Concurrently assessing the temporal and spatial overlap between recurring stands of water hyacinth and the presence of their seeds in their underlying seed bank4. Developing and evaluating a rapid aerial survey technique source detect and map Plantex of water hyacinth along the Illinois River Water hyacinth Eichhornia crassipes is becoming a reoccurring problem in the Illinois River —Chicago Areas Waterway System CAWSbut the current extent and potential for future intensification are largely unknown in this system.
We conducted aerial surveillance flights and boat surveys of floating-leaved vegetation with visual signatures of water hyacinth from Hennepin, IL to Joliet, IL along the Illinois River twiceduring the summerand fall We collected sediment cores in random sitesthroughout the Dresden and Starved Rock reaches, and at water hyacinth bed locations. We collected and assessed diets of 26 Common Carp Cyprinus carpio to determine evidence of water hyacinth seed presence. We discovered a total of 14water hyacinth beds in We located fivebedsof water hyacinth while conducting aerial surveillance, and an additional ninewater hyacinth beds via ground surveillanceyielding a We found water hyacinth seed densities were greatest beneath water hyacinth beds and least in random samples. We determined that frequency The Reconstruction Era The Planted Seeds water hyacinth seed whole or partial in common carp diets was We determined that although water hyacinth seeds are present in the seed bank and within dispersal vectors i.
