| The Basis of Sustainable Forestry |  | | This movie is a simplified representation of the processes taking place in a forest to further understanding. It can not possibly show all scenarios or changes taking place.
| | | It should be noted that there are some secondary trees, (like for instance Azobé, Iroko, Ayous, Limba etc.), that favor light conditions and could live for quite a long time. Some of these trees could be harvested and used for commercial purposes.
