Ulmus crassifolia (cedar elm) is found in these communities, but usually at lower density and on the deeper soils.
Surveyors found five species of trees on the study area, including four oak species and cedar elm (Ulmus crassifolia).
Range Mean Species n (Percent) (cm) (cm) Quercus marilandica 16 (5.4%) 13-30 20 Quercus fusiformis 249*(84.7%) 8-61 27 Quercus stellata 23 (7.8%) 23-71 38 Quercus buckleyi 2 (0.7%) 10-25 18 Ulmus crassifolia 4 (1.4%) 13-30 22 *no diameter available on one tree Table 2.
Other species included "cedar" = Ashe juniper (Juniperus ashei), blackjack [oak] (Quercus marilandica), "water oak" (species undetermined), "elm mott" = cedar elm (
Ulmus crassifolia), and sycamore (Platanus occidentalis).
Most of the large debris on the fallow plots were from Helianthus annuum and Abutilon incanus while the large plant debris on the brushland plots consisted of a variety of woody species, such as Ulmus crassifolia, P.
Ulmus crassifolia dominated the mature brushland edge plot overstory followed closely by C.
In the facilitated succession, three species have been added to the tree layer: hackberry,
Ulmus crassifolia (cedar elm) and colima.
Dominant trees on the study area were black oak (Quercus velutina), hickory (Carya sp.), green ash (Fraxinus pennsylvanica), sugarberry (Celtis laevigata), pecan (Carya illinoinensis), cedar elm (
Ulmus crassifolia), bois d'arc (Maclura pomifera), honey locust (Gleditsia triacanthos), post oak (Quercus stellata), red cedar (Juniperus virginiana), slippery elm (Ulmus rubra) and persimmon (Diospyros virginiana).
It has a very open, park-like under story, with an overstory typical of mature floodplain forest, dominated by native cedar elm (
Ulmus crassifolia), Mexican ash (Fraxinus berlandieriana) and sugar hackberry (Celtis laevigata), with some planted live oak (Quercus virginiana) (names from Lonard et al.
This forest contains at least 24 different tree species, the most common of which include sugar hackberry (Celtis laevigata), American hackberry (Celtis occidentalis), green ash (Fraxinus pennsylvanica), eastern cottonwood (Populus deltoides), bur oak (Quercus macrocarpa), American elm (Ulmus americana), cedar elm (Ulmus crassifolia) and slippery elm (Ulmus rubra).

Species in this category include some of the characteristic trees, shrubs, and woody vines of the eastern North American deciduous forest and particularly elements of the Coastal Plain forest, such as Ampelopsis arborea (pepper-vine), Celtis laevigata (Texas sugarberry), Cissus incisa (ivy treebine), Erythrina herbacea (coral bean), Phoradendron tomentosum (mistletoe), Quercus virginiana (live-oak), and
Ulmus crassifolia (cedar elm) (Benson, 1979; MacRoberts, 1984).
