CEGL004931 Acer grandidentatum - Quercus muehlenbergii - Quercus laceyi / Carex edwardsiana - Chaetopappa effusa Southern Edwards Plateau Forest

Type Concept Sentence: No Data Available


Common (Translated Scientific) Name: Bigtooth Maple - Chinquapin Oak - Lacey Oak / Edwards Plateau Sedge - Spreading Leastdaisy Southern Edwards Plateau Forest

Colloquial Name: Southern Edwards Plateau Bigtooth Maple Canyon Forest

Hierarchy Level:  Association

Type Concept: This association includes mesic canyon forests of the southern Edwards Plateau, from Kendall County west to Real County, Texas. The canopy is dominated by mixtures of Acer grandidentatum, Quercus muehlenbergii, Quercus buckleyi, Quercus laceyi, Juglans major, Prunus serotina var. eximia, Fraxinus albicans, Juniperus ashei, and (locally) Tilia americana var. caroliniana. The shrub stratum is diverse, including many species common in the surrounding landscape, as well as species more characteristic of this community, such as Lindera benzoin, Philadelphus texensis, Styrax platanifolius ssp. stellatus, Ungnadia speciosa, Frangula caroliniana, and Cornus drummondii. The herb stratum is dominated by Carex edwardsiana; other species include Aquilegia canadensis and Verbesina virginica var. virginica. Chaetopappa effusa and Tragia nigricans are characteristic and distinguish this type from the related ~Acer grandidentatum - (Quercus muehlenbergii) / Carex edwardsiana Lampasas Cutplain Forest (CEGL002319)$$. Adjacent slopes are often dominated by oak - juniper woodlands.
