Gap dynamics in logged forests, modelling and applications to the demography of shade-intermediate species.

The objectives of this thesis are to understand and model the dynamics of forest gaps based on the analysis of multi-temporal LiDAR data acquired in logged forests in French Guiana. After improving current growth and survival models for some shade-intermediate species harvested in French Guiana, the final objective of this thesis will be to integrate the forest gap model into a population dynamics simulator and to test different logging scenarios for these species. The results of this thesis will be directly applicable to the sustainable management of exploited forests in French Guiana, practiced by the ONF. Improving this management is an essential factor in maintaining the medium-term productivity of the timber industry in French Guiana.
