Flight Observation Units, also referred to as Bear Observation Areas (BOAs), were delineated by the Interagency Grizzly Bear Study Team (IGBST) to facilitate systematic aerial monitoring of the grizzly bear population within the Greater Yellowstone Ecosystem. Flight units were last updated in 2014 to depict 54 distinct observation areas spanning the spatial extent of the Demographic Monitoring Area established for the Yellowstone grizzly bear population.

The Demographic Monitoring Area (DMA) is the boundary within which all demographic criteria for the Yellowstone grizzly bear population are currently monitored and evaluated. The DMA replaces the Conservation Strategy Management Area (CSMA) as the area within which total grizzly bear population size is estimated and biologically sustainable mortality thresholds are established. All grizzly bear observations and mortalities inside the DMA are counted toward population estimates and mortality thresholds; however, observations outside the monitoring area are also recorded and reported by the Interagency Grizzly Bear Study Team.

The grizzly bear distribution boundary delineates the estimated geographic extent of occupied range of the Yellowstone grizzly bear population for the period 2000-2014. The distribution boundary was generated to provide reliable estimations of grizzly bear occupancy throughout time and for use as a monitoring tool in grizzly bear management and conservation. The boundary was delineated by the Interagency Grizzly Bear Study Team (IGBST) using an interpolation method based on grizzly bear telemetry and GPS locations as well as verified observations and signs of grizzly bears inside the Greater Yellowstone ecosystem during 2000 to 2014.
