What does this research mean for the field?

Forest management interventions often increase short-term local understory species richness but lead to long-term compositional homogenization and declines in forest specialists, making low-to-moderate-intensity systems with structural retention most effective for biodiversity conservation. Novelty: ClaimNovelty.SYNTHESIS. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

To synthesize global research trends, environmental drivers, and community responses of understory vegetation to forest management interventions to inform biodiversity conservation.
Conducted a bibliometric evaluation of global literature published between 1986 and 2025 (N=726 publications) across Environmental Sciences and forestry domains.
Performed a qualitative synthesis of empirical studies assessing understory responses to canopy alterations, including thinning, harvesting, gap creation, and prescribed fire.
Interventions like canopy thinning, timber harvesting, and prescribed fire consistently increase local (α) species richness in the short term by favoring light-demanding, early-seral species.
Disturbances frequently reduce bryophytes and specialized forest species, resulting in decreased spatial heterogeneity (β-diversity) and regional community homogenization.
Retention of structural legacies such as large trees and deadwood, combined with low-to-moderate-intensity harvesting, most effectively preserves specialist biodiversity.

Implication

Literature review reveals increased local richness alongside community homogenization in managed forest understories, indicating that low-intensity disturbance best conserves specialist taxa.
