The grizzly bear distribution boundary for the Greater Yellowstone Ecosystem was constructed by the Interagency Grizzly Bear Study Team to provide an accurate estimate of occupied range of grizzly bears for the period 2006-2020. The method for delineating distribution was based on a kriged interpolation technique and was designed to use verified grizzly bear observation and location data from all sources between 2006 and 2020 and provide the simplicity to be updated on a frequent basis for management and conservation applications.
