Aquatic Plant Research Invasive Availability in Horticultural Stock

Concerned citizens from around the state reported that aquatic invasive plants were readily available in pet stores and garden stores despite regulations prohibiting the sale of certain species that had been in effect since 2009. DNR Science Services investigated whether education and outreach increased the rate of NR40 compliance by live aquatic plant retailers. Plants available for sale were surveyed in stores before and after one of two education programs. Stores were either sent a mailing about invasive species regulations or sent a mailing and visited by the DNR invasive species educator to talk about regulations, plant identification, and best management practices. Education did improve compliance with regulations (from 51% noncompliance by retailers down to 26% noncompliance), and visiting stores was more effective at improving compliance than the mailer.
