Terrestrial Invasives

Removal Workshops

Golden Sands RC&D staff have worked with several high schools in our service area to train the students on identification, removal, and treatment of invasive species.  Partner schools include Wausau East High School, Wisconsin River Academy, and Weyauwega-Freemont High School.  Species targeted in these field trips include non-native honeysuckles, non-native buckthorns, Japanese barberry, and Japanese knotweed.  The hands-on field trips are not only educational for the students, but also work to restore valuable public green spaces.  Parks we've worked on with the students include Fern Island (Wausau), Riverside Park (Wausau), Green Circle Trail (Stevens Point).  
Sponsors and volunteers are needed to support these service learning field trips.  Click our "Get Involved" tab to join the fun!

Our workshops have also helped lake groups and other citizen volunteers to learn how to control invasive species on their property, such as Japanese knotweed, a plant with such tough, aggressive roots it can grow right through housing foundations!  Our proven techniques are effective 
and minimize the use of chemicals, to produce good results while also protecting the surrounding environment. 


Spotted Knapweed Biocontrol
Spotted knapweed (Centaurea stoebe micranthos) is a weed native to Europe that was brought over to the United States in the 1800s.  It is poisonous to other plants (phytotoxic) and is a threatens Wisconsin's native prairies and pasture lands.

Golden Sands RC&D has partnered with Friends of Hartman Creek State Park to release and monitor Spotted Knapweed weevils.  Root boring weevils (Cyphocleonous achates) and seedhead weevils (Larinus minutus/obtusus) were released in the park the summer of 2015.  The weevils' progress will be monitored and as their numbers increase, the park can become a weevil collection site for other landowners and groups looking to control knapweed on their own properties.



Boot Brushes & Interpretive Signage
Thanks to funding from Izaak Walton League, Community Foundation of North Central Wisconsin, and Waupaca Area Community Foundation, Golden Sands RC&D was able to design and fabricate signs alerting trail users to wipe their feet and minimize transportation of seeds.  Boot brushes were also provided by Izaak Walton League.  Signs and brushes have been installed at 8 trail heads in Waupaca and Marathon Counties so far, with plans to install in other counties pending funding.
