The use spectrum of the twelve most species-rich plant families in Burkina Faso. The bars represent the percentage of species in the respective family used in four different use categories. The three most important use categories (traditional medicine, human nutrition and animal fodder) as well as other uses are shown. Other uses include the use for construction, tools and crafts, firewood, ornament, veterinary as well as religion and art. The use patterns differ considerably. Large proportions of the Apocynaceae, Euphorbiaceae and Lamiaceae are used for medicine. Cyperaceae and Convulvulaceae are generally scarcely used.
