About Us
Who are we anyway?
The Yukon Invasive Species Council (YISC) is a non-profit organization committed to protecting the Yukon’s natural ecosystems, communities, and economies from the harmful impacts of invasive species. We are the only organization in the territory focused exclusively on invasive species prevention and management. Our work is rooted in collaboration, scientific knowledge, and a deep respect for the land.
Since our founding, YISC has played a leading role in raising awareness, coordinating community-based action, and informing policy to prevent the introduction and spread of invasive plants and animals. We host public events like weed pulls, deliver educational workshops across the territory, support youth and volunteers, and advocate for long-term strategies that prioritize early detection and rapid response.
We believe that meaningful change happens when people are informed, empowered, and connected. That’s why our work spans everything from creating accessible plant ID guides to collaborating with diverse stakeholders. Whether you're a landowner, student, volunteer, or policymaker, there’s a place for you in Yukon’s fight against invasives—and we’re here to support you every step of the way.
