CONTROL PROJECTS
STRIKE TEAM
​
CWIP is developing a trained team of individuals to serve as a Strike Team for our eight-county area. The Strike Team will visit reported patches of isolated high-priority invasive species, confirm their identification, and remove or treat the patch before it spreads. This early detection and rapid response model will help prevent harmful invasives from establishing in our area!
​
Some species that may be targeted by this Strike Team include Amur cork tree, black swallow-wort, giant knotweed, Dalmatian toadflax, Eurasian marsh thistle, giant hogweed, Japanese hops, non-native wisteria, poison hemlock, porcelain berry, wild chervil, and teasel.
JAPANESE HEDGE PARSLEY
​
In 2020 and 2021, CWIP worked with the Central Wisconsin Environmental Station to control a small population of Japanese hedge parsley. This plant has bur-like seeds that are easily transported along trails. Remember to remove seeds from yourself and pets while hiking to avoid spreading invasive plants like hedge parsley!

FOREST INVASIVE PLANT CONTROL WITH EMMONS CREEK DMAP COOPERATIVE
​
CWIP is working on a grant-funded project (2020-2021) to control forest invasive plants including garlic mustard, buckthorn, honeysuckle, and black locust on private forest lands enrolled in the Emmons Creek Deer Management Assistant Program (DMAP) Landowner Cooperative. To learn more about these kinds of landowner cooperatives, visit the Golden Sands RC&D website.
SPOTTED KNAPWEED
​
Through a partnership with the U.S. Fish & Wildlife Service, CWIP treats spotted knapweed to restore habitat for the federally endangered Karner blue butterfly.

JAPANESE KNOTWEED REMOVAL IN TOMORROW RIVER WATERSHED
​
CWIP is has finished working on a three-year project (2021-2023) to control Japanese knotweed growing along water bodies in the Tomorrow River watershed. Much of the knotweed is located next to the Tomorrow River in the Village of Amherst. Plants were cut multiple times during the growing season and treated with aquatic-approved herbicide in late summer/early fall.

These two images are of japanese knotweed in Amherst at Scout Hall Park. These photos were taken in early summer 2023. The left image is the same location as the images above from 2021 and they look so much better! The knotweed has now been treated in 2021, 2022, and 2023. CWIP's role in this project is complete and the landowners are much better equipped to handle the knotweed now.
