Duwamish Alive! Planting at the Duwamish Substation

Duwamish Alive collaborates with communities, municipalities, non-profits and businesses within the Duwamish River watershed to preserve and enhance habitat for people and wildlife and improving the health of Puget Sound.  As a Duwamish Alive member organization, EarthCorps supports this vision of creating a River for All.  Hundreds of volunteers will work with Duwamish Alive member organizations to make a huge impact on the health of the Duwamish River Watershed.
EarthCorps and Seattle City Light are joining forces again for the annual Fall Duwamish Alive event at the Duwamish Substation. 

The Basics

We will supply the gloves and tools and will teach you everything you need to know about tool use, safety, forest health, and the importance of the work you will be doing. No prior experience necessary, just come ready to learn something new! This video may give you a better idea of what to expect.

This event is led by the Puget Sound Stewards, who are part of our program that matches enthusiastic and motivated volunteers to nearshore habitat restoration sites in need of longterm stewardship. 

For your safety and comfort please bring:

  • Clothing that can get dirty (because it will!)
  • Long pants and long sleeves (helps protect against prickly plants)
  • Sturdy shoes that can handle some mud (closed toed shoes are required such as work boots, hiking boots, rubber boots, etc. NO sandals, flats, or heels)
  • Rain gear and warm layers (check the weather!)
  • Sack lunch and snacks
  • Full water bottle
The event will happen rain or shine!

What will volunteers be doing at the event?

While the exact tasks at hand vary, our projects focus on improving the forests, shorelines, and parks in our local cities. Healthy and thriving forests and shorelines are vital to our community because they absorb and naturally filter rain water, produce clean oxygen, provide living spaces for wildlife, and create a place for people to connect with the outdoors.
In order to help create healthy forests, the work can include:
  • Removing aggressive weeds (like English Ivy or Himalayan Blackberry)
  • Maintaining areas where these weeds have been removed
  • Planting trees and shrubs during the rainy season (often Oct.-Feb.)


If you are coming as a group, the group leaders are expected to have an active and integral role in our events. Please get in touch with volunteer@earthcorps.org before the event to make sure everything is in order. On the day of the event, make yourself known to the staff (in bright yellow vests) and arrive early in order to meet your group members.

Youth Policy

Youth under the age of 14 must be accompanied by a parent, guardian, or responsible adult. All volunteers between the ages of 14 and 17 that are not with a parent or guardian must bring a filled out Youth Waiver the day of the event.
Youth and school groups are welcome to attend; leaders should contact the Volunteer Team to take care of all necessary preparations.
