Tree abundance and diversity metrics across 32 research plots used to evaluate Beech bark disease regeneration treatments in 2019 (pre-harvest), 2020 (1-year post-harvest), and 2024 (5-years post-harvest). American beech was grouped into five size classes, and tree counts were also categorized by management relevance (target, acceptable, nonacceptable). Values in parentheses represent the 95% confidence interval around each estimated marginal means (based on mixed-effects models).

本数据集涵盖32块研究样地的树木丰度与多样性指标，用于评估2019年（采伐前）、2020年（采伐后1年）及2024年（采伐后5年）的山毛榉树皮病（Beech bark disease）更新处理效果。研究将美洲山毛榉（American beech）划分为5个径级，同时依据管理相关性将树木数量划分为目标类、可接受类与不可接受类。括号内数值为各估计边际均值的95%置信区间，其计算基于混合效应模型（mixed-effects models）。
