| Résumé : | This work is the first analysis of the totality of the plant biodiversity inventories made in the Odzala National Park. It deals especially with habitat diversity and phytogeographical groups based ou the correctly determined species of the curent flora. The global taxonomic list consists of 1141 species belonging to 125 families. Forest habitat is the most diversified with 806 species reaching 71% of the total, of wich 537 belong to the "forêt de terre ferme". Grassy habitat includes 335 species reaching 29% of the total, 143 species belonging to the savanna. At the phytogeographical groups level, the basic Guineo-Congolian element is the most important with 666 species (58% of the flora). Species with very broad geographical area follow with 271 species (24% of the flora). Correlation between habitat and phytogeographical groups has been established. The predominance of the basic Guineo-Congolian element in forest sites where the human influence is lesser displays the stability of these habitats. The importance of species with very broad geographical area in grassy habitats illustrates the secondary or substitution character of these sites, mainly created by human activities. |
