On the low fluvial terraces of the Caqueta River, Araracuara region, Colombia, age-differentiated plots of secondary and primary forest have been compared with regard to the species composition and the forest structure. Plots shortly used for agriculture are readily invaded by various species of the Cecropiaceae, Guttiferae, Melastomataceae and Palmae. Species diversity of the early seral stages is comparable to early climax clearings. Approximately 80 years after, the structure and species composition are almost identical to those of primary forest. The local traditional cultivation system is environmentally sustainable, however, the population explosion could eventually lead to the pressure on forest land.
