Quercus fusiformis - Prosopis glandulosa var. glandulosa / Malvaviscus arboreus var. drummondii Forest
Reference:
Southeastern Ecology Working Gro...
Description:
This community consists of a fine mosaic of live oak mottes and midgrass grassland openings in deep, loose sand of Pleistocene sand dunes in the South Texas Sand Sheet (mainly of Brooks and Kenedy counties). The canopy of mature mottes is composed almost entirely of Quercus fusiformis (see comments on oak taxonomy below); Prosopis glandulosa var. glandulosa is present but generally occurs at a subcanopy level in light gaps or along margins. The shrub layer is very open in mature stands and is composed of Zanthoxylum hirsutum, Condalia hookeri, Lantana urticoides (= Lantana horrida), Ziziphus obtusifolia var. obtusifolia, and a very few other species. The ground layer in deep shade is generally sparse; Malvaviscus arboreus var. drummondii is one of the few shade-tolerant herbaceous species present. Under more open mottes, grasses and forbs, more abundant in associated openings, may gain a foothold. Such openings are quite diverse and include various mid grasses, most notably Schizachyrium scoparium, Paspalum plicatulum, Eragrostis spp., and an abundance of forbs. Characteristic species include Acalypha radians, Argythamnia mercurialina var. pilosissima, Chamaecrista flexuosa var. texana, Cnidoscolus texanus, Croton argyranthemus, Dalea phleoides, Froelichia floridana, Galactia canescens, Gaura mckelveyae, Helianthemum georgianum, Monarda fruticulosa (= Monarda punctata var. fruticulosa), Phlox cuspidata, Rhynchosia americana, Stillingia sylvatica, and Thelesperma nuecense.
