North American Invasive Species Management Association Webinar Series

March 15, 2023 @ 1:00 pm - 2:00 pm CDT: Webinar: Preventing the Spread of Invasive Species through PlayCleanGo and WorkCleanGo

PlayCleanGo®: Stop Invasive Species In Your Tracks® is NAISMA’s official, branded, registered, trademark-protected education and outreach program aimed at stopping the spread of invasive species invasive species
An invasive species is any plant or animal that has spread or been introduced into a new area where they are, or could, cause harm to the environment, economy, or human, animal, or plant health. Their unwelcome presence can destroy ecosystems and cost millions of dollars.

Learn more about invasive species through outdoor recreational pathways. The international campaign is grounded in a Community Based Social Marketing (CBSM) strategy. NAISMA partners and PlayCleanGo supporters share prevention communication through social channels, as this proven outdoor recreation focused campaign aims to prevent the spread of invasive species by effecting behavior change and reminding recreationists to clean their gear every time they go to their favorite or a new recreation area. This is achieved through positive messaging that resonates with recreationists’ and field workers’ values, and includes a clear call to action to clean boots, boats, and other outdoor gear.
