Aquatic Macro-Invertebrates
A total of 66 macro-invertebrate taxa were recorded in the pipeline LSA
(Table 4.3-3). Both diversity and abundances of the macro-invertebrate fauna
were high. Aquatic macro-invertebrate diversity and abundance were generally
higher at undisturbed primary forest sites than deforested locations; the highest
species richness of 22 to 23 species were recorded at sites 042+300, 051+600,
and 060+600, all located in undisturbed primary forest (with IHIA classifications
> B; Table 4.3-1) associated with the drainages from the eastern border of
Mantadia National Park.
