Abstract

A quantitative ethnobotanical method based on structured interviews was used to evaluate local use-preferences and dynamics of practically all woody species in the Sahel of Burkina Faso. One hundred Fulani informants estimated the value of 56 woody species for food, firewood, construction, medicine, field trees, shade and fodder, as well as conservation priority, abundance and dynamics of each species. There was a large consistency in answers, but significant between-village differences existed. Gender and age of informants did not influence answers significantly. The present valuation method identified a large number of species important for local use and demonstrated a more varied plant use than seen from free-listing interviews. Furthermore, the Fulani informants described a decline of practically all woody species. The present valuation provided management-relevant information about plant use and vegetation change. The woody vegetation in the Sahel is currently without sufficient management to uphold a rational use of the vegetation, following the gradual disappearance of the traditional nomadic trekking routes that previously helped to ensure a rational use of the vegetation.
