Tree Stewardship Projects

Tree Stewardship volunteers care for trees in public landscapes across Seattle. Tree Stewardship projects engage volunteers removing ivy and other aggressive weeds that damage our forest. Volunteers also lay mulch and take on other tasks that keep trees healthy. 

Trees for Seattle staff organize events and provide tools, gloves, snacks, and help. Learn more about where we work or find an event near you.

We hold at least 1-2 work parties a month. Work parties are a fun way to meet your neighbors and do some good for our urban forest. Check out our events calendar and join the fun!

Do you have a group of 10-30 people who would like to work together to care for Seattle's trees? Contact us about bringing your group to a work party by emailing treeambassador@seattle.gov.

Success Stories

Tree Ambassador volunteers accomplish a lot! Check out some of the before and after photos below to learn more about the type of work our volunteers do every month.

Phinney Ridge Triangle (50th & Phinney Ave)

Since Tree Ambassador Terrence adopted this site, volunteers have accomplished so much! Neighborhood volunteers helped remove aggressive weeds like blackberry and ivy, improve sightlines for drivers and bikers, and plant new native sword ferns.

Before- Spring 2016

After- Winter 2017

Hillman City Triangle (Rainier Ave & Graham)

Tree Ambassadors Demetria and Dave have helped give this Hillman City triangle a huge makeover since they adopted the site. Volunteers have focused on helping the large mature Japapanese black pines by removing the aggressive English ivy and blackberry growing around them. Since starting their work, this site has less garbage and sightlines have been improved for the pedestrians who use the bus stop.

Before- August 2016

After- September 2016

Ravenna Traffic Bulbs (52nd & 22nd Ave)

Tree Ambassador Sharon has given these Ravenna traffic bulbs a complete makeover, including removing the aggressive ivy taking over the trees, mulching, and replanting with drought tolerant natives.

Before- June 2014

After- December 2015
