Upcoming Events

 Thank YOU for a great Duwamish Alive!  Earth Day  April 20th  10 – 2

What a great day celebrating Seattle’s only RIVER, the Duwamish with hundreds of community volunteers working on the river removing debris,  caring for salmon habitat and our upland forests — even a 10,000 year old bog!   In an effort to promote awareness about it, and coordinate efforts to improve and enhance native habitat health and water quality so that people and wildlife can thrive in our urban community.

Our forested areas such as the Duwamish Greenbelt, one of the largest in the lower section of the river, provide important air and water filtration of pollution, especially storm runoff one of the major sources polluting our waters. Tree canopy cover also reduces our summer heat domes, unequally affecting low income, communities of color to a greater degree. Duwamish Alive Coalition continues to nurture and expand tree canopy within our local communities which suffer the effects of pollution and heat domes.

The river ecosystem supports 5 salmon species including the threatened Chinook salmon which is a critical food source for our Southern Orcas; along with wildlife that includes river otters, beavers, bald eagles, and blue herons. Each of our habitat sites supports this web of life while providing important environmental benefits to our communities.

Make Earth Day Every Day  Caring for our lands and waters through simple daily choices makes a difference.  Volunteering throughout the year makes a difference.  Advocating for a healthier environment makes a difference.  Our partners work throughout the year to improve the environment health of our region and its communities.  Please check out their websites for opportunities to get involved.

THANK YOU to all our partners who helped organize the event and the amazing volunteers who helped care for these special places:

Duwamish Hill Preserve, Tukwila    Green Tukwila Partnership  

Duwamish Hill is a sacred site of the Duwamish Tribe, we are honored to help in stewarding this special area by planting native plants in the forest and creation of a new pollinator meadow.  Efforts also include removing invasive plants, soil improvement and mulching.  Also included are special speakers and the launch of the Geocache Adventure Tukwila Legacy Trail.

North Wind’s Weir  Green Line, Tukwila  with Seattle City Light

This site’s entrance is through Cecil Moses Park, along the banks of the Duwamish River in a community led effort to restore habitat.  Volunteers are needed to help protect new plantings from the expected dry, hot summer this year with mulching.  This location is part of the Duwamish Tribal Sacred Place.  For registration email:  info@duwamishalive.org

Cecil Moses Park,  Tukwila    King County Parks    

Cecil Moses Park is located along the west bank of North Wind’s Weir. in the critical transition zone for young salmon moving downstream to Puget Sound with an extensive tidal mixing of fresh and salt waters which allows the young salmon to adapt from the fresh water of the Green-Duwamish River to the salt water of Puget Sound.. Work continues to improve the habitat quality of this important area by removing invasive plants, replacing them with native plants and mulching.

We are honored to help in stewarding this sacred place of the Duwamish Tribe, which is referred to in their Epic of the Winds story.

Point Rediscovery at Hamm Creek, Seattle    DIRT Corps  

Hamm Creek is only one of the two salmon spawning creeks of the Duwamish River and also were John Beal, the first person who started the effort in restoring the river.  John was a veteran of the Vietnam War, who came back with many health challenges and the prognosis of only having 6 months to live. With those 6 months he decided to clean up Hamm Creek, the place of his home.  As the health of the creek improved, so did John’s and his advocacy efforts for the river.  The river we have today is from his initial efforts and all those who have followed in his foot steps.  Point Rediscovery is John’s memorial to his military friends from the war and also to the creek he loved.  Join DIRT Corps in restoring this special place.  Volunteers will be removing invasive plants and debris and providing information on the site itself, how it’s being used to capture and filter storm water, and what needs to happen to make this a salmon bearing creek again. (This site isn’t suitable for young children.)

Roxhill Bog at Roxhill Park, Seattle     Green Seattle Partnership/Seattle Parks

Roxhill Bog is the last remaining peat bog in Seattle of 26 and is ancient remnant of a larger peat fen which started forming 10,000 years ago in this 2,685-acre watershed which once supported large wetland complexes that served as a sponge to filter and cool the waters of Longfellow Creek before they emptied into the Duwamish River. A century of urbanization has extracted the sensitive peat soils and paved and built over critical habitat. Roxhill Bog, headwaters of Longfellow Creek, is the last remaining section of this historic and important ecosystem. Every year salmon still return to the creek but in diminished numbers due to pollution levels in the creek and the remaining wetland areas offer some of the most biodiverse habitat with is being lost due to the drying of the bog and invasive plants.  Work in removing the invasive plants while also preparing the area for summer’s higher temperatures will be focused on for this event.  

Herrings House Park, Seattle     Green Seattle Partnership/Seattle Parks   

Herrings House Park adjoins həʔapus Village Park along the river and provides the largest salmon habitat in the lower part of the river.  This critical area for the juvenile salmon provides them a safe place to rest and forage for food before they enter Puget Sound.  Volunteers will be planting native plants, mulching and removing invasive plants. Also included are special speakers and tabling offering information about the river, its wildlife and efforts to improve its health.

həʔapus Village Park and Shoreline Habitat, Seattle    Port of Seattle & DIRT Corps 

This is a sacred site of the Duwamish Tribe, being an ancestral location of one of the tribe’s Longhouses and located across the street from the Duwamish Longhouse and Cultural Center. We are honored to help in stewarding this special area by planting native plants, removing invasive plants to create a healthy habitat along the river. Also included are special speakers and tabling offering information about the river, its wildlife and efforts to improve its health.

Duwamish Greenbelt at Pigeon Pt , Seattle   Delridge Neighborhood Development  Association     

Upland forests are important part of the river’s ecosystem, providing many benefits to the watershed and communities.  This part of the Greenbelt is also used as an outdoor classroom for local schools.  Volunteers will be planting native plants, removing invasive plants and mulching.

Duwamish Longhouse, Seattle   Duwamish Alive Coalition and Duwamish Tribe  

We are building a special cedar planter at the Longhouse for growing camas, an important plant that tribal members used for various uses including as a food source.  The planter will provide camas bulbs which will be safe source for consumption since the land around the Longhouse has been contaminated by industrial pollution.  The planter will contain soil safe for growing edible plants.   email: info@duwamishalive.org

Duwamish River Kayak Cleanup, Seattle      Puget Soundkeeper Alliance & Heron’s Nest Outdoor Education Center’s  River Access Program

Rescuing Roxhill Bog …. Why it matters, What has been accomplished so far.

As one of the last remaining ancient peat bogs (over 10,000 years old) in Seattle, Roxhill Bog has a unique ecosystem and is the headwaters of Longfellow Creek, which runs 3.5 miles through West Seattle before it reaches Elliot Bay.  Roxhill Bog plays an important part of the creek’s watershed, as the drainage basin for sixty surrounding acres, collecting sediments and pollutants from rain and storm water run off. Plants absorb some pollutants while the spongy peat soil helps filter sediments, essential for providing healthy water quality. Longfellow Creek is one of Seattle’s few salmon spawning creeks.

Climate change and urbanization has impacted the health of Roxhill Bog, reducing the amounts of water flowing into the wetland to maintain its healthy ecosystem.  Water that would normally flow into the bog has been diverted into storm drainage systems while climate change has increased summer temperatures and reduced rainfall causing the peat to dry and degrade.  Visit our Roxhill Bog page for additional information and to get updates on the restoration project.
