Although earthworms have been recognized as important soil macro-invertebrates that influence
soil functioning in the past two decades, little attention has however been devoted to the diversity
of these organisms. The lack of a rapid method to efficiently assess the abundance and diversity
has been a major cause of their neglect in tropical ecosystems. Thus, the challenge for soil
ecologists is to develop an efficient method to assess earthworm diversity. In this paper, we
proposed an integrated rapid protocol to assess, at both local and landscape scales, the
abundance and diversity of earthworms, in the framework of the ?Conservation and Sustainable
Management of Below Ground Biodiversity? (CSM-BGBD). This method consist in a combination
of the so-called ?TSBF soil (25x25x30cm) monolith? and a set of 3 large soil monoliths (50x50x20
cm), randomly chosen at the sampling point. This method aims to satisfy the requirement of
rapid assessment of earthworm and the need to take into account soil heterogeneity at plot
level. Results show that with both small and large monoliths, significant changes were obtained
in earthworm abundance and diversity, following human-induced disturbances of the ecosystem.
However, species richness, the Shannon-Weaver index and cumulated species richness were
significantly higher using the large monoliths. Moreover, sampling efficiency was significantly
higher using the large monoliths (98.2±0.8%), as compared to the small ones (86.01±4.4%).
The contribution of this protocol to efficiently assess the diversity of tropical earthworm
communities and the implications for data processing are discussed. MenosAlthough earthworms have been recognized as important soil macro-invertebrates that influence
