ABSTRACT: Protected areas contain most of Burkina Faso’s plant biodiversity which
confer different benefits for the communities. However, the composition of some
of them remains unknown. In a context of overexploitation and climate change,
it is important to have a detailed knowledge of the vegetation of forests that
have not been studied, such as Péni Classified Forest (PCF) to develop better
preservation protocols. The aim of this study is to contribute to the knowledge
of the flora of Burkina Faso. Phytosociological surveys were carried out in 213
plots, have identified 475 species distributed in 321 genera and 87 families. We identified during this study
201 woody species representing 38% of the woody flora of Burkina Faso.
64% of this flora is confined to shrub savannahs and 61% to tree savannahs.
Among the vegetation units, shrub savannahs and tree savannahs have
respectively 56.21% and 44.67% of very rare species.
Poaceae (11.90%), Fabaceae-Faboideae (11.27%) and Rubiaceae (6.26%) are
the most dominant families. The dominant biological types of the flora are
phanerophytes (42.32%) and therophytes (30.32%), and Sudanian species (20.63%)
are the best represented. Logging is the most frequent disturbance factor
(100%) in the PCF. The PCF is a particular ecosystem with a great diversity but
subject to many disturbances. Actions to strengthen its protection are
necessary.
