riparian restoration - knotweed

Every individual that works with us is making a difference to the health of our riparian buffers by allowing our team to check their land for knotweed and take the necessary actions to control it. Forterra would like to work with you to protect your land from knotweed and restore it with native plants. Eligible landowners will receive technical assistance from Forterra or partners to control knotweed at no cost. Our team returns every summer to help participating landowners to control any remaining knotweed on their property, until the weed disappears completely. Native plants are available to all eligible riverfront landowners and those that live on connecting streams. Forterra staff will work with you to design a custom native plant garden and will install it during the winter, under your guidance.
If you are a landowner living along one of the participating riparian buffers, you can be a part of this region-wide effort to restore the health of our critical waterways. Contact by email to learn more or schedule a time for us to meet you and your land. If you have already contacted us – please fill out the permission form to provide Forterra permission to survey, test and monitor knotweed on your property.

restoring the health of our waterways

The health of waterways throughout the region are critical to the health of Puget Sound and the long-term sustainability of our communities – both natural and human. Healthy rivers and streams have an abundance of trees and shrubs growing along their banks. These plants provide shade to cool down the water during summer and hold onto the soil during winter flooding.
By preventing dirt from washing out into the river, plants help keep water clean for all that use it, including people and salmon. In addition, native plants provide flowers for bees, berries for birds, and leaves for insects. Without these plants, the health of the river suffers as well as the wildlife that need it.
To restore our land and protect our waters, Forterra and partners are working with riverfront landowners to stop the spread of knotweed while reintroducing native trees and shrubs to riverbanks. Knotweed is a bamboo-like plant that grows along rivers and streams in Washington. Over 100 years ago, knotweed was brought to the U.S. as a garden plant, but it quickly spread out of control. Knotweed spreads rapidly and is very difficult to remove. Winter floods and beaver activity can move knotweed throughout the region – knot weed can show up anywhere – even if it’s never been found on a property before.
With continued restoration, cedar and Douglas-fir saplings stand a chance in areas once dominated by knotweed; native gardens of sword fern and Oregon grape contribute to healthy riverside habitat and the enjoyment of homeowners; water quality and flood control are improving; and salmon populations are rebounding.

overview

Forterra and partners are working with landowners to stop the spread of knotweed while reintroducing native plants. If you are a landowner living along one of the participating riparian buffers you can be part of this region-wide effort to restore healthy forests along our critical waterways. We may be able to install riverside trees and shrubs using grant funding, and will work collaboratively with you to design a planting plan that meets your needs.
