The Humber Arboretum Ambassadors

Arb Ambassadors are the student face of the Humber Arboretum's community engagement activities. Current students of Humber College or the University of Guelph-Humber, they take part in a service learning experience that helps connect their peers and the wider community with the exciting 100 hectare (nearly 250 acre) urban greenspace at Humber College's North Campus. 

The Humber Arboretum Ambassadors is the second level in the Humber Arboretum's Learning by Leading™ program. Students must first complete a semester as an Ambassador-in-Training.

Ambassadors from 2018/2019 facilitated "Building Biodiversity", a free workshop which was supported by a World Wildlife Fund Canada Go Wild at School grant.

What Does an Arb Ambassador Do?

After successfully completing a learning semester as an Ambassador-in-Training, Arb Ambassadors are knowledgeable about the Humber Arboretum, local ecosystems, the connections between nature and wellness, and much more. Drawing on this knowledge, they work as a team under the leadership of a staff mentor and several advanced Learning by LeadingTM students to pitch, plan, and facilitate events and activities designed to share their knowledge and connect more people with the Humber Arboretum.

Examples of past activities include:

  • Hosting a touch table and info booth inside residence to introduce students to the nature in their backyard
  • Running a virtual student coffee house in honour of Earth Month
  • Greeting and checking-in attendees at gardening workshops run by the Arboretum's partners
  • Promoting and taking part in tree planting and other stewardship events at the Arboretum
  • Facilitating a "Building Biodiversity" workshop where the community learned about local bat species, built bat boxes, and added plants to the Tranquility Bird Garden

Ambassadors are also invited to propose individual or small group projects based on their own skills and interests. For example, students with experience in video, photography, or graphic design will have the opportunity to connect with communications staff at the Arboretum to work on creative projects.


Structure and Time Commitment

  • Ambassadors meet for 1-2 hours at a set time most weeks
    • The group meeting time is often used for idea generation and actively working on projects
    • Some weeks the meeting time will be used for mandatory advanced training
  • Events that the group plans may take place on evenings or weekends
  • Ambassadors should expect to commit to an average of 2-3 hours per week
  • The Ambassadors are active in the fall and winter semesters

What is a Co-Curricular Record?

Provided to students by Humber College or the University of Guelph-Humber, the Co-Curricular Record (CCR) is a formal record of a student's skill development that has taken place outside of the classroom.
