We've been a nonprofit in Portland since 1996! Our mission is: to protect and enhance the Columbia Slough and its watershed through community engagement, education, and restoration. We provide over 300 free education programs to Title I schools every year, we plant over 10,000 native plants a year, and we get hundreds of people out on the water in canoes and kayaks for free!
