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

Table 2

Mean, total, and Jackknife estimated species richness in 192 seed bank samples collected from six revegetating clearcut (CC; ∼7 years) and six second-growth (SG; ∼125 years) forest stands at WWRS. Double asterisk (**) indicates significant difference in CC and SG richness (𝑃<.01). Letters indicate significant difference among CC/SG topographic aspect classes (𝑃<.05).
