The productivity of 3 savanna communities from a 1-km2 area in N. Senegal was studied. A community dominated by Aristida mutabilis, Blepharis linariifolia, Schoenefeldia gracilis and Polycarpaea linearifolia produced 81.6 g DM/m2 in 1970. An area with Chloris prieurii, Brachiaria hagerupii and Panicum laetum yielded 255.7 g DM/m2 and an area of Panicum humile, Andropogon spp., Echinochloa colona and Blainvillea spp. yielded 476.4 g DM/m2. Below-ground biomass was lowest for the 1st of these communities.
