Impact DescriptionThe obstruction of sunlight caused by dense mats of Pistia stratiotes and Pontederia crassipes (water hyacinth) resulted in a reduction of the total amount of plankton and species diversity of plankton present in the impoundment being studied. This diminished primary production, and lead to a decreased level of water turbidity.
