Improving productivity and enhancing other ecosystem services are the main reasons for this conversion.While mixing effects in temperate forests and plantations are well supported by empirical data, such information is scarce fortropical forest plantations. We analyzed the quantitative aboveground tree biomass—structure—tree diversity relationshipin a tropical mixed-forest plantation in Northern Vietnam, hypothesizing that aboveground tree biomass would be increasedwith greater structural and species diversity. The study site was in a mixed abandoned plantation of Acacia mangium andAcacia auriculiformis in Northern Vietnam. A one-hectare permanent plot was installed in which all trees were identi-fied individually by species, measured (diameter and height), and georeferenced. The descriptive analysis found that thestudy area contains 110.66 tons/ha of biomass in the aboveground tree compartments. The structural and species diversityanalysis indicated high richness and evenness. A set of models was fitted and ranked to determine the relationship betweenaboveground tree biomass and structural and specific diversity. The results indicate that the species diversity and evenness,described by the Shannon index, and height differentiation indexes were negatively significant for both species while basalarea was only positively significant for Acacia mangium. According to the model sensitivity analysis, aboveground treebiomass—and therefore carbon concentration—decreases as species diversity increases PB Springer SN 1612-4669 YR 2025 FD 2025 LK https://uvadoc.uva.es/handle/10324/75940 UL https://uvadoc.uva.es/handle/10324/75940 LA eng NO European Journal of Forest Research, 2025.
