Name: Rhus trilobata Rocky Mountain Shrub Herbaceous Vegetation
Reference: Western Ecology Working Group of...
Description: This association occurs in the montane and subalpine zones of the southern Rocky Mountains. Stands occur in patches on rock ledges, scree and other steep slopes (50-100%). Substrates are shallow, rocky, rapidly drained, coarse-textured soils derived from various parent materials such as granite. Ground surfaces have moderate to high cover of rock. The vegetation is characterized by an open to moderately dense short-shrub layer dominated by <i>Rhus trilobata</i> and a moderately dense to dense herbaceous layer dominated by montane perennial graminoids. Other shrubs and dwarf-shrubs occurring in this stratum include <i>Chrysothamnus viscidiflorus, Purshia tridentata, Ribes cereum</i>, and <i>Artemisia frigida</i>. <i>Muhlenbergia montana</i> is generally present. Other perennial graminoid species may include <i>Bouteloua gracilis, Bromus inermis var. pumpellianus (= Bromus pumpellianus), Carex geophila, Elymus elymoides, Elymus trachycaulus</i>, and <i>Festuca arizonica</i>. <i>Bromus tectorum</i> cover is high in disturbed stands. Forb species occur at low percent cover and include <i>Artemisia ludoviciana, Chenopodium berlandieri, Eriogonum umbellatum var. umbellatum, Festuca arizonica, Helianthus pumilus, Heterotheca villosa, Mertensia lanceolata, Opuntia polyacantha</i>, and <i>Potentilla fissa</i>. <i>Rubus deliciosus, Juniperus scopulorum</i>, and <i>Pinus ponderosa var. scopulorum</i> also occur in the area of this association.
