Researcher marks grizzly poise with a small assistance from a can of WD-40
Could roadkill stop a open kill of cattle by Alberta’s grizzly bear population?
That was a doubt behind an research of a 15-year provincial project, undertaken by Andrea Morehouse, a wildlife biologist with a University of Alberta.
The study, known as a prevent feeding program, ran from 1998 to 2013 in southwestern Alberta.
“The idea of a module was to revoke open incidents of grizzly bears murdering livestock,” Morehouse pronounced on a Calgary Eyeopener.
In an bid to change a grizzlies’ poise pattern, roadkill ungulates were collected during a winter, afterwards forsaken by a helicopter at a dozen remote sites.

The meditative behind a provincial plan was candid enough.
Morehouse pronounced it was finished “with a wish that when bears emerged from hibernation, they would feed on these piles of roadkill as opposite to going to reduce betterment areas where foliage was commencement to immature up, though cattle were calving.”
Grizzlies ‘love to massage adult opposite WD-40’
Morehouse devised a singular methodology in sequence to guard a bears in her study
“We wanted to brand how many bears were indeed regulating these sites and to do that we collected DNA samples from those bears,” she said.
At any site, there would be a raise of roadkill and they would select “two trees that were nearby that site and we sprayed those trees with WD-40 and wrapped them in spiny wire.
“For whatever reason, that we don’t know, WD-40 elicits a massage response from bears and so they would come into a sites, feed on a roadkill and afterwards massage on these synthetic massage trees that we had collected.”
The group would afterwards collect a hair samples and remove a DNA to brand how many bears were regulating a sites.
In further to a greased adult trees, a researchers worked with Fish and Wildlife officers and residents to collect hair samples from dispute sites to brand that bears were involved.Â
The series of events and a costs were also tracked.Â
The results? It turns out a grizzlies ate a roadkill. And afterwards when open calving deteriorate arrived, they ate cattle — just as many as they ever did.
As to reasons why, she can usually speculate, including some-more bears.
She combined that researchers are saying these sorts of incidents function over and over east, that would engage grizzlies with no entrance to a roadkill dropped during a sites in a southwest.
“There’s of course, changes in healthy food accessibility or healthy food contentment and continue that could have also played a purpose in this, though we didn’t guard those things directly in this project,” pronounced Morehouse.Â
After suspending the project for several years, a information has suggested no quantifiable change in a bears’ behavior. At a cost of $44,000 a year, it’s formidable to make a box to continue it, a biologist said.
“I can’t pronounce for a province, though it’s my bargain that it’s doubtful that they will be re-instituting a program,” she said.
