Growth of a logged-over tropical rain forest of the brazilian Amazon
Growth of a tropical rain forest of the Brazilian Amazon was monitored for a period of eight years after experimental commercial logging operations. Average diameter growth rate was 0.5 cm year, comparable to similar results elsewhere. Increment of individual trees was not correlated with tree size but a strong correlation was found when mean increment by diameter class was considered. Light had a strong influence on growth. Trees receiving full overhead light grew up to three times faster than trees reciving only side on diffuse light. The beneficial influence of canopy opening on growth disappeared three to four years after logging although individual species kept high increment rates even eight years after logging.
