4.2. Aboveground biomass and C content
As expected the two introduced species had the highest aboveground biomass (and hence carbon sequestration) due to its high adaptability and growth on acid unfertile soils (Ecoregion 2). But as discussed before these differences could be reduced as site fertility and soil moisture improve. The information about C content and the set of equations to estimate aboveground biomass by tree compartments and whole tree, for each of the species or group of species, are significant contributions for further studies of nutrient cycling, site nutrient management and carbon sequestration. Caution must be taken when using these equations; their application should
