For example, Afzelia
xylocarpa was not observed during remnant forest sampling
but was included, because the local forest expert indicated that
its absence in remnant forest was due to exhaustive logging, and
that it was in fact a primary forest species. Species for which less
than three individuals were encountered in all plots were also excluded,
as defining these as distinct species, or RTUs, was deemed
to be potentially problematic due to the issues with identification
described above. This particular technique was accepted in the
context of this study, but should be taken into consideration when
interpreting the results.
