Lake Boren Park Restoration Project
February 11, 2012

Today the troops dug Himalayan blackberry roots from the blackberry corridor and removed Bohemian knotweed canes from a site injected with herbicide in the fall of 2010 in Lake Boren Park. Great job, Troops!

The project was lead by Connor, who attends the International School in Bellevue. He's chosen environmental stewardship for his Senior Project. His project focus is on understanding the negative impact of invasive plants on our ecosystem, the ways to restore a healthy balance to the local habitat, and the need for citizen involvement. This is one of several projects with the Weed Warriors.

The map below shows the project area in Lake Boren Park. The corridor marked in red contains the Himalayan Blackberries.

Lots of Himalayan Blackberry! The site before the project.



Below is what the area should look like with native ferns and salal plants.


We found this patch of native Western Sword Fern in the May Creek Open Space.
Unfortunately, invasive plants are present in many areas of the Open Space.

All who enjoy the amenities of our parks, trails and open spaces are the beneficiaries of these volunteer restoration projects, and are welcome to participate in future projects with the Weed Warriors
