The Toronto Field Naturalists, University of Toronto Faculty of Forestry, and the City of Toronto have been doing many great researches in the ravines. Thanks to their pioneer work, we are able to use these historical baseline data to assess the changes in the ravine ecosystems.
To avoid copyright issues, only the cover pages of these reports will be posted here. All of them can be found in Toronto Public Library.
