Wollongong Campus Tree Walk

Wollongong Campus Tree Walk

Wollongong campus is located at the base of Djeera (Mount Keira). You’re invited to look, listen, and learn alongside the native plants, birds and animals to show your respect for Country.

Country is living and breathing, encompassing the land, sky, waterways, plants, animals, and people—all interconnected through spirit, culture, and knowledge.

For countless generations, local Aboriginal people have cared for and continue to connect with Country. All plants hold Aboriginal cultural significance in helping to create tools, medicine, food, ceremony and knowledge.

UOW is now home to a rich variety of native trees and shrubs after planting over 50,000 native plant species since the 1970s, regenerating what was previously cleared farmland plant species since the 1970s, regenerating what was previously cleared farmland.

To begin your journey learning about the trees and animals please enjoy the Campus Tree Walk.

Navigating the walk

There are 50 trees on the Campus Tree Walk.

Open the Campus Tree Walk in Google Maps on your device to find your way between trees on the walk or download and use the Campus Tree Walk map (PDF).

Each tree has a sign sharing information about the tree’s story and relationships and there is additional information about each tree on this webpage. The Campus Tree Walk will take approximately 60 minutes at a relaxed pace to wander around read the sign, explore the additional information on the webpage and move to the next tree.

Please do the walk in this way if you wish. However, we would like to invite you to consider interacting with the trees and the campus tree walk via a two-way knowledge approach which will take much more time.

Call to care

Having a physical sign at each tree (and information on this webpage) is very much a western approach to learning and sharing information.  From an Aboriginal viewpoint the trees do not need a physical sign because the tree itself is the sign and much more. By taking time to look, listen and observe you learn who and what the tree is and its connection and relationship with other plants and animals (including yourself), as well as connections and relationships with things like the water, climate and soil. 

Please use the information on the signs and this webpage as an invitation for deeper engagement with each tree and to learn from the tree itself. This kind of learning requires time and patience. By using this approach, we will begin to understand the tree and its relationships and its roles and responsibilities. In turn, this helps us to understand our roles and responsibilities to the tree, helping us to think of ways that we as humans can protect and care. 

Learn about the trees

Explore the Campus Tree Walk and deepen your relationship with the trees around you. Broaden your understanding of the many interconnected relationships that exist between plants, people, animals, land, water, air, climate and seasons.

The information about the Campus Tree Walk on this webpage is a work in progress and will be updated and expanded over time.
