There are many factors that can cause an overgrowth of weeds and algae in your lakes and wetlands. The scientists at Aquatic Systems do a thorough evaluation to determine the root causes before we recommend control methods.

It is important to remember when managing Florida waterbodies that some of our native plants can also become very weedy and require some form of management. Examples of this are our native Eelgrass (Vallisneria americana) and Slender Spikerush (Eleocharis baldwinii). Our scientists conduct research with some of the more invasive exotic aquatic weeds including Rotala (Rotala rotundifolia) and Crested Floating Heart (Nymphoides cristata), both of which are currently making their way farther north into Florida.

Managing invasive species while bringing back a healthy balance of Florida native aquatic plants may include a combination of biological control, chemical application, nutrient abatement , aeration and mechanical removal.

Our goal in conducting research is to understand and provide maximum results with the least potential harm to surrounding plants in the environment.
Our scientists perform mesocosm (aquarium) testing using a variety of structured protocols in our Aquatic Plant and Algae Lab. This enables us to develop truly customized Integrated Pest Management plans. Field experiments  are undertaken that either confirm lab results or provide us with better direction for subsequent testing.
Sam Sardes, our Weed Science Director, is a native Floridian responsible for all of the testing of chemicals, plant ID and algae. Her Education and experience include:
• M.S. in Agronomy, University of Florida
• B.S. in Biology, Florida Atlantic University
• Student Director for the Aquatic Plant Management Society 2016-2017
The Science Team at Aquatic Systems takes pride in fine-tuning traditional management practices,  developing novel techniques and collecting empirical data to support their use. They regularly conduct  lab and field experiments to identify aquatic plants recently introduced and monitor for invasive behaviors. Field experiments are conducted with the assistance of our Regional Biologists and Service Teams, who are trained in field data collection so that we may conduct research throughout the state of Florida at any time.
