Fig. 1. Evolution of the number of exploitable trees after logging for two important commercial species (Entandrophragma cylindricum and Triplochiton scleroxylon) in the Central African Republic (CAR). Predictions were made using a stochastic matrix model calibrated with data from the M'Baïki experimental site in the CAR (methods are described in Gourlet-Fleury et al. 2004, 2005), and were compared to long-term observations from this site.
