Is there help to get rid of invasive plants? #923237

Asked December 31, 2025, 10:28 PM EST

Hello, I live on the Willamette River at 5605 River Street, West Linn. There is a large area between the back of my home and the river. I am very concerned because of the variety and amount of invasive plants that are thriving. There is bamboo, Japanese knot wood and so many blackberry plants. I would like to remove the invasive plants and replace with native plants. I have contacted the owner of Bosky Dell Natives. She is willing to help me make a plan and give me a discount on native plants. I want to start with a small area and concentrate on that. Currently it seems overwhelming. I am just wondering if there are any grants to help with purchasing native plants or any resources to help eradicate the invasive plants? Since I live close to the river I have been hesitant to use any harsh chemicals, however, I also have not had much success in making a dent on the invasive species either. I am looking for any resources, information or help that may be available. My husband and I are willing to do a lot of work but I feel like the job is bigger than we are. Kind regards, Beckie and Kevin Plaza 5605 River Street West Linn, Oregon 9706<personal data hidden>

Expert Response

Greetings Beckie,


Thank you so much for reaching out and for your care for the land along the Willamette River. The mix of bamboo, Japanese knotweed, and blackberry you’re seeing is very common in this part of West Linn, and it can absolutely feel overwhelming for one household to tackle alone. The good news is that there are several local programs designed specifically to help landowners in your situation, especially those living along waterways.

Below are the most helpful resources available in Clackamas County:

1. Start by connecting with the Clackamas Soil and Water Conservation District. They can help guide you through the other options as well. 

Clackamas Soil & Water Conservation District (SWCD) – WeedWise Program
The WeedWise team provides free support for managing invasive species, including bamboo, knotweed, and blackberry. They can offer site visits, help you prioritize where to start, and recommend safe, effective control methods—especially important near the river.

Additional options: 

Streamside Habitat Assistance (Clackamas SWCD)
Because your property borders the Willamette River, you may qualify for additional streamside habitat support. This can include help developing a restoration plan, selecting native plants, and understanding erosion or water‑quality considerations.

OWEB Small Grant Program (up to $15,000) https://www.oregon.gov/oweb/grants/small-grants/pages/small-grants.aspx
The Oregon Watershed Enhancement Board offers small grants for projects that improve riparian habitat, including invasive removal and native plantings. These grants require a partner organization, and Clackamas SWCD or the Clackamas River Basin Council can help you apply.

Clackamas River Basin Council (CRBC) https://clackamasriver.org/
CRBC supports landowners with project design, grant applications, and habitat restoration. They frequently work with homeowners on invasive removal and native plant establishment.

City of West Linn – Native & Invasive Plant Resources https://westlinnoregon.gov/parksrec/invasive-plants-weeds
The City provides guidance on priority invasive species, safe removal practices, and recommended native plants for your area. While they don’t offer grants, their technical resources are very helpful.


Thank you for being a thoughtful steward of the land. If you would like resources on specific weeds and their management recommendations, feel free to reach back out.
