CEGL001284 Atriplex canescens / Calycoseris parryi Shrubland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Fourwing Saltbush / Yellow Tackstem Shrubland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This association is warm desert scrub found on nearly level alluvial plains adjacent to the Colorado River, elevation 700-800 m. The common shrubs are Atriplex canescens, Prosopis glandulosa and Suaeda moquinii. The cacti Opuntia polyacantha var. erinacea and Opuntia basilaris are common in this shrubland. Common ephemeral species include Calycoseris parryi, Chaenactis stevioides, Erodium texanum, and the Eurasian weed Bromus rubens. Near the river the Prosopis glandulosa density and size increase to form a thicket that resembles a mesquite "bosque." The soil is distinctive, a silty loam derived from the Grand Canyon series.
Diagnostic Characteristics: No Data Available
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: This association was added to the NVC based on Warren et al. (1982). Recent work in Grand Canyon National Park failed to identify any plots meeting this concept, but the association may well occur in the park or further west in Lake Mead National Recreation Area.

Environmental Description: This association is warm desert scrub found on nearly level alluvial plains adjacent to the Colorado River, elevation 700-800 m. The soil is distinctive, a silty loam derived from the Grand Canyon series.
Geographic Range: This association is only found in the eastern part of the Grand Canyon on alluvial terraces on the south side of the Colorado River between Tanner Canyon and Cardenas Creek. It may occur in unsurveyed areas outside the park such as along the Little Colorado River on the Navajo Reservation.
