The N.W.T. Department of Environment and Climate Change (ECC) has noted a decrease in the number of bison collisions on roads in the region. Between 2021 and 2025, there were 60 recorded collisions with bison. However, in 2026, only one such incident has been reported.
Bison ecologist Terry Armstrong attributes this decline to wildfires in the area. He explains that fires prompt bison to alter their movement patterns, with the animals often migrating to recently burned areas to take advantage of fresh vegetation growth. This behavior shift has led to fewer bison sightings near roads, reducing the chances of collisions.
Wood bison, classified as a threatened species at both territorial and national levels, have seen a positive impact from this trend. The estimated bison population in the N.W.T. is currently several thousand, with ECC estimating it to be slightly over 2,500 individuals.
ECC spokesperson Toyeke Adedipe revealed that between 2021 and 2025, at least 76 bison deaths resulted from collisions, with some incidents involving multiple animals. Highway 3 witnessed the highest number of collisions, accounting for 45 incidents and 56 bison fatalities.
Armstrong warns that the rutting season, typically from August to September, poses a higher risk of aggressive bison encounters on roads. During this period, bulls engage in dominance battles and mating pursuits, potentially leading to collisions with vehicles.
As daylight diminishes and visibility decreases, particularly during dawn and dusk, the likelihood of collisions rises. Armstrong advises drivers to proceed cautiously, maintain distance from bison, and refrain from actions that could startle them, such as honking. Above all, he emphasizes the importance of staying inside vehicles and avoiding any attempts to interact with the bison.
Describing bison as the largest land mammal in North America and resilient survivors with a long history, Armstrong urges respect for these unique creatures and emphasizes the need to protect their dwindling population.
