Name: Mimosa dysocarpa / Bouteloua curtipendula Shrubland Reference: Western Ecology Working Group of... Description: This shrubland is described from slopes of foothills, ridges and mountain canyons in southern Arizona. Plot data from Buenos Aires National Wildlife Refuge indicate an elevational range of 1140-1400 m (3750-4600 feet). Sites are somewhat steep to steep. Substrates are variable but are typically shallow rocky sandy loam to loam soils. The vegetation is characterized by a moderately dense (20-30% cover) short-shrub layer dominated by <i>Mimosa dysocarpa</i>. Tall shrubs of <i>Prosopis velutina</i> may be present but are generally too sparse to form a shrub layer (<10%). Associated shrubs and succulents include <i>Agave palmeri, Agave schottii, Calliandra eriophylla, Dasylirion wheeleri, Dodonaea viscosa, Eriogonum wrightii, Erythrina flabelliformis, Eysenhardtia orthocarpa, Mimosa aculeaticarpa var. biuncifera (= Mimosa biuncifera), Opuntia engelmannii, Opuntia spinosior</i>, and <i>Opuntia versicolor</i>. The herbaceous layer ranges from sparse to dense and typically has high species richness of forbs (>25 species). Cover is generally dominated by mixed graminoids with abundant <i>Bouteloua curtipendula</i>. Associated graminoids are <i>Eragrostis intermedia, Heteropogon contortus, Leptochloa dubia</i>, and <i>Muhlenbergia porteri</i>. Forbs with high frequency are <i>Bidens leptocephala, Boerhavia coccinea, Astrolepis sinuata (= Notholaena sinuata), Euphorbia heterophylla (= Poinsettia heterophylla), Portulaca umbraticola</i>, and <i>Sida abutifolia</i>. If present, <i>Eragrostis lehmanniana</i> has low cover (less than 25% cover and less than a third of the total perennial graminoid cover).  Accession Code: VB.CC.31791.CEGL005336 Plot-observations of this Community Concept: 0
