Abstract
The effects of habitat degradation on
biological endpoints were studied at 13 sites in and
adjacent to the South Fork Broad river basin. Constrained
ordination was used to relate benthic macroinvertebrate
and fish data to habitat and environmental data. Benthic
macroinvertebrates were primarily influenced by habitat,
while fish were affected by stream order and secondarily
by habitat. Habitat degradation was related to: a decrease
in stoneflies, caddisflies, and the Clingers/Burrowers
ratio; a decline in the abundance of darters and suckers;
and an increase in the number of sunfish species.
