Each year, Great Lakes beach managers have to remove trucks full of slimy algae from the beachfront areas to keep them enjoyable for residents and visitors. But it can be a costly process and a regular need that could be met in a more environmentally friendly way.

“Truckloads of the stuff are hauled to landfills every week or so, but beach managers want a greener and cheaper method of disposal.
 
‘Algae removal is sort of a routine beach-grooming thing that we do, but because it’s wet and heavy, it can be expensive to dispose of,’ said Cathy Breitenbach, director of Green Initiatives for the Chicago Park District, which is responsible for 26 miles of lakefront in the city. She’s hoping to find an alternative that saves taxpayers money and is more sustainable than taking it to the dump like the district does now.
 
Composting may seem like an obvious solution, but it’s not as simple as it sounds, say algae experts. Cladophora mats can harbor large concentrations of bacteria, including some potentially dangerous varieties.
 
‘We have evidence to show that E. coli bacteria are found in very high densities in Cladophora mats,’ said Murulee Byappanahalli, a research microbiologist at the U.S. Geological Survey’s Lake Michigan Ecological Research Station in Porter, Ind.”

Coastal protection is not limited to concrete, rocks, and steel. Coastal protection solutions exist on a spectrum, ranging from softer “green” solutions to harder “gray” structures.Nature-based coastal solutions fall between green and gray techniques, providing multiple benefits to people and habitats.Our three-part video series, Nature-Based Coastal Solutions in the Great Lakes, is now available to watch. Learn how nature-based coastal solutions, including nature-driven and hybrid approaches, can protect shorelines while supporting ecosystems and communities.Watch the 3-part video series at the link in bio.(Photo credit: Liz Spitzer, Illinois State Geological Survey, Coastal Research Group)
Managers and researchers can be faced with a need to classify the risk of new crayfish invaders. Rapid assessment tools, such as the Science-based Tools for Assessing Invasion Risk (STAIR), can assist in this process by providing a streamlined framework for analysis and decision-making.Join us for an ICC webinar with John Bieber from Loyola University Chicago to learn how rapid assessment tools are used to classify invasive species risk and how STAIR can support invasive crayfish management.Learn more at the link in bio.
