Reference:

Description:
This deciduous woodland association occurs on non-saline, coarse- and fine-textured Beaumont Formation strata in the lower Rio Grande Valley of Texas and Tamaulipas, Mexico. It is characterized by a scattered to open (or nearly closed) canopy emergent over a dense and diverse shrub layer with openings supporting grasses and forbs. <i>Prosopis glandulosa var. glandulosa</i> typically dominates the emergent canopy. Other canopy species include <i>Acacia greggii var. wrightii, Celtis laevigata var. laevigata, Celtis ehrenbergiana, Ebenopsis ebano, Havardia pallens</i>, and <i>Sideroxylon celastrinum</i>. The shrub layer is very dense and diverse, including <i>Acacia berlandieri, Acanthocereus tetragonus</i> (in eastern portion of lower Rio Grande delta only), <i>Adelia vaseyi, Aloysia gratissima, Amyris madrensis, Amyris texana, Bastardia viscosa, Borrichia frutescens</i> (in openings), <i>Capsicum annuum var. glabriusculum, Castela erecta ssp. texana, Celtis ehrenbergiana, Citharexylum berlandieri, Condalia hookeri, Diospyros texana, Chromolaena odorata, Xylothamia palmeri, Forestiera angustifolia, Guaiacum angustifolium, Isocoma drummondii, Jatropha dioica, Karwinskia humboldtiana, Koeberlinia spinosa, Lycium berlandieri, Malpighia glabra, Maytenus phyllanthoides, Opuntia engelmannii var. lindheimeri, Cylindropuntia leptocaulis, Phaulothamnus spinescens, Randia rhagocarpa, Yucca treculeana, Zanthoxylum fagara</i>, and <i>Ziziphus obtusifolia var. obtusifolia</i>. <i>Callisia micrantha</i> may be locally dominant in the ground cover beneath the shrubs. Herbaceous components are generally better represented in openings and may include <i>Trichloris pluriflora, Pappophorum vaginatum, Sidastrum paniculatum, Sporobolus wrightii, Billieturnera helleri</i>, and <i>Tamaulipa azurea</i>. This woodland may grade into woodlands or shrublands dominated by <i>Acacia rigidula, Acacia berlandieri</i>, or <i>Ebenopsis ebano</i> or may form a mosaic with ~<i>Bothriochloa barbinodis - Trichloris pluriflora</i> Grassland (CEGL002236)$$. This community is often impacted by the invasive grass <i>Pennisetum ciliare</i>.
