When looking for a place to set up a capture location, biologists look for existing bear sign such as scratches on trees and bear scat.  Sometimes traps are set in areas that have no obvious bear sign to determine if indeed bears are present.

Scientists sample for alpine insects in streams like this near Blackfoot Glacier in Glacier National Park. Alpine streams environments in the northern Rocky Mountains are especially vulnerable to climate change due to rapid warming resulting in loss of glaciers and snowpack.
