About Us

The Oak Ridges Moraine Land Trust is a group of citizens and neighbours working together to protect and steward Moraine properties for our collective benefit.

This is Your Land Trust

Our Moraine is crucial and ecologically sensitive land. Consider what just one acre of green space, covered with forest, wetland or open meadow does for you: cleans our air, cleans and regulates our water, shelters wildlife, supports pollination, provides space for recreation, protects us from run-off and erosion, ensures dispersal of seeds, and more.

The task of protecting these vital and important properties is not just for landowners, but for all our neighbours who enjoy these natural, public benefits. That’s you, me and all of us. What will you do to raise your voice for our Moraine?

Lands protected today grow in importance as open spaces decrease. Because of caring donors like you, water will continue to be cleaned, trees and shrubs planted today will grow and spread and clean more air, shelter more birds and wildlife and provide more green space for everyone to enjoy.

Our team would love to hear from you if you have questions or ideas, if you would like to join our mailing list or request information, or if you are inspired to get involved.
