Tree Ambassador

Tree Stewardship Projects

Tree Stewardship volunteers care for public landscapes in residential neighborhoods across Seattle. Tree Ambassadors adopt a site and organize community work parties to remove aggressive weeds and care for trees that make our neighborhoods greener and healthier.

Each month, we hold at least 1-2 work parties to keep these landscapes looking their best and to protect mature trees from aggressive weeds like English ivy and Himalayan blackberry. 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 at an upcoming work party!

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.

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.
