A recent federal assessment indicates that badgers, prevalent on the Prairies, are facing similar threats to endangered populations in Ontario and British Columbia. The American badger, the sole species of badger in North America, is categorized into three populations by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC). The “Kootenay, Prairies, and Rainy River” population, covering the Prairie provinces, parts of southeastern British Columbia, and northwestern Ontario, was designated as “special concern” in December. The other two populations in southwestern Ontario and the B.C. Interior are classified as endangered, with estimations of fewer than 250 adult badgers in each region.
Chris Johnson, a COSEWIC terrestrial mammals subcommittee member from the University of Northern British Columbia, highlighted the challenges in estimating badger numbers due to their elusive nature. He emphasized the various risks and threats badgers face in Canada, including habitat loss, vehicle collisions, and intentional killings by landowners.
The Wildlife Watch Program in Alberta reported 112 badger roadkill carcasses in 2024, emphasizing the common occurrence of vehicle collisions as a cause of badger fatalities. Calgary wildlife biologist Chris Fisher noted that badgers are often found near roads due to the ease of digging burrows in sloped ditches, where Richardson’s ground squirrels, a primary prey for badgers, are plentiful.
Habitat loss is a significant concern for endangered badger populations in southwestern Ontario and the B.C. Interior, as urban expansion encroaches on their natural habitat. This loss of grassland ecosystems, considered among the most endangered globally, poses a threat to various species, including the American badger. These animals play a crucial role as “ecosystem engineers,” creating burrows that benefit numerous other species.
Despite their ecological importance, badgers face persecution from humans, who often shoot them due to perceived threats to livestock and property damage. While badgers are classified as sensitive species in Alberta and not currently at risk of extinction, they require special attention to prevent future endangerment. Measures such as protecting active badger dens from construction activities can help safeguard these vulnerable populations.
