The methodology recommended by the Tropical Soil Biology and Fertility Program (TSBF) was used. Macrofauna density, biomass, and diversity of earthworm species varied considerably across land use types, and depths. Principal component analysis yielded three factors that accounted for 71.8% of the total variance in macrofauna density. High taxonomic units values occur in the Andean forest (98 observed), decreasing dramatically in pastures (ranging from 28 to 13) and farm lands (ranging from 31 to 18).
