​Nature Preserves 

The forests, wetlands, meadows and valley lands of the Lake Simcoe watershed are home to thousands of birds, animals and plants.

Our Nature Preserves, also known as Ecological Preserves or Natural Heritage Areas, are conservation properties that we have acquired through purchase or donation. These properties have outstanding natural heritage value and make significant contributions ​to water quality, wildlife habitat, and carbon sequestration and storage. 

While our conservation areas provide opportunities to connect with nature, our preserves help protect sensitive ecosystems in the Lake Simcoe watershed​. Our nature preserves are particularly vulnerable to disturbance, and because of this vulnerability, these properties are not available for public use

Our Nature Preserves 

We currently own or manage 12 nature preserves in​ the Lake Simcoe watershed. We’ve included some of our properties in the list below. Click each property to learn about the habitat and species we’re protecting!
