This study describes the community structure of earthworms along a gradient of Land Use Intensity (LUI) in the forest margin zone of southern Cameroon. The high LUI block is severely deforested; medium LUI is moderately deforested and low LUI is largely forested . In each village, earthworms were collected during the rainy season in 5 Land Use Systems (LUS) of different levels of disturbance by hand sorting 5 monoliths (50 x50 x 30 cm). The sampled LUSs were: secondary forest 30 years old (Sfor), shaded cocoa plantation (Cacao), young forest of 12-15 years (Yfor), 4-5 year old Chromolaena odorata (Chr) and a groundnut/maize/cassava intercrop (Crop). Low LUI harbored more species (24) than medium (21) and high (18) LUI, yet differences were not significant. Epigeic earthworms in Yfor in the medium LUI were 3 times more abundant than endogeic earthworms and this LUS significantly outnumbered all the other LUS in earthworm abundance and biomass. Diversity was low but evenness high in all 3 LUI blocks. LUI had a significant effect on the diversity indices of all the LUSs based on species data. There was a significant effect of LUI (F=4.31, P=0.033) and a highly significant effect of LUS (F=7.35, P=0.0003) on Simpson's diversity index on a biomass basis. Principal Component Analysis and Correspondent Analysis on species data clearly separated the high LUI block from the other two but no difference was found between low and medium LUI blocks. High LUI harbored a completely different earthworm assemblage while low and medium LUI had a lot of species in common. Intensification is likely to be the factor determining this difference in community structures between LUI.
