Table 1
Structure and productivity of the secondary forest (SF) at different ages after clear-cutting MSF (>40 years) and a primary forest (PF) in Buenaventura, Colombia. Age: years after clear-cutting. DBH: diameter breast height. HT: height total. D: diameter. BA: basal area. Vol: volume. AGB: above-ground biomass.
