Conservation Projects

Conservation Projects at RBG

RBG’s conservation efforts occur in forest, wetland and prairie habitats and range from species at risk inventories to invasive alien species management.

In additions to our display gardens and horticultural conservation work, Royal Botanical Gardens works hard to preserve and restore its nature sanctuaries. This includes Project Paradise —one of the largest freshwater restoration projects of its kind in North America— that works to restore aquatic habitats of Cootes Paradise and Grindstone Creek marshes.
