Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Honey Mesquite - Spiny Hackberry / Prickly-pear species - Texas Desert Goldenrod Scrub
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This community typically occurs on heavy clay soils over the Pleistocene Beaumont Formation, on inland sites near the coast of southern Texas. Prosopis glandulosa var. glandulosa 3-6 m in height provide 50-75% cover, sometimes mixed with Celtis ehrenbergiana and relatively few other tall woody species; Vachellia farnesiana is present in lower areas. Opuntia engelmannii var. lindheimeri, Cylindropuntia leptocaulis, and Xylothamia palmeri are typically common in the shrub layer, along with Ziziphus obtusifolia var. obtusifolia, Lantana urticoides, Prosopis reptans, and other unpalatable species; shrub density is often highest under taller mesquite. Ground layer vegetation varies considerably with season and livestock stocking; important species include Nassella leucotricha, Bouteloua dactyloides, Bothriochloa longipaniculata, Sporobolus compositus, Panicum hallii, Tridens texanus, Aristida spp., Setaria spp., Malvastrum spp., Ratibida columnifera, Ambrosia psilostachya, Abutilon spp., and Allowissadula lozanii. Dichanthium annulatum is a common non-native invader.

Classification Comments: This community shares some vegetational and environmental characteristics with ~Prosopis glandulosa var. glandulosa / (Celtis ehrenbergiana, Phaulothamnus spinescens, Ziziphus obtusifolia var. obtusifolia) Woodland (CEGL002132)$$ that occurs on non-saline, coarse- and fine-textured Beaumont Formation strata in the southern part of the Gulf Coast Prairies and Marshes Ecoregion. The later community is differentiated by its diverse shrub layer of subtropical species that do not range north of the lower Rio Grande Valley of Texas. The successional history of this community is unclear. It is a degraded version of a natural community, but it is unclear what that natural community was and whether any of it remains in a natural condition today. More information is needed to determine if it should be merged with ~Prosopis glandulosa var. glandulosa / Celtis ehrenbergiana - Opuntia spp. Ruderal Scrub (CEGL007756)$$.
