La relative abondance fourragère du l’ouest du Burkina Faso attire, depuis bien longtemps, des pasteurs du nord. Mais dans un contexte marqué par le changement climatique, la dégradation des pâturages de la zone estévoquée par les acteurs. Afin de mieux appréhender le phénomène, une enquête a été réalisée auprès de 166 éleveurs dans 11 localités de Batié. Il ressort de l’étude, 21 espèces herbacées dominées par les Poaceae (16 espèces) et 19 espèces ligneuses composées principalement de Fabaceae (8 espèces) appétées par les bovins identifiées par les éleveurs. De ces espèces, les plus appétées sont Andropogongayanus, Andropogon ascinodis, Pennisetum pedicellatum, Afzelia africana, Pterocarpus erinaceus et Khaya senegalensis. Hélas, 94,5% de la population d’étude indiquent que ces espèces appétées sont également les plus menacées de disparition. Cela est favorisé par plusieurs facteurs principalement d’ordre anthropique mais aussi naturel (déficits de pluies). A cela, s’ajoute l’envahissement des pâturages par des adventices selon 100% de la population d’étude. Toutefois, la majorité (98,7%) n’entreprend aucune action pour endiguer le phénomène essentiellement par méconnaissance des pratiques (53,7%) ou par manque de moyen et d’espace (32,3%). En somme, l’étude montre une diversité floristique mais qui est menacée de disparition. Elle appelle à des actions de restauration des pâturages et de sensibilisation des acteurs pour une utilisation saine des parcours.
