NAISMA (North American Invasive Species Management Association) is the organization behind National Invasive Species Awareness Week and the PlayCleanGo program. They hold regular educational webinars that are free when given live, and host a library of past webinars that are usually available to members only. As a way to support the invasive species management community and the general public during the COVID-19 pandemic, they've unlocked all of their webinars through the month of April!
