Buena Vista
Rapid bio-assessment methods were applied to
benthic macro-invertebrate community structures at two different sites on the
channelized groundwater ditches of the Buena Vista marsh, southwest Portage
county. Three replicate samples
were collected from snag and riffle habitats at each site.
Calculated metrics were then analyzed for correlation to quantified
nutrient levels at the sampling sites.
In addition, the resulting FBI metrics and community structures were compared
between snag and riffle habitats, as well as between the two different ditches
utilized in the study area.
Dates: Specimens and data are collected in the fall. Data is compiled and specimens are identified throughout the
winter months.
