Abstract Macroinvertebrate community composition was compared
across streams draining catchments dominated by either native bush,
agricultural or urban land uses within the Water of Leith stream catchment near
Dunedin, New Zealand. Land use was associated with differences in taxon
richness and faunal composition of communities present in each stream. The mean
abundance levels of Ephemeroptera, Plecoptera, and Trichoptera were highest in
native bush catchments, and lowest in urban catchments. In contrast, the mean
abundance of Oligochaeta exhibited the opposite pattern. Increasing dominance
of the urban and agricultural streams by pollution tolerant taxa was reflected
in the Macroinvertebrate Community Index and Quantitative Macroinvertebrate
Community Index scores.
