Welcome to The Arboretum!

Arboretum grounds are open for walking and other permitted activities. Building facilities remain closed.

The Arboretum encompasses 400 acres adjacent to campus featuring plant collectionsgardenswalking trailsnatural woodlands, wetlands, and meadows. Established in 1970, The Arboretum is home to more than 2000 different taxa of woody plants, in thematic collections such as a synoptic World of TreesNative Trees of Ontario, and noteworthy collections of Oaks, Beeches, Maples, and Conifers.

We connect people with nature and enhance teaching, research, and outreach at the University. The Arboretum is integral to many undergraduate courses, and acts as a 'living laboratory', providing support, expertise, and a wide variety of plants, species, and environments for researchers at all levels. We offer dozens of workshops and public programs annually, and serve as a beautiful venue for special events.

Our strong focus on conservation of woody plants native to Ontario is implemented through long-running initiatives such as the Rare Woody Plants of Ontario program. We archive, in living gene banks, representative specimens of rare and at-risk trees and shrubs of the province. Through our Elm Recovery Project we are breeding a genetically diverse, Ontario-sourced American Elm population that is tolerant of Dutch Elm Disease.
