Facts About Plains Garter Snakes

Geographic Location

The Canadian provinces of Saskatchewan, Manitoba, and Alberta and the American states of Wyoming, Wisconsin, Texas, South and North Dakota, Oklahoma, Ohio, New Mexico, Nebraska, Montana, Missouri, Minnesota, Kansas, Iowa, Indiana, Illinois, and Colorado comprise the North American range of this snake.


This snake can be found in former prairies of black soil, vacant lots, marshes, wet meadows, pastures, mammal burrows, road embankments, underneath rocks and logs, and cultivated fields.


This snake can tolerate cold weather, and often likes to bask on warm winter days. This is a docile snake and does not bite easily when handled. These snakes feed on small amphibians, slugs, carrion, birds eggs, mice, salamanders, fish, and earthworms. As active thermo-regulators, they bask and feed alternatively throughout a particular day.


The mating months for the Plains Garter Snake are April through May, which results to five to thirty hatchlings, in the months of August to early October. These newborns are about fifteen to twenty five centimeters long.


They feed through overpowering prey using their strong jaws, as they are non-venomous and are not constrictors. When confronted by danger, they wag and raise their tails, and hide their head under coils they form with the rest of their bodies. Sometimes, they release excrement and musk are released to discourage new people.
