ActasSummary: Proper design and management of plantations can increase biomass accumulation rates, making them more effective carbon sinks. We compared biomass production and carbon sequestration by three 6-year-old native tree plantations in pure and mixed-species plots in the Atlantic humid lowlands of Costa Rica. In Plantation 1, Vochysia guatemalensis had the highest levels of carbon accumulation (40.2 Mg C ha exponente -1) followed by Jacaranda copaia (40.1 Mg C ha exponente -1) and the four-species mixed stands (39.0 Mg C ha exponente -1). In Plantation 2, the mixed plantations and Dipteryx panamensis (19.9 and 19.57 Mg C ha exponente -1) had the highest carbon accumulation. In Plantation 3, Hyeronima alchorneoides had the highest values (15.8 Mg C ha exponente -1) followed by V. ferruginea (13.4 Mg C ha exponente -1) and the four-species mixture (11.4 Mg C ha exponente -1). The results suggest that several native tree species in the region have a potential for high carbon accumulation and that changing plantation design can increase the biomass accumulation rates of tree plantations.
