Invasive species are a growing challenge on our landscapes and native ecosystems. What is considered invasive? An invasive species is one that is not native to the area and causes harm to the environment, economy, or to human health. There are many non-native species (e.g. lavender, Norway spruce trees, etc.) that although introduced, do not cause harm as defined above.
An invasive species can take over a native habitat and push out existing species. For example, phragmites can colonize a wetland area and choke out every other species to create a monoculture, reducing the diversity of food and shelter available for native wildlife. Phragmites has also been found to alter the hydrology of a site, leading to drier soils altering the landscape and the ecosystem services. Each invasive species requires a different approach. Significant damage can be done by using the wrong removal method. For example, cutting or mowing spurs additional growth in Japanese knotweed. Knotweed must be injected with herbicide during flowering period between August-September. Need more species specific information?

Report Invasive Species
The Midwest Invasive Species Information Network (MISIN) is a regional effort to develop and provide early detection and response resources for invasive species.

Jackson, Lenawee and Washtenaw County Cooperative Invasive Species Management Area (CISMA)
In order to address invasive species across in the region, a collaborative group of stakeholders from the Jackson, Lenawee and Washtenaw Counties applied for, and received a grant to establish the "Jackson, Lenawee and Washtenaw Cooperative Invasive Species Management Areas (JLW CISMA)". The JLW CISMA wants to prevent, detect, eradicate and control invasive species in the area, create a strategic plan for reducing the threat of invasive species and to provide outreach and educational opportunities for local citizens and stakeholder groups . Currently, the JLW CISMA is focusing their efforts on education and outreach. The organization would also like to coordinate and support partner efforts to survey and develop early detection, response and a strategic eradication plan. If you have any questions or would like more information, please contact the JLW CISMA coordinator, Dr. Shikha Singh at Ph: 517-395-2089, shikha.singh@macd.org
Priority Species
As part of our efforts in the JLW CISMA, we are working to identify invasive species of concern in our county. If you have identified a species of concern, please contact us at megan.deleeuw@macd.org or 734-718-5506. You may also fill out a report directly to the State of Michigan here.
A few species that have been identified:
-Japanese Stiltgrass
-Gypsy Moths
-Purple Loosestrife
-Giant Hogweed
