Resumen
Descripción
This study explores the present forest management systems in place in the Brazilian Amazon through the analysis of the impacts of logging on the genetic diversity and the ecology of Hymenaea courbaril. This study was carried out in the Tapajós National Forest, in a 500 ha Intensive Permanent Plot area as part of the Dendrogene Project (EMBRAPA/DFID). Its main objective is to evaluate the effects of Reduced Impact Logging (RIL) on the species’ genetic variability and ecological processes and to predict the likely impacts in the short- and long-term. The specific objectives are to determine impacts of harvesting on forest structure and the species’ reproductive population and spatial pattern, to determine Hymenaea courbaril’s genetic diversity, spatial genetic structure, pollen flow and mating system, and assess the impact of logging on these processes, and finally to infer the impact of logging on Hymenaea courbaril’s sustainability in the long-term using the modelling software Eco-gene.
