From: Characteristics of tropical human-modified forests after 20 years of natural regeneration
Forest structure of two tropical human-modified forest plots and the reference plot. The figures represent two structural indices: a height class and b diameter class. The height classes include class 1: ≤5 m; class 2: >5 and ≤10 m; class 3: >10 and ≤20 m; class 4: >20 m. Note that there was no individual in the height class 4 (>20 m) in NPI. The DBH (diameter at breast height) size class include class 1: ≥1 and <10 cm; class 2: ≥10 and < 20 cm; class 3: ≥20 cm. Abbreviations of study plots please refer to Fig. 1
