  • Plant biomass was measured in forest regrowth on fields abandoned after a cycle of raingrown rice following clearing and burning. Its evolution, with that of the main components (Macaranga hurifolia, lianas, Marantaceae, Zingiberaceae, miscellaneous
  • species), was followed through eight stages from a rice field at harvest to secondary forest 40 years old. The last stage had a biomass of 230 t/ha, about half the average value for forest in this area. The annual increase in above-ground biomass was 5.75
  • t/ha/year. The changes in biomass of the different components show the part played by each in the evolution of the plant cover reconstituting the forest. The results are compared with those from other tropical regions.
