Stewards meeting at Todmorden Mills Wildflower Preserve, 2021
Stewardship on Public Land

TNS History

We have evolved from TRRS (Toronto Ravine Revitalization Science) into Toronto Nature Stewards (TNS), partnered with U of T’s Institute for Forestry and Conservation and other conservation minded citizens and organizations.  We remain solidly based in science and best practice, but are more action-oriented.  Our partnership with U of T provides access to research, experts and students which we continue to rely on to fulfill our mandate.
