What Stories Do TREES Tell Us?
Welcome to the Trans-Canadian Research and Environmental Education (TREE) program! A citizen science program where students from across Canada join with researchers from the Mistik Askîwin Dendrochronology Lab (MAD Lab) to learn about the stories trembling aspen trees tell and how a synchrotron can be a tool to tell that story. Join us as we explore this new area in research and learn about environments across Canada!
Contribute to Citizen Science
How? Collect trembling aspen and soil samples. Check out Module 4 for instructions and what is in our TREE kits!
A timeline must also be provided. Connect with Module 2 to learn what historical data is needed for the research.
Help Advance Science Research
Join our Research Team as they study tree growth and the connection to chemical composition in tree cores and soil.
Why trembling aspen? MAD Lab is interested in learning how trembling aspen adapt to various Canadian environments.
Why a synchrotron? This is a new area of research for dendrochronology and with your help, we can help expand the science!

How to Participate
The TREE program connects to science research done in partnership between the Mistik Askîwin Dendrochronology (MAD) Laboratory and the Canadian Light Source (CLS), both on the University of Saskatchewan campus in Saskatoon, Saskatchewan. We acknowledge that the campus is located on Treaty Six land in the traditional territories of the Nêhiyawak (Cree), Anishinabek, Lakota, Dakota and Nakota Nations, and the homeland of the Métis. As educators, we respect Indigenous Ways of Knowing and oral traditions. We dedicate ourselves to moving forward in the spirit of partnership, reconciliation, and collaboration.
