Weekend Visitor Center Information Specialists

Help keep the Visitor Center open on weekends by becoming a volunteer! We are looking for people who can take on 1-2 weekends per month. For more information, email Heather.

Volunteering at the Arboretum

Volunteers contribute substantially in the areas of gardening, special event staffing, Visitor Center staffing, tour guiding, surveying, database maintenance, trail education, 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, where we have the resources to do so!

As a City of Portland park, Hoyt Arboretum complies with the City of Portland standard for all volunteers.  This means that folks will need to apply to be a volunteer within Portland Parks and Recreation and consent to a background check.

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.

Thank you for your interest!
