Weed Out!

Our parks need you!


Milwaukee County Parks contain most of the county’s remaining natural areas. These valuable areas are seriously threatened by aggressive non-native plants referred to as “invasive weeds.” Invasive weeds can dominate an area so completely that they crowd out native wildflowers, shrubs, and even trees. When the native plants are gone, so are the wildlife that depend on them. Some of the worst invasive weeds affecting our parks include garlic mustard, dame’s rocket, buckthorn, honeysuckle, and Japanese Tree Lilac. In fact, many parks’ natural areas are already overrun by one or more of these swift-spreading species. If nothing is done to reverse this trend, the beauty, ecological, and economic health of our park system will be in jeopardy.

Join the Friends of Grant Park each spring and fall as we work to remove invasive weeds that threaten our park’s plant diversity. If you would like to participate, even if only for a portion of the morning,  come prepared to work: we recommend wearing a long sleeve shirt, long pants, socks and sturdy shoes (long pants and socks are good for tick prevention). If you have a pair of sturdy work gloves, bring them along (gloves provided if you don’t have a pair). Teens 15 and over, such as middle school and high school teams are encouraged to participate, as are congregations and businesses. Please let us know in advance if your group wishes to participate.

2021 fall Weed-Out sessions: Sept. 25 and Oct. 9th, 9 – 11 am. Meet at the tennis court parking lot. Oct. 23, 9 – 11 am, meeting area TBA.

Due to the coronavirus, please be safe : Wear a face mask when in close proximity to others, keep a 6 ft. distance from others, and avoid touching your face, eyes, or mouth until you can wash your hands with soapy water or use hand sanitizer.
