Fig. 3. Current and historical Gunnison sage-grouse range. See next page for details on numbers found on map.
Fig. 4. Locations of current Gunnison sage-grouse populations. The discontinuity in occupied habitat at the state line in the Dove
Creek - Monticello area is not entirely a mapping artifact; where there is occupied habitat on the Colorado side there is an abrupt
change to cropland on the Utah side of the border. The abrupt transition at the state border in the Piñon Mesa area may be due to
differing mapping efforts between the states and is addressed in the “Habitat Monitoring” rangewide strategy (see Objective 1,
Strategy 3, pg. 221).
