The City of Seattle along with community organizations are inviting the community to celebrate Seattle’s urban forest with several events throughout the week.  

Our third annual Seattle Forest Week is bookended by two large events. Trees for Seattle will host Arbor Day on October 28 at Jefferson Park. The event includes music, an art installation, kids’ activities, and an opportunity to volunteer in the park, including planting large trees around the playground and parking areas near the Jefferson Park Community Center. On November 4, Green Seattle Partnership will host Green Seattle Day at 16 park locations throughout Seattle to help care for and build healthy forested parks. Volunteers are needed to plant trees, remove weeds, and provide a helping hand to Seattle’s forests on both days.  

Several other free events are available throughout the week for community members to learn about the importance of healthy urban forests, plant native plants, and explore Seattle’s forest. Join us for native plant walks, green space tours, and more! All community members are welcome, and no experience is necessary! Seattle Forest Week events are family friendly and open to all ages. 

“I am thrilled that Seattle Forest Week will help shine light on all the incredible ways our urban forest supports Healthy People, a Thriving Environment, and Strong Community. Seattle’s forests help connect us to nature, protect native species, improve our air quality, mitigate environmental impacts, cultivate wellbeing, and provide essential open space to rejuvenate and recreate”, said AP Diaz, Seattle Parks and Recreation Superintendent.

Volunteers needed! In addition to signing up for restoration events, we’re looking for help in many ways, including bringing snacks, taking photos, helping at the sign-in table, and more. Email to sign up.

Green Seattle Partnership and Trees for Seattle bring together local nonprofits, community members and city partners who support the city’s forest and our communities. The value of this work is immeasurable – communities are working together to restore and grow our local urban forest that helps address critical community issues like urban heat, provides connections to nature in the city, and slows stormwater to reduce the impacts of flooding. Fall is the perfect time for planting trees in Seattle due to our cool, wet winters. We take a week to celebrate the beginning of planting season each fall and explore all that Seattle’s forest can offer us.
