The recent rise in bear sightings across Alberta’s mountain parks has prompted wildlife experts to issue urgent warnings for those venturing into bear territory. As spring awakens the bears from their winter slumber, they are actively searching for food, leading to increased encounters with hikers and outdoor enthusiasts. Nick de Ruyter, the director of WildSmart at the Biosphere of the Bow Valley, emphasised the importance of awareness during this critical time.
Increased Bear Activity in Spring
With the arrival of spring, bears emerge from hibernation after months of inactivity, hungry and eager to replenish their energy. De Ruyter explained, “At springtime, all the bears just got out of their dens after five to six months, and they’re looking for food.” The melting snow at higher elevations drives bears down to the valleys, where they can find an abundance of early-season vegetation, including tender grass and dandelions—both attractive food sources for these animals.
As more people flock to the mountains for recreation, the likelihood of encounters with bears naturally escalates. Recent reports from Banff National Park revealed a bear warning issued for the Boom, Arnica, and Twin Lakes trails, as well as the Twin Lake campground, due to a cinnamon-coloured black bear that displayed concerning behaviour by closely following a hiker.
Trail Closures and Warnings
In Kananaskis Country, a series of closures and warnings have been enacted this week. The Terrace Trail and Kovach Ski Trails in Spray Lakes Provincial Park have been shut down, while warnings extend to the Heart Creek Trail and Trans Canada Trail, where multiple sightings of black bears, including those with cubs, have been reported. On Monday, a warning was specifically issued for the Heart Creek area, highlighting the urgency of the situation.

The presence of bears seeking food along popular trails raises significant safety concerns. De Ruyter noted that the bears are particularly drawn to areas frequented by people, making it essential for hikers to stay vigilant. “The easiest food they’re keying on is green grass and dandelions, often found along roads and highways, trails, campgrounds, parks, and backyards,” he explained.
Safety Tips for Outdoor Enthusiasts
For those planning to explore the backcountry, de Ruyter provided several important safety tips. First and foremost, hikers should check for any trail warnings and closures before setting out. The purchase and proper use of bear spray is crucial; it should always be carried on one’s person, never in a backpack.
De Ruyter also advised hikers to make noise while on the trails. “When you get to the trail, making noise is key, and ideally, you should go in a group,” he said. He suggested the use of a human voice to alert bears to human presence, stating, “‘Hey-oh!’ is much better than bear bells, which aren’t loud enough.” Keeping pets leashed and giving wildlife ample space are equally important strategies for minimising encounters.
“If you don’t get close to a bear, you’re not going to have a problem with a bear,” de Ruyter affirmed, underscoring the importance of respecting wildlife boundaries.
Seasonal Bear Movements
As summer approaches, bear behaviour will continue to evolve. De Ruyter explained that bears will gradually move to higher elevations but will return to the valleys during berry season in late summer. This seasonal shift means that outdoor enthusiasts should remain cautious throughout the warmer months, as bears will be active in their search for food.

Why it Matters
The surge in bear sightings serves as a crucial reminder of the delicate balance between human activity and wildlife conservation in Alberta’s natural ecosystems. As more people engage with the great outdoors, it is imperative to prioritise safety and respect for wildlife to ensure both human and animal well-being. Understanding bear behaviour and taking necessary precautions can help protect these magnificent creatures and preserve the integrity of their habitats for future generations.
