Corporate or Group Volunteering

Volunteering is a great way to help teams learn more about one another, build camaraderie, and become better community members. There is always a place for your team or group to learn, play, and work up at Hoyt Arboretum!

If you're interested in a group volunteer opportunity, please email us at with your group size, preferred dates or date range, and length of shift you'd prefer. We'll get back to you as soon as possible with some options or ideas. Thursdays and Fridays usually work best. Your group is also welcome to join our Saturday Crew or one of our special volunteer events (E.g., Arbor Day, Earth Day). Check our upcoming events page for more details. 

Volunteering at Hoyt Arboretum

Volunteers contribute substantially in the areas of gardening, special events and outreach, visitor services, tour guiding, citizen science, database maintenance, photography, research, trail and tree maintenance, trail roving and more!

Throughout the year, volunteer opportunities will be available at the arboretum working on events, greeting the public at the Visitor Center or joining a work party to make improvements on the trails and collections. We are also happy to work with special school projects or individual projects of interest.

As a City of Portland park, Hoyt Arboretum complies with the City of Portland standard for all ongoing volunteers. This means that potential volunteers will need to apply to be a volunteer within Portland Parks & Recreation and consent to a background check. This doesn't apply to Saturday Crew, Tuesday Crew drop-ins, or specially scheduled work parties.

We rely on, and very much appreciate, the support we receive from our team of volunteers. If you are interested in volunteering, just fill in the form below and we'll be in touch with you.
