Cette \u00e9tude r\u00e9alis\u00e9e dans la r\u00e9serve de faune d\u2019Abdoulaye (RFA) \u00e9value la dynamique des feux de v\u00e9g\u00e9tation et caract\u00e9rise la vuln\u00e9rabilit\u00e9 de la flore au feu de v\u00e9g\u00e9tation. Les donn\u00e9es d\u2019images satellitaires Landsat de 1999 et 2019 ont permis de suivre l\u2019\u00e9volution du feu dans la RFA. Des placettes de 1000\u00a0m2<\/sup> et 100\u00a0m2<\/sup> ont \u00e9t\u00e9 install\u00e9es respectivement pour l\u2019inventaire phytosociologique des esp\u00e8ces ligneuses et des plantes herbac\u00e9es. Les esp\u00e8ces pr\u00e9f\u00e9rentielles des zones br\u00fbl\u00e9es ou non br\u00fbl\u00e9es ont \u00e9t\u00e9 identifi\u00e9es \u00e0 travers leurs valeurs indicatrices. La caract\u00e9risation \u00e9cologique est effectu\u00e9e sur la base des descripteurs. L\u2019analyse de la dynamique du feu de la RFA r\u00e9v\u00e8le une diminution de 9,43\u00a0% des feux de v\u00e9g\u00e9tation entre 1999 et 2019. Au total 162 esp\u00e8ces v\u00e9g\u00e9tales ont \u00e9t\u00e9 recens\u00e9es dans la RFA. Ces esp\u00e8ces sont r\u00e9parties en 53 familles et\u00a0125 genres dont 101 esp\u00e8ces ligneuses et\u00a061 herbac\u00e9es. Les\u00a05 familles les plus repr\u00e9sent\u00e9es sont\u00a0: les Poaceae (31\u00a0%), les Combretaceae (10\u00a0%), les Sapotaceae (7\u00a0%), les Leguminosae-Cesalpinioideae (6\u00a0%), les Leguminosae-Mimosoideae (5\u00a0%). Un total de 118 esp\u00e8ces r\u00e9parties en 42 familles et 99 genres ont \u00e9t\u00e9 recens\u00e9es. Les esp\u00e8ces pr\u00e9f\u00e9rentielles des zones br\u00fbl\u00e9es sont\u00a0: Vitellaria paradoxa, Andropogon gayanus, Cochlospermum planchoni<\/em>, Sarcocephalus latifolius, Bridelia ferruginea, Daniellia oliveri, Heteropogon contortus<\/em>. Les esp\u00e8ces pr\u00e9f\u00e9rentielles des zones non br\u00fbl\u00e9es sont\u00a0: Cola gigantea, Anogeissus leiocarpus, Diospyros mespiliformis, Holarrhena floribunda, Voacanga africana.<\/em> La variabilit\u00e9 de la composition floristique en fonction de la dynamique des feux implique une mise en place des strat\u00e9gies de gestion pour une conservation efficace de la biodiversit\u00e9.<\/p>\n
