CEGL004594 Juglans microcarpa / Sorghastrum nutans Flooded Scrub Woodland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Little Walnut / Indiangrass Flooded Scrub Woodland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This community occurs in Texas in intermittently to temporarily flooded streambeds and stream margins with headwaters in montane areas. Even when the streambed is dry, it is usually subirrigated; following rains, the streambed can be shallowly inundated for several weeks at a time. Woody vegetation is extremely variable in height and density, varying from shrubby growth to well-developed trees, and from an open canopy to widely scattered individuals. Juglans microcarpa is the most abundant and most characteristic woody species; others include Fraxinus velutina, Baccharis salicifolia, Fallugia paradoxa, and Ostrya knowltonii. The streambed and margins are dominated by Sorghastrum nutans, with other herbs including Schizachyrium scoparium var. scoparium, Andropogon gerardii, Echinochloa muricata var. microstachya, Bothriochloa barbinodis, Leptochloa dubia, and other scattered herbs, many typical of adjoining upland areas.
