Payment for environmental services in Costa Rica: carbon sequestration estimations of native tree plantations.
The aboveground biomass and carbon sequestration in small and medium-sized native tree plantations in the Atlantic (Sarapiqui) and Northern lowlands (San Carlos) of Costa rica were estimated using allometric equations. Seven native tree species (Vochysia ferruginea, V. guatemalensis, Hyeronima alchorneoides, Calophyllum brasiliense, Terminalia amazonia, Virola koschnyii and Dipteryx panamensis) were analysed in this study. The sarapiqui plantations presented higher carbon values by species than the San Carlos plantations. In San Carlos, V. guatemalensis and T. amazonia had the highest total carbon sequestration per tree. The estimates of carbon sequestration per hectare indicated that D. panamensis and V. guatemalensis. In Sarapiqui, the species with the highest total carbon sequestration per tree were T. amazonica and T. amazonica and H. achorneoides. However, no significant difference were found among the seven species. The percentage carbon sequestration in the different tree components (stem, branches, and foliage) was similar in both locations.
