Abstract:
The Diversity of the understory is an important factor in predicting the future of forest
ecosystems. It is of great interest for the development and conservation of biodiversity. The main
objective of this study is to investigate the impact of disturbances in the undergrowth of Banco
National Park. To this end, the phytosociological characterization of the undergrowth of the old
disturbed sites and the forest reserve was carried out. The method used is that of phytosociology
under its synusial approach. 91 surveys (82 in the former silvicultural treatment sites and 9 in
forest reserve) identifies 302 species of phanerophytes distributed among 210 genera and 70
families. The dendrogram resulting from ascending hierarchical classification of readings
revealed three syntaxa, two of which consist essentially of surveys of old disturbed sites and one
of the surveys of the forest reserve. These syntaxons are characteristic of understory of preclimacic formations at different stages of development. The impact of disturbances is still felt in
the undergrowth of Banco National Park Forest in terms of floristic richness and the distribution
of species abundance in the former disturbed sites and in forest reserve. |
