Planting in November Along the Boise River at Marianne Williams Park

Saturday November 12 the cold weather did not stop a crew of some 40 volunteers to complete a major planting along the Boise River at Marianne Williams Park. The early November snow? No problem.

Under the leadership of TU volunteer coordinators Trevor Sheehan and Richard Jones, Trout Unlimited took on an important planting of three plots along the Boise River, in coordination with the City of Boise and the Boise Golden Eagle Audubon Society ReWild project. We were also joined by a number of Timberline High School students, members of the TREE Club.

The plantings will help restore a Boise River riparian area next to Marianne Williams Park. Saturday’s work was putting in native plants and trees. And another big part of the work that morning was beginning the repair of a damaged section of the river bank fencing it from public use and future erosion.

“I would like to thank each and every one of you who bundled up, got out in the snow, and helped out with planting at Marianne Williams Park,” said coordinator Sheehan. “It means a lot to me that you would spend your Saturday morning playing in the dirt with me. Kristen from the city was VERY happy with the work we did.”

Next spring and summer will be a critical time for these new plants to get established. Something that will help is a bit of extra water, and in the future there will be lots of volunteer opportunities for you to help with that. The soil will be pretty well saturated through the winter and spring, but when the hot and days come along the plants could use a bit of help with a deep watering. Particularly the plants in sandier soil like the area we fenced off. Feel free to reach out with any questions or comments.

Once again, thank you all! That was a great time and I hope you had fun too.

Sept 24 Project

The weather is helping us out and now is the time to do some stream restoration work. 

We have a project on Warm Springs Creek here in Boise. We have previously had several work activities at this site. So joining us for these projects will allow you to see the fruits of our/your labor on previous efforts.

September 24th, this coming Saturday. 

    We will be weeding around the trees and willow we planted last winter and early spring. There is a significant amount of reed canary grass and purple loostrife and these invasive plants need control. Some work tools will be provided. But it is likely we will do a lot of hand pulling.

    Time Line:   Starts at 10 AM and will last about 2 hours. If you have them please wear waterproof boots. the area along the stream is fairly muddy.

Where to park and where to work.

Sept. 20 Volunteer Event

Volunteer event number 3 at Marianne Williams Park:

Tuesday, September 20th from 5:30pm to 7:30pm

We would love some help pulling noxious weeds, wrapping trees to mitigate beaver damage, closing unnecessary social trails and picking up trash along the river bank at the park. The more volunteers we have, the more of these goals we will work towards. We will be meeting in the parking lot at 5:30 on September 20th.

This is the first volunteer event we’ve had in the evening, and we would love to see you there!

Bring your fly rod for some evening fishing following the event if you’d like. Email if you have any questions or to RSVP.

Stewarding the Riparian

Our June 4 project at Marianne Williams Park is our initial foray into working along the riparian area of the Boise River at this park to improve the natural vegetation.

A rainy day met our volunteer crew – which was nice! We were able to pull weeds in several areas on a day that was not too hot for outdoor work. Here are some photos:

We plan to do quarterly volunteer projects at this site in cooperation with Boise Parks and Recreation.

June 4 Volunteer Project

The Ted Trueblood Chapter has signed an agreement with the City of Boise thru their Adopt-A-Habitat program. We are sponsoring 13.5 acres of river front riparian ground located between Mary Anne Williams Park and the Boise River in east Boise. 

We will have three to four volunteer projects per year at this site. It’s in Boise so you will have easy access to the projects and a city park restroom. Parking is beside the Greenbelt so if you choose to you can take a walk before or after the volunteer project. We encourage you to bring your kids to join us for these conservation projects.

Our first project is on June 4th starting at 9 am running to about noon.

We will be removing noxious weeds including Houndstongue (Cynoglossum officinale) and Spotted knapweed (Centaurea stoebe),  wrapping (or rewrapping) cottonwoods for beaver protection and potentially closing some unnecessary social trails. 

We also will clean up trash as we work to remove the noxious weeds. 

The city will provide needed tools and materials. Just dress appropriately for the weather, grab some gloves, sunblock, a bottle of water and join us for our first project at our sponsored site along the Boise River.

To volunteer email Richard Jones at

Thank you for your time and we hope to see you on June 4th!

Work at Warm Springs Creek

The Ted Trueblood Chapter is working with the Harris Ranch Wildlife Mitigation Association on restoring aquatic habitat at Warm Springs Creek, a tiny tributary to the Boise River in east Boise. Our most recent work was organized with One Stone students who helped dig down the stream channel to make it possible to do the planting of cottonwood tree cuttings in the photo above, taken during the work session on Saturday March 19.

Earlier in the winter we had work crews with Riverstone School help dig out the inner channel and place the biologs to define the channel so that willow and cottonwood can be planted to eventually provide shade to this section of stream.

We soaked the cottonwood trees in the creek for a day prior to the planting effort on the 19th.
