Where is Colorado Hookless Cactus (Sclerocactus glaucus)
located in the wild?
Populations of S. glaucus occur on alluvial benches and lower mesa slopes along the Green, Colorado, and Gunnison Rivers. Soils are usually coarse, gravelly river alluvium above the river flood plains. Mancos shale with volcanic cobbles and pebbles form surface material. Elevations range from 1200-2000 m. Associated vegetation is typically desert scrub dominated by Atriplex confertifolia, Hilaria jamesii, Artemesia nova, and Stipa hymenoides. Other important species include Echinocereus triglochidiatus var. melanacanthus, Pediocacus simpsonii, Opuntia polycantha, Krascheninnikovia lanata, Yucca harrimaniae, Gutierrezia sarothrae, Crysothamnus viscidiflorus, Sporobolus cryptandrus, and Elymus salinus.
