The authors begin by outlining the theoretical basis of gap management, which assumes that creating canopy openings enhances tree species diversity. However, the paper emphasizes that relying solely on varying gap size often falls short of achieving diversity goals due to a multitude of interacting factors beyond light availability. These crucial factors include site history, seed dispersal, competition from other vegetation, and the impact of herbivores. The authors propose a revised, more integrated concept of gap-based silviculture that incorporates a broader range of ecological considerations and active management of understory conditions to promote structural complexity and enhance tree species diversity in these valuable forest ecosystems. -
