A tranquilized grizzly bear in a culvert trap. Radio collars are invaluable tools which allow bear researchers and managers to gather survival and reproductive data on individual bears. Once enough data, approximately bear years, is accumulated it becomes possible to mathematically estimate trends in the grizzly population. A bear year is gathered through monitoring a single bear over the course of one year. Thus, a sample of collared bears tracked for years would yield bear years of data.

A bear year is gathered through monitoring a single bear over the course of one year. Thus, a sample of collared bears tracked for years would yield bear years of data. Managers of the Northern Continental Divide Ecosystem (of which Glacier National Park is a part) are striving to keep bears (primarily females with cubs) radio collared with state-of-the-art GPS/ARGOS collars. These collars locate themselves through the Global Positioning Satellite (GPS) system and then transmit their location to researchers through the ARGOS satellite system. This provides bear researchers and managers with invaluable data, including near real-time location information about individual grizzly in a culvert trap (Northern Divide Grizzly Bear.
