The Morgan Arboretum is a 245-hectare forested reserve, on the McGill University Macdonald Campus in Sainte-Anne-de-Bellevue on the western tip of the Island of Montreal, Quebec, Canada. McGill University acquired the property in 1945, and through the work of Robert Watson and his son, John Watson, the Arboretum has remained a managed, mixed-used area, used for the purpose of conservation, academic study, recreation, and forestry management. Conservation and education are primary features of the Arboretum forest and many workshops and walks on subjects such as wilderness skills, insects, birds and trees are offered. The 'Owl Prowl' which happens after dark is a popular event. More than 180 species of birds have been observed and about a 100 are known to breed within the Arboretum.
It has also been an important recreational facility for the community. It is supported by both McGill and a charity, the Morgan Arboretum Association.
