Help treat and remove a variety of invasive plant species at Cartier Park. A discussion to identify these plants will take place before we begin. AFFEW partners with the City of Ludington, Mason-Lake Conservation District and North Country CISMA to remove/treat these aggressive plants. Below is more information on some of the challenging invasive plants at Cartier Park.
Check the schedule on our Events and Activities page for dates we’ll be meeting. Meet by the gazebo along Lincoln Lake at the end of Rath Ave. Bring water, gloves and wear long pants, long sleeved shirt and closed toed shoes. Event will be held in fair weather, and sometimes wraps up early, depending on site conditions. Please note: both September events will be at 10 am. To be added to our email list to receive reminders about upcoming events and cancellations due to weather, contact Sara Bolan at sarab@affew.org or by phone 815-592-9032.

Unfortunately some of these invasive species can still be bought at nurseries and big box stores. When considering plants for your property choose native species over invasive. Once an invasive plant escapes into a natural area it can cause significant issues for native plants and wildlife. This includes altering soil chemistry in a way that gives future generations of invasive plants a competitive advantage.
Below is information compiled by Dave Dister, local botanist and author of The Birds of Mason County, Michigan, regarding invasive species he has identified at Cartier Park and his extensive research on the “Vascular Flora of Ludington State Park”. He’s also provided additional resources you may find interesting.

The North Country CISMA and AFFEW will host a walking tour in Cartier Park, and focus on identification of invasive plant species, recommended treatment methods and the benefits to native plant species. Participants will be able to partake in hands-on identification of plants, view past treatment areas and a native wildflower demonstration garden. Please bring a mask and plan on maintaining an appropriate distance from others on the tour. Those interested in joining are invited to bring a bag lunch and stick around after the walk for a dispersed picnic lunch (likely on the lawn around the gazebo!) and further discussion on invasives. Meet at the dog park by at the end of Rath Ave. Event will be held in fair weather, and sometimes wraps up early, depending on site conditions.
