Summary

The grizzly bear distribution boundary represents the estimated geographic extent of occupied range of the Yellowstone grizzly bear population for the period 1973-1979. The distribution boundary was delineated 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 1973 to1979.

Purpose

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 1973-1979. 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 1973 and 1979 as well as provide the simplicity to be updated on a frequent basis for management and conservation applications.
