abstract
In the 1940s-1950s, large limba (Terminalia superba Engl. & Diels) plantations were established in the Democratic Republic of Congo to reduce the pressure on the natural forests. The objective of this study was to evaluate the potential of these long-rotation plantations as production forests (timber) and carbon sinks. Five different plantations, between 50 and 58 years old, were sampled. Over a sample surface of more than 73 ha, the diameter above buttresses of 2 680 trees, bole height of 265 trees and tree height of 128 trees was measured. To estimate the commercial volume, a nonlinear power law regression was used (R-2 = 0.95). A power law variance function was applied to counter heteroscedasticity of the residual plot. Estimates of commercial tree and stand volume at 50 to 58 y were 5.6 +/- 4.1 m(3) and 183.9 +/- 135.0 m(3) ha(-1). Stand volumes appear low but are explained by a large decrease in tree density. However, the mean volume increment of 3.2-3.7 m(3) ha(-1) y(-1) corresponds well with teak plantations of a similar age. For limba, aboveground biomass and carbon estimates of this study (resp. 108.4 and 54.2 Mg ha(-1)) differ significantly from those of existing aboveground biomass models (resp. 135.7-143.9 Mg ha(-1) biomass and 67.9-72.0 Mg ha(-1) C). All aboveground biomass and carbon estimates for T. superba stands were lower than for the estimates of young fast-growing plantations like Tectona grandis L. f., Eucalyptus spp. and Acacia spp. (<= 30 y).
