Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Gambel Oak / Cliff Fendlerbush Shrubland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This tall shrubland is known from a single plot at Canyon de Chelly National Monument in northeastern Arizona in the southern Colorado Plateau. It occurs in a west-facing canyon bottom at 1631 m (5351 feet) elevation on a gentle slope (10%) at the base of a cliff. The soil is a sandy loam and there is high cover of litter on the ground surface. The vegetation is characterized by a moderately dense (50-75% cover), tall-shrub (>10 m) canopy dominated by Quercus gambelii with Fendlera rupicola dominant in the moderate shrub layer (25-50% cover). The total vegetation cover class for this stand is 75-100%. Other shrubs (all with <1% cover) are Ericameria nauseosa, Morus alba, Opuntia polyacantha var. erinacea, and Yucca baccata. The vine Vitis arizonica is abundant. The herbaceous stratum has a high diversity of species, each having <1% cover, except for Thalictrum fendleri, which has a cover class of 1-5%. Other herbaceous species include Achillea millefolium, Arabis fendleri, Arenaria lanuginosa ssp. saxosa, Artemisia ludoviciana, Erigeron divergens, Heterotheca villosa, Hymenoxys richardsonii, Monarda fistulosa var. menthifolia, Penstemon barbatus, and Poa fendleriana. Exotic species such as Taraxacum officinale and Bromus tectorum may be present.
