The bears will be able to freely enter and exit the corrals, but some of the free-ranging beasts that ventured into the test enclosures have been none too pleased to find themselves surrounded by wire.
"Some have gotten severely pissed and destroyed the enclosures," laughs biologist Peter V. C. de Groot, of Queen's University in Kingston, Ont., who is setting up the "non-invasive" trap to help track the iconic but paradoxical creatures.
