Just a point about relocation. It has been found both in the Banff and Jasper Park areas that relocation often doesn't work, and is very costly. Bears that are tranquilized have been taken 20 , 30 , and 40 miles away and collared and released. The distance often determines just how long it takes for the animal to return to the townsite. This process is not repeated over and over , but instead after returning two to three times the animal is euthanized to avoid any problem encounters with humans.
