Montana Fish, Wildlife & Parks, in cooperation with other state and federal agencies, initiated a program in 2004 to monitor the population trend of grizzly bears in NCDE.

The purpose of this long-term program is to monitor the vital population parameters of grizzly bears by assessing the survival and reproductive rates, and trend. This will be accomplished by radio-monitoring female grizzly bears.

This research works allows FWP biologist to monitor the survival and reproductive rates of female grizzly bears to determine population trend, monitor distribution of bears within and adjacent to the federal recovery zone, and collect information on other pertinent aspects of grizzly bear ecology.

The work of this program is summarized in the annual reports listed below.
