Seed Bank Variation under Contrasting Site Quality Conditions in Mixed Oak Forests of Southeastern Ohio, USA

Table 1

Mean, total, and Jackknife estimated species richness of aboveground vegetation in 192 quadrats established in six revegetating clearcut (CC; ∼7 years) and six second-growth (SG; ∼125 years) forest stands at WWRS. Asterisk (*) indicates significant difference in CC and SG richness (𝑃<.05). Letters indicate significant difference among CC/SG topographic aspect classes (𝑃<.05).
