The N.W.T. Department of Environment and Climate Change (ECC) has observed a decrease in the number of bison collisions on roads in the region. Between 2021 and 2025, there were 60 recorded collisions with bison, but in 2026, only one collision has been reported so far.
Terry Armstrong, a Bison Ecologist at ECC, credits the decline in collisions to wildfires impacting bison behavior. He explains that following wildfires, bison tend to shift their habitat, seeking out newly burnt areas for vegetation. This change in behavior may be diverting more bison away from roads, resulting in fewer collisions.
Wood bison, classified as a threatened species both locally and nationally, have a population estimated to be over 2,500 individuals according to ECC. Collisions between 2021 and 2025 led to the deaths of at least 76 bison, with the majority of incidents occurring along Highway 3.
August through September marks the rutting season for bison, increasing the likelihood of encountering aggressive behavior from the animals on roads. Armstrong warns that during this period, bison may be preoccupied with mating and territorial disputes, posing a risk to drivers.
As the region transitions into darker months, visibility decreases, heightening the risk of collisions with bison. Armstrong advises drivers to exercise caution, maintain a safe distance from bison, and refrain from actions that could startle the animals. It is crucial to remember that bison are formidable creatures and should not be approached or provoked.
Armstrong emphasizes the importance of coexisting safely with bison, highlighting their significance as North America’s largest land mammal and urging respect for these iconic animals.
