The N.W.T. Department of Environment and Climate Change (ECC) has observed a decrease in the number of bison road collisions. Between 2021 and 2025, there were 60 recorded collisions with bison, but in 2026, only one incident has been reported. Bison ecologist Terry Armstrong attributes this decline to wildfires reshaping bison behavior.
Armstrong explains that wildfires alter bison movement patterns as they seek out burnt areas with fresh vegetation. With extensive areas affected by wildfires in recent years, more bison are opting for post-fire zones instead of roadsides, leading to fewer collisions.
Wood bison, classified as a threatened species at territorial and national levels, have a population estimated at over 2,500 individuals, according to ECC data. Collisions in the past five years resulted in the deaths of at least 76 bison, with Highway 3 being a hotspot for incidents.
As the rutting season approaches from August to September, Armstrong warns of increased bison aggression towards vehicles due to mating and dominance struggles among the bulls. Reduced visibility during darker hours heightens collision risks, especially with summer driving conditions still prevalent.
Armstrong advises drivers to exercise caution, maintain distance from bison, avoid provoking them, and never attempt to interact with these formidable creatures. He emphasizes the importance of respecting bison as a vital and unique species in North America.
