Regeneration recruitment and survival in an Asian tropical rain forest: implications for sustainable management

A decade-long study in Sinharaja Forest Reserve, Sri Lanka, reveals critical insights for sustainable tropical forest management. Seedling mortality varies significantly across topography and species, with late-successional, shade-intolerant trees experiencing 70% mortality over eight years compared to 30% for shade-tolerant species. This challenges conventional selective logging practices that do not account for seedling recruitment periodicity or canopy manipulation. The research highlights the importance of synchronizing timber harvests with natural regeneration cycles and adapting silvicultural treatments to topographic differences in seedling composition and density, offering a science-based approach to preserve biodiversity and forest structure.
