Join us for PlayCleanGo® Awareness Week, taking place June 6-13, 2026, across North America. This annual campaign brings together outdoor enthusiasts, land managers, and partners across the U.S., Canada, and Mexico.
Seed dispersal is a natural process that helps keep ecosystems healthy and resilient. However, when people visit parks, they can unknowingly carry seeds on their boots—including seeds from invasive plants—which can change what grows where.
Invasive species are one of the main drivers of biodiversity loss worldwide and different countries have taken different approaches to communicating this to society taking into account culture, language, and local traditions.
