This article assesses the effect of different logging levels on loss of above-ground biomass and the contribution of different ecological groups of species in the long-term recovery of C stocks. A randomized complete blocks design was established in 1987 with three felling treatments: diameter above 20 cm, 40 cm and 60 cm. All the trees and palms bigger than 10 cm dbh were measured. The average stock in old growth forests was 84.3 t C/ha. Low- and medium-impact treatments led to C reductions in 10% and 44%, respectively; for low impact, a significant increase was detected after the 25-year measurements, which could be related to a possible CO2 fertilization effect. For high impact, 79% of C was lost, but the original level recovered after 20 years. The ecological succession process, subsequent to logging, is an efficient mechanism to restore C stocks.
