Welcome to The Arboretum!

Arboretum Open for Walkthrough Access Only Until Further Notice - NO VEHICULAR ACCESS AND NO PARKING ALLOWED.

April 3, 2020. The Ontario government announced the immediate closure of all outdoor recreational amenities, with the exception of greenspaces that are used for walkthrough access. In keeping with this announcement, the University of Guelph Arboretum will now be open only for walkthrough access. Those walking through The Arboretum must maintain a distance of two metres between themselves and others.  There is currently no vehicular access to The Arboretum site.  Our parking lots are closed.

We kindly ask visitors to The Arboretum to respect our site and keep your dogs on a leash at all times.  Please note that Arboretum buildings, disc golf course and parking lots are currently closed.  For up-to-date campus information, visit the U of Guelph COVID-19 page. 

 

The Arboretum, University of Guelph, encompasses 400 acres of plant collections, gardens, walking trails, natural woodlands, wetlands, and meadows. Adjacent to the university's main campus, The Arboretum is free to the public and open dawn until dusk - we welcome you to visit!

Established in 1970, The Arboretum is home to more than 2000 different taxa of woody plants, organized into collections that include a synoptic World of Trees collection, as well as a Native Trees of Ontario collection, and noteworthy collections of Oaks and Beeches, Maples, and Conifers.

With a mandate to support 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 also offer dozens of workshops and other programs aimed at the general public, with the goal of helping to connect people with plants and nature.

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