“Grass carp, a plant-eating species of the invasive Asian carp family, have also been found spawning in Lake Erie and its many tributaries…Though fears over invading Asian carp have largely centered on bighead and silver carp — which gulp down large amounts of plankton, the all-important food-source foundation for a healthy aquatic ecosystem — the new study suggests conservationists should pay attention to grass carp too.Grasses are also an important nutritional source for native fish species, and as its name suggests, grass carp could prove detrimental in that department.The U.S. government has already spent upwards of $200 million trying to slow the encroachment of Asian carp into the Great Lakes. Many worry their growing presence will turn the Great Lakes into one giant carp pond — ruining ecological diversity and the multi-billion dollar fishing industry in the region. Regional authorities remain in discussion with federal agencies over further mitigation efforts.”

In late July, formal and non-formal educators joined @nature_indiana, @indianadnr Division of Nature Preserves, and @lakecountyparks for a workshop exploring ecological restoration in the Grand Calumet River Area of Concern.
Participants toured restored sites in East Chicago and Hammond, engaged with experts in sediment remediation and habitat restoration, and experienced a cutting-edge Virtual Reality curriculum aligned with NGSS for grades 6–12.
From industrial past to ecological renewal, educators left inspired and equipped to bring local environmental stories into their classrooms.
