Distribution et fréquence d’occurrence des plantes vasculaires au Parc National de la Ruvubu, Burundi.

In order to highlight the distribution of frequencies of plants with the purpose of natural heritage preservation, an analysis of occurrences of vascular plants based on botanical observations in a set of 114 sample plots has been conducted in the Ruvubu National Park (Burundi). Analysis of the general list (richness) of the flora shows on one hand the specific richness variation of families within ecosystems, and on another hand species with particular statute by their frequencies of occurrence. Within the protected area, evenness indicates a light balance in plant distribution. Nevertheless, unevenness is observed in savannas whereas species distribution in the forest galleries and swamps is relatively equitable. Ten species are listed on the IUCN threatened species list of Burundi which corresponds to a high priority for conservation. These species may warrant special conservation effort and spatial analysis of their potential distribution in Burundi in order to assess species deterioration and the spatio-temporal dynamics of ecosystems that shelter them. © EuroJournals Publishing, Inc. 2010.SCOPUS: ar.jinfo:eu-repo/semantics/publishe
