Effects of thinning on the demography and functional community structure of a secondary tropical lowland rain forest.

Tropical secondary forests play a prominent role in conserving biodiversity and providing ecosystem services, but their recovery can be slow and their succession trajectory is distinct from old-growth forests. Thinning is an essential silvicultural approach to enhance the recovery rate and timber production of forests. However, the selection of trees to thin has been mainly based on size class rather than on species identity. There is little empirical or experimental evidence of species-focused thinning with the goal of altering species composition.

热带次生林（Tropical secondary forests）在保护生物多样性、提供生态系统服务方面发挥着关键作用，但其自然恢复进程往往较为缓慢，且演替轨迹与原始成熟林（old-growth forests）存在显著差异。疏伐（Thinning）是提升森林恢复速率与木材产量的核心营林措施，然而当前的疏伐选木主要依据树木径级（size class），而非物种属性（species identity）。目前鲜有以改变群落物种组成为目标的物种导向型疏伐措施的实证或试验研究证据。
