“…Regarding chorology, the importance of Sudanian base element species (20.63%), afro-tropical species (16.84%) and sudano-zambezian species (14.32%) compared to other phytogeographical types shows that Sudanian species and Sudano-Zambezi species are well represented on the study site. These results could be explained by the mountainous regime of Péni Classified Forest creating a microclimate favorable to the installation of Sudano-Guinean species, which confirms the assertions of Nguinambaye et al (2015). In addition, the predominance of Sudanian element-base species over other phytogeographical types is a characteristic of Sudanian savannahs (Pallo & Sawadogo, 2010).…”

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%

“…The flora of these two forests is largely dominated by phanerophytes. This predominance of phanerophytes has been highlighted by previous studies, including those of Ouoba (2006) and Nguinambaye et al (2015). At the level of vegetation units, the analysis within phanerophytes indicates that mesophanerophytes dominate all these units.…”

The biodiversity of community forests is poorly studied in Burkina Faso. This results in a lack of understanding of their ecological importance, which is characterized by neglect in their management. The main objective of this study is to characterize the flora and woody vegetation of the community forests of Rogho and Boala to demonstrate their importance. For this purpose, a forest inventory was conducted using stratified random sampling methods. Shannon, Simpson, Margalef, and Pielou diversity indices reveal significant biodiversity of the flora in both forests, with a better distribution of individuals within the species that make them up. The horizontal structure of the two woody populations is characterized by a predominance of individuals with small diameters (DBH € [5cm-25cm[) on either side, with respective regeneration rates of 58.36% and 22.46% for Rogho and Boala. Regarding the ecological importance of species, Lannea microcarpa has the highest Importance Value Index (IVI = 99.06) for the Rogho site, and Vitellaria paradoxa for the Boala site (IVI = 136.58). Phanerophytes dominate the flora of both forests with a strong presence of mesophanerophytes. The average density of woody plants is evaluated at 330.34 trees/ha and 742.01 trees/ha respectively in Rogho and Boala, with respective average land areas of 14.8 m2/ha and 119.78 m2/ha. This study highlights the strong ecological potential of the forests studied. Communal and regional authorities must develop strategies for the sustainable management of these forest areas.

“…Ainsi, on a distingué les espèces à large distribution géographique, les espèces à distribution continentale et les espèces de l'élément-base (espèces soudaniennes). Les références des types phytogéographiques sont celles de la subdivision phytogéographique de White (1986) utilisées par plusieurs auteurs au Burkina Faso (Ouoba, 2006 ;Mbayngone, 2008 ;Ouédraogo, 2009). Il consiste à établir les spectres phytogéographiques sur la base des grandes subdivisons chorologiques établies pour l'Afrique (White, 1986).…”

Les forêts classées sont des aires de conservation de la biodiversité en Afrique de l’Ouest. La présente étude a été initiée afin d’évaluer la diversité de la flore de la forêt classée de Kuinima à l’ouest du Burkina Faso. Les données ont été collectées par inventaires floristiques. Les caractéristiques des ligneux ont été obtenues à travers un échantillonnage stratifié dans des placettes de formes adaptées aux formations végétales. La méthode des points quadrats a permis de mesurer les paramètres des herbacées. Au total, 254 espèces dont 158 herbacées, 92 ligneux et 4 sub ligneux ont été dénombrées. Ces espèces appartiennent à 61 familles et 175 genres. L’analyse de la structure a montré une densité moyenne de 116 pieds de ligneux à l’hectare avec une surface terrière globale de 2,05 m2 /ha. L’ensemble des paramètres étudiés révèle que la végétation de la forêt de Kuinima est de type savanicole, constituée d’un peuplement à dominance arbustive. C’est une forêt qui subit des perturbations d’origine anthropique, mais demeure un refuge de la biodiversité végétale. Ainsi, des mesures rigoureuses de conservation doivent être entreprises pour sa réhabilitation et sa survie. English title: Diversity and floristic structure of plant formations in the Kuinima classified forest in the Sudanian zone of Burkina Faso Classified forests are biodiversity conservation areas in West Africa. The present study was initiated to assess the diversity of the flora of the Kuinima classified forest in western Burkina Faso. Data were collected by floristic inventories. The characteristics of the woody plants were obtained through stratified sampling in plots with shapes adapted to the plant formations. The quadrat point method was used to measure herbaceous parameters. In total, 254 species were counted, including 158 herbaceous, 92 woody and 4 subwoody species. These species belong to 61 families and 175 genera. The analysis of the structure showed an average density of 116 woody plants per hectare with an overall basal area of 2.05 m2/ha. All the parameters studied reveal that the vegetation of the Kuinima forest is of the savannah type, consisting of a stand dominated by shrubs. It is a forest that is subject to anthropogenic disturbances, but remains a refuge for plant biodiversity. Thus, rigorous conservation measures must be undertaken for its rehabilitation and survival.
