Number of plant photos recognized by participants of different reported ages. Participants identified plants from a set of 25 pictures of a medicinal plants (General Linear Model, r 2 = 0.77, DF = 36, p < 0.01), b fodder plants (General Linear Model, r 2 = 0.67, DF = 33, p < 0.01) or food plants (data not shown, GLM, r 2 = 0.48, DF = 31, p = 0.14). Participants identified plants by local name or clear description of its use or habitat. Ages were estimated by participants themselves and are only approximate
