Volunteer Training Opportunities

Arboretum Naturalists

Become an Arboretum Naturalist at Hoyt Arboretum! Arboretum Naturalists are volunteer educators who lead field trips for children (grades K-8) to introduce them to the science of trees and Pacific Northwest ecology through fun hands-on activities.

Arboretum Naturalists lead small groups of students on a 90-minute field trip along the arboretum’s trails to inspire curiosity and discovery in the natural world. Field trips are typically scheduled on weekdays between 10am and 1pm. Arboretum Naturalists should be available to volunteer for a minimum of 2 tours per month during the peak field trip season.

No experience is necessary; training is provided. Volunteers with a love of the outdoors and an interest in environmental education are encouraged to apply (all volunteers must pass a background check). Gain valuable experience working with children and teaching environmental education in an outdoor setting.

Both training sessions are now full. For more information or to sign up for future training opportunities, please email volunteer@hoytarboretum.org or call (503) 823-1649. 

Invasive Rubus Community Science Project

New volunteer opportunity! Non-native Rubus (blackberry) is widespread in the Pacific Northwest and causes negative impacts to native habitats. This new community science project, led by Hoyt Arboretum staff, will survey the presence of four non-native Rubus species in select Portland parks and natural areas throughout the city. The research will help with the early detection of a relatively new invader to northern Oregon, Rubus vestitus, and inform invasive Rubus management and control strategies. 

A training session for Invasive Rubus Community Science volunteers is scheduled for Thursday, April 12 from 10-11am. During this training, volunteers will learn to identify the four invasive Rubus species, choose their assigned parks or natural areas, and learn to collect data and record their observations. For more information or to sign up, please email volunteer@hoytarboretum.org or call (503) 823-1649.
