Hierarchy Level: Association
Type Concept: This shrubland association is only known from Petrified Forest National Park. This summary is derived from data from five relevés. This association occurs on lower slopes, midslopes, terraces, and mesas between 1740 and 1920 m (5700-6290 feet) elevation. Slope ranges between none to steep (0-22%) (average 9%). Most of the stands have basalt surface rocks, and one has sandstone surface rocks. Total vegetation cover is ranges between 15 and 24% cover (average 18%). The vegetation is characterized by an open shrub layer codominated by Purshia stansburiana and Eriogonum corymbosum, with an open to sparse herbaceous stratum (0.5-6% cover). Species diversity ranges between 20 and 24 species. Other shrubs are often present with low cover, such as Artemisia bigelovii, Atriplex canescens, Ephedra torreyana, Ephedra viridis, Brickellia oblongifolia, and Gutierrezia sarothrae. Common grasses and forbs present include Chamaesyce fendleri, Chamaesyce parryi, Cryptantha crassisepala, Phacelia crenulata, Elymus elymoides, and exotic annual grass Bromus rubens.
