In a subsequent detailed evaluation, Alberta’s Endangered Species Conservation Committee (ESCC) further identified the prairie
rattlesnake as Data Deficient in 2001. See information on the Endangered Species Conservation Committee and the species
assessment process at:
Intentional killing of rattlesnakes by humans, road and pipeline construction, and increased agricultural activities within
the traditional range for this species have contributed to declines in population in various localities in Alberta.
Rattlesnakes are drawn to the heat of road pavement at night, making them more vulnerable to being killed by traffic, or
more likely to be found by those who wish to harm them intentionally.
The prairie rattlesnake is designated as a non-game animal in the Province of Alberta. It is illegal to kill, possess, buy
or sell rattlesnakes in Alberta. Anyone who is concerned about having this species on their property should contact their
local Fish and Wildlife office.
Nature's Heat Seekers
Adult rattlesnakes locate warm-blooded prey through the use of two heat-sensing organs called facial pits, situated between
the snake’s eyes and nostrils.
