Now that spring is finally here, many of us are thinking about gardening. Is this the year you put in a water garden? Or do you already have a water garden, and plan to add new plants? Well, before you head out to the garden center, you should know that water gardening is one way that invasive aquatic plants can spread into new waterways. When introduced into local waters, these plants can displace native ones, which are sources of food and shelter for native wildlife. Because they grow so prolifically, invasive plants can also clog drainage pipes, impede navigation, and make fishing difficult.

Does this make water gardening a bad idea? Not at all. It means you should be careful to choose plants that are native or non-invasive. It also means you should be careful how you get rid of plants you no longer want or need. For instance, do not release them into natural waterways.

IISG has a 4-page brochure, Invasive Aquatic Plants: What every Plant Enthusiast needs to Know, that provides tips on how best to situate your water garden and how to choose plants carefully. You might want to take the “Most Wanted List,” included in the brochure, with you to the garden center. These are the baddest of the bad invasive plants.

Join the Invasive Crayfish Collaborative for an exciting webinar featuring Dr. Chris Taylor from the Illinois Natural History Survey who will provide an overview of midwestern crayfish habitat requirements, feeding, reproductive biology, and life-history.Crayfishes in the Midwest occupy almost every type of aquatic and semi-aquatic habitat in the region. They function as critically important components of those ecosystems and in many cases represent a majority of invertebrate biomass. As “keystone” species, understanding their biology and roles in ecosystems is critically important. Register for the webinar at InvasiveCrayfish.org/events1 Or the link in bio.
