Selective logging alters allometric relationships of five tropical tree species in seasonal semi-deciduous forests

In selectively logged forests, trees are more likely to expand their diameters (D) at the expense of height (H) growth, resulting in variations in H:D relationships. This study examines how selective logging affects the H:D allometric relationships of five common tree species and whether the effects...

Description
Summary:In selectively logged forests, trees are more likely to expand their diameters (D) at the expense of height (H) growth, resulting in variations in H:D relationships. This study examines how selective logging affects the H:D allometric relationships of five common tree species and whether the effects vary with functional groups (shade-intolerant or shade tolerant) in seasonal semi-deciduous forests. Individuals of five species in a 3000 m 2 (0.3 ha) plot were marked and heights and diameters recorded. Most of the species, with one exception, showed greater investment in diameter per increment of height compared to an unlogged forest, possibly because of the greater light available. This study shows the effects of selective logging on species populations as evidenced by increases in H:D ratios. Comparison of forest fragments with different degrees of human impact is important because it allows us to understand the differences in architectural characteristics caused by selective logging.
