ABSTRACT: In Senegal, natural pasture plays a major role in feeding livestock. During the rainy season, herbaceous plants account for a large proportion of the fodder consumed by ruminants. In Casamance, the composition and quality of these grasses are poorly known and underexploited. In this context, the study aimed to improve the knowledge and valorisation of the herbaceous fodder of the South. Individual interviews were conducted and a questionnaire was sent to farmers living in Ziguinchor and Kolda. A floristic inventory with a phytosociological approach was also carried out. The data collected were processed using Excel and Sphinx software in order to differentiate and classify the herbaceous species eaten by the tail. The majority of respondents were Fulani (55.30%). most of whom ranged in age from 30 to 60. Livestock rearing came second (38.3%) after agriculture (40%) among the principal activities of the people surveyed. The floristic inventory identified 95 species in 68 genera and 22 families. Species of low and medium pastoral value dominate the herbaceous layer. The global rangeland quality index was 48.16% and the brute pastoral value was 54.77%. Thirteen species contributed 54.86% of the pastoral value of the grassland. The floristic composition of community rangelands showed the presence of a varied herbaceous fodder range. The combination of which will help to develop a table of nutritional values for the formation of equilibrated feed rations for farmed livestock.
