cedar river

The Cedar River is home to some of the best remaining salmon habitat in the region, including spawning and rearing areas for the largest number of natural-origin Chinook salmon in the watershed to migrate through the Ship Canal and Lake Washington. It is also an essential water source for over a million Seattleites.
The health of Cedar River—and its inhabitants—has been continually threatened by knotweed, an invasive plant that overtakes riverbanks, squeezes out native species and can quickly destroy properties and ecosystems. Beginning in 2010, Forterra, Seattle Public Utilities, and King County Noxious Weed Control Program established Stewardship-in-Action (SIA), a collaborative partnership that engages local community to restore the banks of the Cedar River. Through partnerships with homeowners and volunteers working on public and private lands, SIA has reduced the footprint of invasive knotweeds along the length of the river by 90%, making room for thousands of native trees and shrubs.
In the fall of 2018, after eight years of hard work, restoration efforts finally reached the mouth of the Cedar River at Lake Washington in Renton. With knotweed under control, a future forest is taking root along all 22 miles of the lower Cedar River. This work supports a healthy system that stabilizes banks, casts shade to keep the river cool for salmon, and provides food and shelter for wildlife.
If you are a landowner along the Cedar River, you can be part of this region-wide effort to restore healthy forests along our critical waterways. We are able to install riverside trees and shrubs using grant funding, working collaboratively with you to design a planting plan that meets your needs. Explore the resources to learn more.

GIVING SALMON AND ORCA A FIGHTING CHANCE

Orcas need clean water and salmon to eat if they are going to survive, so habitat restoration for salmon is key in the long-term strategy for orca recovery. In an intricately connected ecosystem, any one decision will impact the entire web of life; knotweed overtaking a river causes orca hundreds of miles away to go hungry. By taking critical steps towards protecting salmon at Cedar River and beyond. Forterra is working for a healthy future for all.
