Local citizen nabs invasive plant on sight

Posted January 29th, 2015 in Aquatic Invasive Species

Water gardeners—keep your eyes open this season for invasive plants that may be lurking at your neighborhood garden store. In recent years, Illinois and Indiana DNR have both added nearly 30 new species to their lists of banned aquatic plants, but some may still be available for sale. 

 If you spot one of these invaders, be sure to tell the store manager. Some species can be hard to identify and larger stores may not even know these plants are on their shipment list. That’s exactly what was happening at a Petco in Carbondale, IL, where Karla Gage found Brazilian elodea—aka Egeria densa—while browsing with her family.  

“I notified the department manager that this was listed as an injurious species in Illinois, and I sent a follow up email to the store manager,” said Karla, coordinator of the River to River Cooperative Weed Management Area, which brings together federal, state, local, and private partners to tackle invasive plants in southern Illinois. “I received a call from the corporate contact, who stated that Petco stores in Illinois would no longer receive or be able to order Brazilian elodea. Previously, Carbondale stock had been on “auto-replenish,” so the stores never actually ordered Brazilian elodea. Current stock is being disposed of responsibly.”

 

“Thanks to Admin Code 805 and the quick response of Petco,” she added, “the risk of an introduction of Brazilian elodea into natural systems has been reduced.” 

The Illinois and Indiana rules also make it illegal to gift, barter, exchange, loan, or transport the any listed species. Recent additions to the list—27 plant species in Illinois and 28 in Indiana—were chosen based on the results of a risk assessment tool developed in Indiana by the Aquatic Plant Working Group. The tool evaluates species based on factors like ability to thrive in the Great Lakes and difficulty to control. IISG’s aquatic invasive species (AIS) team organized and facilitated the group, which included representatives from the aquatic plant industry, aquarium and water garden hobbyists, state agencies, academia, and non-governmental organizations.
