Grizzly bear ‘highway’ found on West Coast
First Nations researchers find centuries-old paw prints that show bears are very predictable in both the times of day they’re active and the routes they take

First Nations researchers have discovered what they believe is a grizzly-bear highway of sorts: centuries-old paw prints worn deep into the mossy floor of the Pacific Coast rain forest.
“I suspect that these grizzly bear paths have been here as long as grizzly bears have been here,” said William Housty, director of Coastwatch, a scientific initiative led by the Heiltsuk First Nation.
The Heiltsuk people have been in the area for 9,000 years and Housty believes the grizzly bear roadways along the waterways go back generations.
“Grizzly bears are very similar to humans in the way that they nurture their young, and raise them to know the territory around them,” Housty said in an email from the woods.
Heiltsuk people have shared and maintained the same roadways over generations, creating a lasting connection between the Heiltsuk and grizzly bears, Housty said.
When the logging stopped, the bear populations rebounded, he said.
Grizzly bears can weigh 363 kilograms (800 lbs.) and stand 2.4 meters (eight feet) on their hind legs, but Housty insists the grizzly bear study isn’t dangerous, as long as it’s done with respect and good sense.
“We do spend a lot of time in the wild, on foot with these bears, and have never once had a negative encounter with any of them,” Housty says.
“We have the greatest respect for the bears, and always make sure to let them know when we are in the area, and there seems to be a mutual respect from them as well. Never have we ever carried a fire arm when doing this study, however we did carry bear spray. But overall, I do not consider the study to be dangerous.”
He’s one of three technicians working on the study, but there are also youth and family camp programs operating in the same study area, meaning there can be from 40 to 60 people in the Koeye watershed at one time during the summer months.
He said his group are currently working with the neighbouring Kitasoo, Nuxalk and Wuikinuxv First Nations, as well as with academic institutions such as the University of Victoria and Raincoast Conservation Society to take a more regional approach to this study.
As they got to know the grizzly bears, Housty said it became clear they have routines, much like humans.
“There are certain areas where grizzlies go to feed on salmon and berries, and if you spend enough time, you can pinpoint an exact time when they go to feed at the same time every day — usually at dusk and dawn,” Housty said. “They also do the same when it comes to berries. They work in cycles, and move to and fro within the watershed chasing berries and trickles of salmon that are coming in. It is very easy to predict when bears will be out and about.”
