This study assesses the growth potential of 5 native late-successional species of Southwestern Sri Lanka under Pinus caribaea, grown in plantations, to inform appropriate species choice and placement in enrichment plantings. The authors evaluated growth over 2 years, measuring eight, basal stem diameter, number of leaves, and mortality. They destructively sampled some individuals to also measure leaf area and dry mass of roots, stems and leaves. The study successfully demonstrates that native late-successional species can be grown under P. caribaea, though seedlings must have DPPF levels 4-5 times greater than those present beneath a closed Pinus canopy. D. zeylanicus may be best suited for sites prone to desiccation, and S. disticha and S. megistophylla best for planting under intact canopy.
