Description:	Species composition, abundance and biomass of these earthworms were determined in a polyculture forestry plantation (POA/C) and in plots of nearby secondary (SEC) and primary (FLO) forests in Amazonia. The earthworms were collected using the formol extraction method. In five collections, between July 1997 and June 1998, only seven species were found (mainly Glossoscolecidae). One peregrine species (Pontoscolex corethrurus) was found in the polyculture plot and another (Dichogaster bolaui, Octochaetidae) nearby. The abundance of earthworms in the three plots is low for tropical rain forest sites (<1 ind m-2 - 5.5 ind m-2 compared to 1 ind m-2 - 189 ind m-2) but biomass (up to 20g fresh weight per square meter) is among the highest numbers ever found in rain forests.
