskatchewan NAWMP Partnership. Poulin, J.A. 2005. Canadian Wildlife Service [Observed, estimated, inferred, or suspected] percent [reduction or increase] in total number of mature individuals over the last [10 years, or 3 generations]. comm. Bullsnakes are active during the day, foraging mainly on small mammals. Wright, J.D. The distribution of the species in Alberta and Saskatchewan, as currently understood, suggests a degree of fragmentation based on habitat availability. ca. A comparison of herpetofauna and small mammal diversity on black-tailed prairie dog (Cynomys ludovicianus) colonies and non-colonized grasslands in Colorado. COSEWIC Secretariat There was a slumping event at a large den in Grasslands National Park (Gardiner and Sonmor 2011). Threatened by traffic mortality, direct persecution, and habitat loss.. There is habitat connectivity across the international border to Montana along the many drainages of the Milk River (Didiuk pers. Environment Canada Saskatchewan NAWMP Implementation Plan 20012026: Five Year Plan April 2007 April 2012. Bull snakes are nonvenomous and can be found in sandy open country and in pine barrens of western North America, from British Columbia, Canada, south to northern Mexico and from California east to Indiana. COSEWIC would like to acknowledge Rob Willson for writing the the status report on Bullsnake (Pituophis catenifer sayi) in Canada, prepared under contract with Environment and Climate Change Canada. It is illegal to kill or collect this species by law in Iowa. Ottawa. Kapfer et al. Since the 2002 COSEWIC report, two surveys of road mortality focusing on snakes, including the Bullsnake, have been conducted in Alberta (Martinson 2009) and in Saskatchewan (Fortney et al. 157158. Their typical coloration is yellowish brown or cream-coloured, with dark blotches. Commonly considered a prairie species, it also occurs in pastures, old fields, savannas, and along some river bluffs. COSEWIC Secretariat Bullsnakes, however, are not fast movers and often must take other defensive actions. They are related to pine snakes (Pituophis melanoleucus) of the eastern and southern United States and the Mexican bull snake (P. deppei) of north-central and western Mexico. 2016). Dont get a venomous snake, especially if this is your first pet snake. The species relies on communal wintering dens, which may be scarce on the landscape. [citation needed], Bullsnakes can sometimes be mistaken for rattlesnakes and killed. Canadian Wildlife Service The bullsnake was once considered Iowas most No warranty, expressed or impli ed, is Analysis not completed due to lack of data. NatureServe (2016) indicates the following status designations for Bullsnake: Global--G5T5; National for U.S.A--N5; National for Canada--N4; Subnational for Alberta--S3 (Vulnerable); Subnational for Saskatchewan--S4 (Apparently Secure). Additional investigations of snake ecology and conservation include eight years working on Eastern Massasaugas and Eastern Hog-nosed Snakes in Ontario. Of 25 females encountered over a 5-year period at an Alberta site, the smallest gravid female was 112 cm SVL, its age was unknown (Wright 2008). The calculated value based on all compiled records was 952 km2. Females are larger than males but males have larger cirri. Parks Canada The species is especially vulnerable to increased mortality because of its low abundance, late maturity, and low rate of productivity. Only a small portion of the snakes would be affected by military traffic and activities. Bull snakes also mimic rattlesnakes by. In 1978, COSEWIC designated its first species and produced its first list of Canadian species at risk. No Aboriginal Traditional Knowledge was accessible at the time of the preparation of this report (Jones pers. They are mainly fossorial (burrowing); however, they often cross open land and climb trees in search of prey, which is mainly rodents but also includes birds and lizards. Somers, C.M. As recognized for other communally hibernating snakes (e.g., Great Basin Gophersnakes; COSEWIC 2013), aggregations of individuals at hibernacula in the spring are most vulnerable to persecution. The most intensive studies of Bullsnake in Canada have been conducted in the Frenchman River Valley in southern Saskatchewan. (Caution: Read Before You Try!). Given current fire suppression practices, the scope was determined to be somewhere near the middle or lower end of range. Effects of off-road vehicles on reproductive success of pine snakes (Pituophis melanoleucus) in the New Jersey pinelands. When threatened by anything as large as a human, a bullsnake's next defensive action is to rear up and make itself look as large as possible, while at the same time hissing at the perceived threat. 
Call participants were uncertain of any future development plans. In Alberta, Bullsnakes are protected as a non-game animal under the provincial Wildlife Act, which makes it illegal to kill, possess, buy or sell snakes native to Alberta. Prairie Conservation: a bulletin from the Alberta Prairie Conservation Forum. Is there an [observed, inferred, or projected] continuing decline in number of mature individuals? While many occurrences in Saskatchewan appear to be separated by distances that are beyond normal movement capabilities of Bullsnakes (e.g., 10s of km separating Big Muddy, Frenchman, and South Saskatchewan river valleys), others, particularly in eastern Alberta are relatively close together (within a few km or closer), suggesting habitat connectivity. Edmonton, Alberta. Check Elk/Bear Permit Application Results, Managing Invasive Species in Your Community, Wildflowers, Grasses and Other Nonwoody Plants. [6] Possibly being the largest subspecies of gopher snake on average, mature specimens can have an average weight in the range of 11.5kg (2.23.3lb), though the heavier known specimens can attain 3.64.5kg (7.99.9lb), with larger specimens being quite bulky for a colubrid snake. The bullsnake was once considered Iowas most 2016. Although there is evidence of genetically discrete subpopulations, it is currently unknown whether the level of genetic differentiation has been sufficient to generate local adaptations that would warrant multiple designatable units.

It also adopts a rattlesnake-like "S-curve" body posture as though about to strike. You will not receive a reply. 2015. Bullsnake habitat within the National Wildlife Area of CFB Suffield is also protected. Mike currently lives in New Haven County, CT where he has been studying herpetology (the study of Amphibians & Reptiles) for many years and has worked with state agencies, private agencies and zoos doing herp field work and teaching the public about snake safety and the importance of amphibians and reptiles in the ecosystem. However, large areas in southwestern Saskatchewan and Alberta are private lands, and trespassers are actively discouraged, and thus many areas are not visited by recreational users (Didiuk pers. The only national park where Bullsnakes are known to occur is Grasslands, whereas they occur in several provincial parks: Dinosaur and Writing-on-Stone Provincial Parks in Alberta and Saskatchewan Landing Provincial Park. Landslides occur sporadically throughout the Bullsnakes range in steeply sloped areas where hibernacula are located. Alberta Environment and Parks (AEP). Mike now focuses on herp education through social media and public programs. Regina, SK, Jennifer Rowland The Bullsnake is the only subspecies without the name gopher attached to it ; this often leads to confusion and many people believe the bullsnake is a completely separate species, which is not the case. COSEWIC Committee on the Status of Endangered Wildlife in Canada, COSEPAC Comit sur la situation des espces en pril au Canada. The International Union for Conservation of Nature and Natural Resources (IUCN) classifies the bull snake as a species of least concern. These defensive behaviors are meant to scare away threats, however, and not to sound an attack. 33 pp. Whitaker, P.B., and R. Shine. Distinguishing features include a narrow scale at the tip of the snout that is raised above the nearby scales, a dark line that crosses the head in front of the eyes, a dark band from the eye to the angle of the jaw, and a dark vertical spot below the eye. Martinson, A. Alberta Environment and Sustainable Resource Development. Some species are quite common, while others are very rare. A number of factors make Bullsnakes susceptible to road mortality, namely their use of road-side features as habitat (Fortney et al. Their typical coloration is yellowish brown or cream-coloured, with dark blotches.
