CEGL007793 Vachellia farnesiana - Celtis laevigata - Celtis ehrenbergiana Ruderal Scrub
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Sweet Acacia - Sugarberry - Spiny Hackberry Ruderal Scrub
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This woodland (to closed-canopy forest) occurs on disturbed silty soils on the South Texas Plains. The canopy coverage is variable; in addition to Vachellia farnesiana, Celtis ehrenbergiana, and Celtis laevigata, other common canopy species include Parkinsonia aculeata and Prosopis glandulosa var. glandulosa may also be common. Depending on management, the shrub layer may be open or dense, with Baccharis neglecta in heavily disturbed sites and Zanthoxylum fagara, Ziziphus obtusifolia, and other spiny or unpalatable shrubs in less disturbed areas. Due to heavy use by cattle, the ground layer vegetation is generally weedy, typically dominated by species such as Bromus arvensis, Nassella leucotricha, and Galium aparine in spring, and Dichanthium spp., Ambrosia trifida, Clematis drummondii, Funastrum cynanchoides, Ratibida columnifera, and Helianthus annuus later in the season.

Classification Comments: Kartesz (1999) uses Acacia farnesiana for Acacia smallii (which is accepted by Isely), and which is now treated as Vachellia farnesiana (USDA Plants 2017). Some occurrences of this community could be classified as a shrubland (<5 m in height). This is an upland community. Similar vegetation occurring in floodplains and other poorly drained areas is classified as ~Vachellia farnesiana - (Prosopis glandulosa) Riparian Woodland (CEGL002131)$$.

Floristics: The canopy coverage is variable; in addition to Vachellia farnesiana (= Acacia farnesiana), Celtis ehrenbergiana (= Celtis pallida), and Celtis laevigata, other common canopy species include Parkinsonia aculeata and Prosopis glandulosa var. glandulosa may also be common. Depending on management, the shrub layer may be open or dense, with Baccharis neglecta in heavily disturbed sites and Zanthoxylum fagara, Ziziphus obtusifolia, and other spiny or unpalatable shrubs in less disturbed areas. Due to heavy use by cattle, the ground layer vegetation is generally weedy, typically dominated by species such as Bromus arvensis (= Bromus japonicus), Nassella leucotricha (= Stipa leucotricha), and Galium aparine in spring, and Dichanthium spp., Ambrosia trifida, Clematis drummondii, Funastrum cynanchoides (= Sarcostemma cynanchoides), Ratibida columnifera (= Ratibida columnaris), and Helianthus annuus later in the season.
