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 have Canada joined 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.

TREE 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.
