Our Mission:

"The Arboretum, an integral part of the University of Guelph, has a mandate to promote education, research and outreach."
-- (Arboretum Master Plan, December 2004)

The Arboretum at the University of Guelph is somewhat modeled after the Arnold Arboretum of Harvard University which is 100 years older.

Plantings started in 1971 and are now maturing to produce a beautiful landscape, within which The Arboretum continues to develop specialized gardens, botanical collections, and gene conservation programs. Labels are maintained at the base of all woody plants in the collections that are listed on The Arboretum map.

The Arboretum spans 165 hectares (408 acres) with 8.2 km of signed trails. Observed at The Arboretum are 38 species of mammals, 188 species of birds, 39 species of butterflies, 18 herptiles (reptiles and amphibians) and 1,700 types of trees and shrubs. Almost every tree and shrub indigenous to southern Ontario is growing at The Arboretum.

The Arboretum offers a pleasant stroll or a study of the fabulous diversity in plants. It is a great place for weddings, dinner theatre or memorial services and dedications. The Arboretum offers Docent-led tours as well as naturalist / horticulturist-led tours throughout the year. A wide array of adult and children's educational programs are also offered covering art, botany, gardening and wildlife.

Without the efforts of over 150 volunteer auxiliary members from the City of Guelph, the University, and financial support of hundreds of people, The Arboretum could not be what it is today. The Arboretum is a significant visitor attraction as well as an important amenity for the citizens of Guelph and Ontario.

Plant Family Collections:

Maples, oaks and beeches, serviceberries, crabapples, birches, viburnums, dogwoods, lilacs, rhododendrons, and the conifers (pines, spruces, firs, cedar, junipers and larches) are presented as a more in-depth display of the genera. In these collections, the emphasis is still on species diversity and includes a range of cultivar selection. The map of The Arboretum will orient you to the location of these detailed plant collections.

Horticultural collections:

Roses, lilacs, serviceberry and dwarf conifers display the extent of horticultural plant selection. The rose collection is significant in that no insecticides or fungicides are used to sustain any plants. This allows visitors to consider which roses would manage well in a pesticide free landscape. The dwarf conifers are presented in their natural form and growth rate and the sculptural variation is quite stunning.

Of Interest to Visitors and Naturalists:

The site offers a diversity of meadow and wooded habitats that meet the needs of a great variety of wildlife. Winter visitors might see the tracks of opossum, fox, coyote, meadow vole and cottontail in the central area of The Arboretum.

Spring woodland flowers abound as the songbird migration sweeps through. You can stand on a boardwalk 30 cm above water in the middle of a soft maple swamp and gaze into the clear water to watch fairy shrimp and other aquatic invertebrates.

Here are several of the main features of The Arboretum:

1) The World of Trees is our major botanical collection, with over 400 species of woody plants.
