Carolinian Zone

The Carolinian Zone in southern Ontario is a hotspot for biodiversity, with more species of rare plants and animals than anywhere else in Canada, including the Blanding’s turtle, southern flying squirrel, rusty-patched bumblebee and monarch butterfly.

Not only is the Carolinian Zone home to one-third of Canada’s at-risk plants and animals, it’s also home to a quarter of our human population, including many Indigenous communities. With the region’s population projected to grow significantly, so will its impact on nature and the health of wildlife, which can make landscape planning, management and balancing our ways of life with healthy ecosystems challenging.

That’s why, if you live in the Carolinian Zone, your garden is a critical piece for restoring lost habitat and creating a healthy future for the region and the wildlife that call it home. Please join us in making your garden part of the solution — together we can grow life-sustaining habitats and resilient landscapes, one yard at a time.
