Greg Hitzroth is IISG’s new aquatic invasive species specialist, working out of the Chicago Botanic Gardens in Glencoe, Illinois. Greg will design and implement public outreach programs and resources designed to increase awareness of the spread of invasive species introduced to the waterways of Illinois and Indiana through commercial trade. He will also work closely with IISG’s Aquatic Invasive Species team to identify and partner with outside stakeholders, including suppliers of non-native species, to ensure greater public awareness of the impact of organisms in trade and strategies for reducing their movement into the Great Lakes region.

 
Greg holds a MS in Biology from Northern Arizona University. He joins IISG after a three-year tenure as a research assistant for the Plants of Concern Program at the Chicago Botanic Gardens.

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)
