CEGL002781 Chrysothamnus viscidiflorus - Ericameria parryi Shrub Grassland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Yellow Rabbitbrush - Parry''s Rabbitbrush Shrub Grassland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This is a dry, sparse herbaceous shrubland thought to be primarily the result of disturbance by ungulate overgrazing. At present it is known from central Colorado and southern Utah. The following description is from Colorado stands only. This shrubland occurs at an elevation of approximately 2535-2580 m (8325-8462 feet). It occupies decomposing granite gravels with fine silt and clay soil particles interspersed. Stand exposure ranges from northeast to southeast (60-165°), and the slopes are moderately steep, from 5-11%. The sites are considered well-drained to rapidly drained. Similar sites elsewhere would support a Festuca arizonica - Muhlenbergia filiculmis grassland. The dominant dwarf-shrubs, e.g., Chrysothamnus viscidiflorus and Ericameria parryi, Artemisia frigida, and Gutierrezia sarothrae, typically provide from 20-35% foliar cover. Grass species common in these stands include Bouteloua gracilis, Muhlenbergia filiculmis, Festuca arizonica, Elymus elymoides, and Koeleria macrantha, and they provide from 15-25% foliar cover. Foliar cover by forbs was less than 5% for all stands sampled and typically was in the range of 2-4%. The more common forbs observed included Hymenoxys richardsonii, Geranium caespitosum, and Besseya plantaginea.
