This talk will review internationally accepted standard methods for the inventory of below-ground
communities and characterisation of land use in the humid tropics, as developed by the major
GEF/UNEP-supported international research project Conservation and Sustainable Management
of Below-ground Biodiversity (CSM-BGBD). This project has coordinated more than a decade
of intense discussion and widespread field work by a large number of expert scientists from
many countries and the protocols developed cover almost the full range of biological diversity
from the largest invertebrates through to fungi and eubacteria. The explicit aim is a practical
one: to provide a definitive tool to establish a baseline and then to document the loss of soil
biodiversity associated with deforestation and the process of agricultural intensification at forest
margins. Ultimately these tools can be deployed to better use soil organisms in ecosystem
management, in bioprospecting, and to achieve sustainable improvements in agricultural
productivity for the World?s poorest people.
Manuals of sampling methods for soil organisms have appeared at regular intervals for the past
50 years but have rarely drawn on indigenous expertise in countries which are most affected by
deforestation and land use change. CSM-BGBD brings together academic, institutional and
governmental organisations where new policies for land management must be devised, validated
and implemented if we are to have any chance of arresting the loss of tropical biodiversity. The
methods devised have all been developed and piloted under field conditions in 12 benchmark
locations distributed across 7 countries and three continents; consequently they are suitable not
just for taxonomic experts but for general biologists, agriculture specialists and technical staff
with all levels of training. The soil biota are grouped into 8 categories (including separate
considerations of macrofauna, mesofauna and nematodes), each of which has a broad taxonomic
identity but also corresponds to a major functional group considered important or even essential
to soil function and therefore to the many ecosystem services which soils provide. The process
has also embraced the revolution in molecular methodology that has swept through the biological
sciences during the last ten years, and has included extensive consideration of the place and
importance of replication in biological sampling below-ground. It is argued that these new sampling
protocols are 1) inclusive, i.e. designed to sample all eight biotic groups in the same field exercise;
2) spatially scaled, i.e. provide biodiversity data at site, locality, landscape and regional levels,
and to link these data to land-use and land-cover and 3) statistically robust by a partial
randomization of plot selection and by minimising pseudoreplication.
The advantages and disadvantages of transect-based and grid-based sampling methods will
be discussed, illustrated by published protocols ranging from the original ?TSBF transect?, through
versions developed for the Alternatives to Slash-and-Burn Project (ASB) to the final schemes
(with variants) adopted by CSM-BGBD. The publication of CSM-BGBD methods in book form
(Moreira, F.M., Huising, E.J. and Bignell, D.E. Eds., 2008. A Handbook of Tropical Soil Biology:
Sampling and Characterization of Below-ground Biodiversity. Earthscan Publications Ltd.,
