Long-term Changes in the Biodiversity and Ecological Integrity of Toronto’s Ravines  After reading CBC's Ecological collapse of Toronto's ravine system has begun, (Muriel Draaisma · CBC News · Posted: Nov 04, 2018), I am stunned to discover that native plant animal and insect species are disappearing from our Toronto's ravines. To comprehend that 17% of Toronto's land are dying is a disturbing truth. In the 1977-2017 report, (Eric Davies, Anqi Dong, Catherine Berka, Paul Scrivener, Dale Tayl or, Sandy M SmithFaculty of Forestry, University of Toronto July 2018) important restorative methodologies are proposed, including an increase in ecological connectivity and buffers for biodiversity, to regenerate and reintroduce: seed forecasting and collection, as well as to plant ‘local’ native species and remove invasive species. Bringing the Toronto Ravine Strategy to the forefront of our community is obviously of great importance. Perhaps taking cue from the rapport and expanding our understanding and knowledge of native species, invasive species and our role to seed or remove, might make a difference in the future of this Ecological collapse.
