What is green and roughly the size of the city of Paris, France? If you guessed Toronto’s natural areas, you’d be correct. Spanning over 11,000 hectares (or 110 square kilometers), they:
Support the livelihood and wellbeing of over 3 million people
Provide homes for plants and animals
Regulate nutrient and water cycles
Protect us against flooding and erosion
Despite their significance, Toronto’s natural areas are at an ecological tipping point. Invasive species, climate change, overuse, development pressures, and excessive litter threaten the future of the city’s ravines and natural areas.
How Can You Help?
When you join Toronto Nature Stewards (TNS) as a volunteer, you join a community of hundreds of other nature restoration volunteers passionate about building urban ecosystems that are self-sustaining. Spread over 53 public sites, our volunteers remove harmful plants, plant native species, remove trash, and educate others in their community about natural ecosystems.
Let’s work together to ensure that our ravines and natural areas thrive.
Toronto Nature Stewards is hosted by the Institute of Forestry & Conservation in the John H. Daniels Faculty of Architecture, Landscape, and Design
The continuing support of the Smith Urban Forest Health Lab at the Institute of Forestry & Conservation in the John H. Daniels Faculty of Architecture, Landscape, and Design at the University of Toronto is gratefully acknowledged. By providing a home for Toronto Nature Stewards, the Faculty continues to lead by example in building a more sustainable urban future for all of us.
