Silvicultural interventions and their effects on forest dynamics and production in some rain forests of Côte d'Ivoire
The reaction of the tropical rain forest to différent silvicultural operations - logging and thinning - was investigated in three reserved forests of Côte d'Ivoire (one evergreen, one semi-deciduous, one transitional between the two). A similar 400 ha experimental area was laid out in each forest type, eachdivided into 25 plots of 16 ha. Three sets of measurements, made on more than 48 000 individual trees over a span of 4 years, provided data on diameter growth and annual increment of more than 50 merchantable species, thus yielding information formerly unavailable about the requirements and behaviour of these species. Taking into account growth, mortality, and regeneration of the entire stand, silvicultural operations frequently result in a doubling of annual production, and also favour the recruitment of the most desirable species. As a result of these findings, a larger scale pilot programme in forest management is being carried out in a 10 000 ha block of evergreen tropical forest at Yapo.
