An old-growth American beech community on a peninsula associated with Toledo Bend Reservoir in eastern Texas was analyzed by the plot method. Based on importance value, the community was dominated by Fagus grandifolia. Carpinus caroliniana was also prevalent. Other associated species of importance were Ostrya virginiana and Magnolia grandifolia. Results indicated that the forest was near virgin and displayed affinities with the Southern Mixed Hardwood Forest of the Coastal Plain and forests to the northeast.
