Description

Savannas subjected to seasonal flooding occupy· vast areas of the Tropics. Above-ground bio­mass values for Venezuelan flooded savannas are high and related to the longer availability of water. C3 plants colonized the waterlogged unit and showed the highest productivity and nutritive value. This natural system permits a prolonged grazing season. These first results show the great potential for animal production of this ecosystem, stressing the need for coor­dinated research efforts in order to gain a better understanding of it.
