Aquatic invasive species (AIS) are a serious threat to Door County’s waterways and wetlands. Whether they are moved in ballast water, recreational boats, or in the water of a livewell or bait bucket, many non-native animals such as the spiny waterflea continue to spread throughout Wisconsin and the Midwest. These animals can cause severe damage to local ecosystems, industry and tourism. In addition, invasive aquatic plants are one of the greatest threats to the long-term health of our wetlands. Reed canary grass currently dominates almost half a million of Wisconsin’s wetland acres and Phragmites has been expanding westward through Wisconsin from the Lake Michigan shoreline. DCIST has created the following list of aquatic plants and animals that threaten Door County’s natural environments and economy. A summary of the “Top 15” Invasive Plants in Door County (with pictures) can be found at the bottom of this page.
