Welcome to the Trans-Canadian Research and Environmental Education (TREE) website, done in partnership between the Mistik Askiwin 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. With the TREE program, students from across Canada can be part of a national research program to study the environmental history of their own community.

Participation

Participation in this program requires that you commit to helping your students discover the environmental history of your community (constructing a timeline), registering with us to schedule delivery of equipment, collecting and sending to us at least 2 trembling aspen tree cores with associated soil samples according to instructions and the timeline you have created, and then sending the kit, samples, and timeline back to us. There is no cost! The TREE program is offered with the generous support of PromoScience (a program of Natural Sciences and Engineering Research Council of Canada).
