Abstract



Interdisciplinary Research in Ecology Using GIS Technique at Kimmes Tobin
Track: Ecology and Conservation
Author(s): William Bajjali, Donald Davidson, Mary Balcer

A study of the water chemistry and distribution of aquatic plants in 14 ponds in the Kimmes Tobin wetland in Douglas County, Wisconsin revealed that a great variety of aquatic plants have colonized these shallow man-made ponds. The chemistry of the pond water differs from that of the source water which comes from rain and surface runoff. The pond water shows a shift from calcium to magnesium as the dominant cation. This shift is attributed to the interaction between aquatic plant roots, microorganisms, and red clay that dominates the bottom of the ponds. Nitrate concentrations have also been modified due to the adsorption of NO3- by the plants. The pH of the pond water has increased and be classified as hyperalkaline. The GIS have been an excellent tool for studying the spatial distribution of aquatic plants in the ponds and creating DEM applying IDW and Kriging techniques.
