Morgan Arboretum

Morgan Arboretum. The Morgan Arboretum is a 245-hectare forest reserve and living museum of trees located on the western tip of the Island of Montreal. Established in 1945, it is owned and managed by McGill University's Macdonald Campus in Sainte-Anne-de-Bellevue. The arboretum serves as a vital center for silviculture research, conservation biology, and public education, protecting a significant portion of the region's remaining Great Lakes-St. Lawrence forest ecosystem.

History

The land was originally part of a 1799 Crown land grant to the Religious Hospitallers of St. Joseph, who operated a farm and managed the woodlot. In 1926, the property was purchased by philanthropist David Morrice and gifted to McGill University in memory of his brother, Arthur D. Morgan. Formal establishment as an arboretum began in 1945 under the direction of Macdonald College forestry professor Eugene D. Mulholland, with early plantings focused on creating collections for dendrology studies. Throughout the latter half of the 20th century, its role expanded from a teaching woodlot to a protected area for ecological integrity and a public recreational space, reflecting growing societal interest in environmental stewardship.

Geography and ecology

Situated within the Saint Lawrence River valley, the arboretum's terrain includes rolling hills, glacial till plains, and several small streams feeding into the Rivière à l'Orme. It is a representative example of the Great Lakes-St. Lawrence forest region, dominated by mature stands of sugar maple, American beech, and eastern hemlock. The property also contains significant wetlands, old-growth forest sections, and successional fields, supporting diverse fauna including white-tailed deer, red fox, great horned owl, and numerous species of wood warblers. This ecological mosaic is critical for studying climate change impacts on temperate deciduous forest dynamics.

Collections and features

The arboretum's living collections encompass over 230 taxa of hardy trees and shrubs, organized into both taxonomic groupings and special collections. Notable sections include the Conifer Collection, the Maple Collection featuring species from Asia and North America, and the Nut Tree Collection with specimens of shagbark hickory and black walnut. Man-made features include the Pinetum, the Stuart Herb Garden, and an extensive network of trails for cross-country skiing and snowshoeing. The George H. Montgomery Bird Sanctuary within its boundaries is a key site for ornithology and the Christmas Bird Count.

Research and education

The site functions as an outdoor laboratory for McGill University faculties including the Department of Natural Resource Sciences and the Bieler School of Environment. Long-term research projects monitor forest ecology, soil science, wildlife management, and invasive species such as the emerald ash borer. It is a core site for the TreeWatch network and contributes data to global initiatives like FLUXNET. Educational programming serves university students, school groups, and the public through guided tours, workshops on forestry practices, and citizen science events in collaboration with organizations like Bird Studies Canada.

Management and access

Daily management is conducted by the Morgan Arboretum Association in partnership with McGill University's Faculty of Agricultural and Environmental Sciences. Operations are funded through memberships, user fees, and grants from entities such as the Ministère des Forêts, de la Faune et des Parcs. The arboretum is open year-round to members and the public, with access governed by a conservation-focused mandate that permits passive recreation while prohibiting activities like mountain biking and pet access to protect sensitive habitats. It is accessible via Autoroute 40 and public transit routes operated by the Société de transport de Montréal.
