Using native aquatic plants like those in Jens Jensen Park is about more than just creating striking water gardens, though. Growing native species also helps curb the spread of invasive aquatic plants that outcompete native species and upset food webs. Invasive species common in water gardens are already threatening the health of Illinois waterways. For example, the fast-growing Brazilian Elodea—typically sold in aquarium stores and water nurseries under the name “Anacharis”—has been found in several lakes and ponds in Illinois, including in a community not far from Highland Park. Like many invasive plants, this waterweed grows in dense mats that block out sunlight needed by other species and hinders water recreation. And it is nearly impossible to remove once it has been introduced.

Tune into a new episode of the Everyday Environment Podcast featuring IISG Great Lakes Contaminants Specialist, Sarah Zack! Plastics, medications, and cleaning products might seem harmless at home—but once they enter our waterways, they can become contaminants of emerging concern.
In Everyday Environment’s recent blog and podcast, Sarah shares how everyday choices can help reduce pollution and protect aquatic ecosystems.
