Five ways school grounds are adapting for a changing climate
School ground greening isn’t just about creating natural spaces for students, it can also help our cities remain resilient in the face of climate change.

Evergreen has been helping transform school grounds across the country for years.
When we first began working in school grounds, it was a way to bring classrooms outside, inspire educators to create lesson plans around nature and get students to experience loose-parts play and connect to their natural environment.
While that is still the case today, transforming school grounds is now recognized as a potential solution to incorporating resilient infrastructure throughout our cities.
The Limestone District School Board (LDSB), an Evergreen partner, in Southeastern Ontario, with 57 schools and 8 education centres, has been taking the opportunity with new projects to integrate practical solutions for naturalization and climate adaptation.
What exactly makes a school ground resilient? We’ve outlined five changes that Evergreen and LDSB apply to school ground greening projects to make them adaptable to the changing climate:
Inadequate drainage results in large puddles and erosion on many school grounds. With the installation of a rain garden comprised of native plants and grasses, a school will gain areas where water can permeate, mitigating flooding not only of the property but also of nearby streams.
Adding to the urban tree canopy, new trees planted on school properties help prevent erosion and provide cleaner air for students.
Mixed Native Species
Planting native species around the school ground means more water absorption compared to grass. Native species also attract more pollinators to the area, adding to the biodiversity. Using a mixed planting pallet also avoids monocultures making the landscape more resilient to the uncertainties of changing conditions.
Mulch was used throughout the school ground as an absorptive landscape material. It suppresses invasive weeds and helps reduce the watering requirements throughout the property.
An integrated shade structure provides a practical use in offering much needed shade/shelter to students and it also provides a framework for climbing plants.
Some of these changes may not seem ground-breaking, but they work together to create a resilient outdoor space for the school and the community.
“I would argue that simply by integrating the `naturalized area` on a school ground we are `adapting to climate change` via increased awareness of the importance of student stewardship,” says Terence Radford, Evergreen Design Consultant for LDSB. “Addressing climate change is everyone’s responsibility and by supporting schools to create naturalized areas and encouraging students to become stewards of them we build awareness and address the root of the issue; ourselves.”
