The quality of the riparian habitat (FHI, QBR) and that of the
riparian macroinvertebrate community (taxon richness, IBMWP,
IAST) decreased substantially from upper to middle sites (Table 2)
reaching relatively low values in downstream sites. Exceptions
included the upstream site L2whichwas located in a private fishing
and camping resource and hence showed its riparian habitat moderately
altered and site B1 during Spring, which showed a relatively
lowtaxon richness and lowIBMWPscores, probably due to episodic
or accidental effluent discharges coming from an upstream STP.
