In Banff National Park, a well-known grizzly bear lost one of her cubs to a train incident on Sunday. According to Parks Canada spokesperson James Eastham, the young grizzly bear was hit and killed near the Eldon siding close to the Protection Mountain Campground. The bear was recognized by Parks Canada as one of two cubs accompanying the famous female Grizzly Bear 142.
The mother bear, estimated to be around 16 years old, is frequently seen in areas with human activity, making her a familiar sight to Bow Valley residents, including wildlife photographer Jason Leo Bantle. Bantle expressed sorrow over the loss, likening it to the passing of white grizzly bear Nakoda in Yoho National Park in 2024.
Bear 142, the daughter of the renowned Bear 122, also known as “The Boss,” is pivotal for the bear population in the valley. She has faced previous tragedies, such as the incident in 2020 when grizzly Split Lip killed and consumed her 2.5-year-old cub.
With approximately 65 grizzly bears in Banff National Park, these animals are considered a threatened species by the Alberta government and a species of special concern by the federal government. The Canadian Pacific Kansas City (CPKC) rail line passing through the park has resulted in numerous grizzly bear fatalities, with 19 recorded deaths since 2005.
Efforts have been made to reduce collisions between trains and wildlife in Banff. A collaborative study by Parks Canada and CPKC initiated in 2010 has led to the development of alternative wildlife travel routes, prescribed burns, forest thinning, and vegetation management programs. These initiatives aim to create safer habitats and minimize risks for animals like grizzly bears.
Experts like University of Alberta professor Colleen Cassady St. Clair highlight factors that attract bears to railway tracks, including grain spills and vegetation types. CPKC has engaged with Parks Canada to address these issues and mitigate the risks of animal strikes along the rail corridor.
Innovative measures, such as warning systems, are being explored to deter bears from approaching trains. St. Clair emphasized the importance of minimizing mortality rates of rare species like grizzly bears in protected areas to ensure their long-term survival.
This recent incident underscores the ongoing challenges faced by wildlife in Banff National Park, highlighting the need for continued conservation efforts to protect these iconic species.
