    Abstract

    Peat land conversion to be the oil palm plantation affects on the ecosystem changing from peatland forest to monoculture of oil palms, thus inducing alteration of soil physical, chemical and biological characteristic. Biological properties of soil getting its impact is earthworm. Those soil animals are an important role in improving soil fertility. This study aimed to analyze the abundance and distribution of earthworm in peat land with different age of oil palm growth (2 years, 10 years, 15 years, 19 years and 23 years). The results showed that only one species of earthworm was found that is Pontoscolex corethrurus (Oligochaeta : Glossoscolecidae) in stand of oil palm age of 2 years , 19 years and 23 years. At the location study periodically inundated known from the measurement of groundwater table depth during the study, there were not found earthworms (at stand age of 10 and 15 years. Earthworm population density of P. corethrurus tended to increase with enhancing the stand age of oil palms (at stand age of 2, 19 and 23 years), whereas their distribution pattern based on analysis of the Morisita index was a clustered pattern. The clustered pattern of earthworm in young age oil palm stands is stronger than at locations of palm stands of old age.
