Observation Narrative
Plot captures a small area on a large flat plain with fairly mature hydric oaks. Largest trees are 70-75 cm DBH; most are 40-55 cm DBH. Leaf litter dominates the ground cover and herbs are sparse. This site appears to be saturated by seasonally perched groundwater and perhaps temporarily and shallowly ponded in local depressions during wet periods.
