The Alberta Invasive Species Council (AISC) is a not-for-profit society dedicated to informing and educating Albertans about the destructive impacts invasive species have on our environment, economy, and society.

We endeavor to foster partnerships with jurisdictions, agencies and groups to collaboratively develop integrated, long-term management programs, and to engage and empower people to take action against invasive species in Alberta.
