Their presence in this region during winter is uncommon. River otters (Lutra canadensis), State Endangered species; are not known to be present on the review area, however, the Notch Fork of the Gunnison River is considered suitable habitat, A population exists in the Gunnison Gorge 24 miles southwest of the proposed lease tract. Lynz (Felis lvnx), State Endangered species; it is possible for their use to occur in the region, although they are not known to be present on the review area.

Grand Hesa penstemon (Penstemon mensarum), Federal category 2 species; until recently was known to occur in this area only on the north side of the North Fork of the Gunnison River in the Havksnesc drainage. During July, 1944, it's presence was documented aC eight locations on the review area b^r Dr. Robert Dorn, of Mountain West Environmental Services. From his report co the Forest Service he wrote, "Above 7800 feet it was so abundant chat it was difficult to find a relatively flat site 125 feet by 125 feet that did not have the plant. The plants were abundant along most of the roads and trails as well as in natural openings of the oak-serviceberry-chokecherry habitat which covers thousands of acres in the vicinity, most of which has difficult access. Past exploratory drilling has actually helped the plants by providing openings for them co colonize."
