Habitat restoration sites on the Duwamish River were once used for industry, but now provide shelter and food for wildlife like salmon. ospreys, great blue herons, and bald eagles. At our events we remove invasive weeds, spread mulch, plant native vegetation, and pick up trash. 

No experience necessary. Children 10 and under must have one-to-one adult supervision.

We’ll be there rain or shine so dress for the weather (rain gear in case of bad weather or sunglasses and a hat if it's sunny). Wear sturdy foot gear (sneakers, hiking boots, etc. No sandals). Long trousers and long sleeves are helpful if there is blackberry.

Bring work gloves and weeding tools if you have them.  Bring a water bottle and lunch.

We will provide work gloves, tools, snacks, and beverages.

Reservations requested so we'll know how many tools and how much snacks and beverages to bring.
