This contribution reports the results of a 16 months study of a burned grassland. Changes in species composition and in the dynamics of various aboveground compartments, net aerial primary productivity, plant mortality, rates of litter fall, and dissapearance of dead material are given. The study site was located in Sierra de la ventana (38 6' Lat. S, 61 56' Long. WG) which is elevated several hundred meters above the Pampas of Argentina. The environmental setting of the grassland as well as the meteorological consitions before and after the fire also discussed. In the first year after the fire plant diversity increased, the biomass of certain successional and exotic dicots also increased and the patways of dead organic flux to the ground changed from a sequence of live - standing dead - litter to live - litter. However, with the reestablishment of climax species plant diversity decreased, successional and exotic dicots decreased in importance, dead organic matter accumulate and the pathway organic flux returned to the pattern that was characteristic before the fire. |
