Aspects de la régénération naturelle en forêt dense de Côte-d’Ivoire (Aspects of natural forest regeneration in Ivory Coast)

The author describes forest dynamics in the Ivory Coast. He discusses primarily forest regeneration as a process disturbed by perturbations that leave a gap in the canopy and notes that leading up to these disturbances, forested areas build up seed banks. The author concludes that characteristics of the disturbance determine future forest vegetation.
