CEGL003874 Acacia rigidula Shrubland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Blackbrush Acacia Shrubland
Colloquial Name: Chaparro-Prieto Shrubland
Hierarchy Level: Association
Type Concept: This association is broadly defined to include shrublands occurring over a range of shallow soils (gravels, sands, heavy clay), in the uplands of the South Texas Plains and the coastal bend area of the Gulf Coast Prairies and Marshes of Texas. Associated shrubs depend on soils, slope, and cultural influences but can include Acacia berlandieri, Prosopis glandulosa, Prosopis reptans, Celtis ehrenbergiana, Ziziphus obtusifolia var. obtusifolia, Diospyros texana, Mahonia trifoliolata, Condalia hookeri, Zanthoxylum fagara, and Acacia spp. Herbaceous vegetation within mottes is usually sparse but may include Leersia monandra and Setaria leucopila. These shrublands often occur as mottes that are intermixed with other shrublands or woodlands dominated by Acacia berlandieri, Celtis ehrenbergiana, and Prosopis glandulosa var. glandulosa and with coastal grasslands characterized by Bouteloua dactyloides, Bouteloua rigidiseta, Aristida purpurea, Bothriochloa barbinodis, Sporobolus compositus var. compositus, Bothriochloa longipaniculata, Bothriochloa laguroides, Trichloris pluriflora, Schizachyrium scoparium, and Nassella leucotricha.
