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.

Her love for the natural resource field again came to the forefront after a move to rural Northern Alberta where she fell in love with the Boreal Forest. She has worked in the Safety, Oil & Gas and Construction Industry before moving into the Natural Resource areas of Weed Inspecting, Forest Health and joining the AISC as a Social Media and Invasive Species Specialist in 2018.

Wayne Ungstad – Director
My early memories as a child were of a favorite willow tree Salix discolor and my hours of contemplation in its shade. I spent hours intrigued by the diamond shapes on the trunk later to learn the wood had been deformed by a fungus which had produced the diamond shaped segments with its alternating colours.
I started reading Thoreau and Leopold; learning nature had virtue and the ethics gleaned from the interactions with ecosystems could be applied to life. Later, as an adult I understand that when we destroy nature we lose more than wildlife; we lose a sense of our humanity as well. Wayne is an agricultural producer who is involved as an ENGO with natural resource management frameworks.
