CEGL005009 Dalea formosa - Mimosa borealis Dwarf-shrubland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Featherplume - Fragrant Mimosa Dwarf-shrubland
Colloquial Name: Featherplume - Mimosa Dwarf-shrubland
Hierarchy Level: Association
Type Concept: This association has been identified in the northern panhandle of Texas but is likely found in other areas in similar habitats. The association occurs as narrow bands along the tops of escarpments and narrow ridges where bedrock is at or very near the surface. Bedrock outcrops and rocks are abundant. Soil is shallow. It is dominated by dwarf-shrubs with variable cover of herbaceous plants. The dwarf-shrubs typically have moderate cover. Herbaceous cover can be sparse to moderate. The dominant shrubs are Dalea formosa and Mimosa borealis, with Gutierrezia sarothrae often present and sometimes abundant in wet years. A variety of herbaceous species may be present, but Aristida purpurea and Bouteloua curtipendula are among the most common.

Floristics: This community is a dwarf-shrubland with Dalea formosa being the dominant shrub. Mimosa borealis is secondary in abundance. Overall cover is somewhat sparse. Other shrubs that occur in token amounts include Yucca glauca and Krascheninnikovia lanata. Cacti species present in small amounts are Opuntia phaeacantha and Echinocereus reichenbachii. Common forbs are Gutierrezia sarothrae, Tetraneuris scaposa, and Eriogonum longifolium. Aristida purpurea, Tridens muticus, and Bouteloua curtipendula are the most prevalent grass species. The total biomass produced is low. Litter production is very low. Occasionally cryptogamic crusts are visible. Occasional lichens show up on rocks.
Dynamics: No Data Available
Environmental Description: The community occurs on very shallow upland soils with high rock content. Bedrock is exposed on approximately 15% of the land surface. Soils are never more than 10 cm (4 inches) in depth. Infiltration is limited due to soil depth, and runoff is moderately rapid. Topography varies from gently sloping to moderately steep. The community is limited to narrow bands around the edge of escarpments and on very shallow-soiled ridges and hilltops.
Geographic Range: This association is known from the northern panhandle of Texas but is likely found in other areas in similar habitats.
