Members of the North Shore Black Bear Network are asking residents to stay away from a cub stranded at the foot of Grouse Mountain.

The cub got lost about a week ago after its mother was eating garbage in a residential back-yard.

"There was a neighbour's dog around or where she was eating [the garbage], the dog came around and there was a bit of a conflict between the dog and the mother bear," said Tony Webb, chair of the North Shore Black Bear Network.

"It was a defensive action by the mother bear and … so it seems as though the cub, one cub, may have been separated from the mother and the other cub."

Webb has spent the past week putting up signs asking residents in the area to keep clear of the black bear cub.

"[It's] a bit of a problem in the sense that we don't want people to feel sorry for the cub and start feeding it or something like that, [but to] just let it work its way out."

Webb is also asking residents in the area to keep their pets inside, and keep dogs from chasing the cub away.

He said chances are high that the mother and cub will find each other.

Webb estimates between 40 and 100 bears live on Vancouver's North Shore.
