The Arboretum features a unique collection of trees specifically gathered from different regions of the world for comparison.
It contains four distinct Gosling Wildlife Gardens designed to demonstrate how homeowners can attract birds, butterflies, and other pollinators.
The site includes a significant collection of rare and endangered woody plants native to Canada.
It houses a dedicated herbarium collection used for academic research into plant taxonomy.
The grounds feature a specialized 'tree improvement' program focused on the genetic health and resilience of Ontario's native forests.
The property acts as a major migratory stopover point for various bird species due to its diverse food sources and protected habitats.
The Arboretum at the University of Guelph spans 165 hectares and serves as a living laboratory featuring over 1,700 woody plant taxa. Established in 1970, the grounds include natural woodlands, wetlands, and curated horticultural collections arranged by taxonomic and ecological groupings. Key features include the World of Trees trail, which highlights diverse international species, and the specialized Gosling Wildlife Gardens. The site functions as a research and conservation center while providing a public space for environmental education. It contains extensive collections of native Ontario tree species, including mature stands of oak, maple, and coniferous varieties. Visitors access these diverse micro-habitats via a network of maintained trails that weave through varying terrains. The area is integrated into the broader University of Guelph campus landscape but maintains a distinct botanical focus. Its primary mission involves the documentation and preservation of diverse plant species within a controlled yet accessible natural environment.

Bring insect repellent during the summer months, as the wetlands and wooded areas can have high mosquito activity.
Pick up a printed trail map at the Arboretum Centre entrance to help navigate the extensive, sometimes unmarked, woodland paths.
Check the event calendar for seasonal guided workshops or tree identification tours before visiting.
Do not collect seeds, berries, or plant cuttings, as these are managed for scientific study and ecological health.
Grounds are open year-round, though some secondary trails may be unmaintained or icy during deep winter months.
Stay on marked trails to protect sensitive root systems and rare plant specimens; pets must be kept on a leash at all times.
