(spring Can. Dam). July 9, 1955 NE Larimer G., G/o. With Don Harvey, Range Mgt., Colo. A & M, visited 3 colonies. At Dec. 23 colony, 10 mi. N. Waverly, noted much Atriplex cut but little Cistus. Don said range would be considered "depleted" without doubt. No evidence recent grazing there. At Dec. 10 colony, much new cover, a good forage species present, but much bare ground too. Probably would rate poor a low fair. None much Cistus cut (where little Atriplex); both it + Atriplex cut where both shrubs. Chrysophyllum present both colonies, new growth about 6" high, but now seen cut. A few Chrysopodium cut at one site. Sand dropped & Eryngopus present but rare. In slot grass plain, difference in range with use are subtle, + a great change occurs only when goes to poor. Little litter because of weird. At one site
