An Introduction to Chautauqua Lake’s Invasive Aquatic Plant Species

Click to download event flyer.

There are many aquatic plants living in Chautauqua Lake; Some of these are beneficial native species, while others are introduced species which can have negative repercussions on recreational, environmental, and economic aspects of the lake. A series of free public programs are being offered to help people learn how to differentiate between plant types and learn what we as individuals and as a community can do to prevent the spread of invasive species in Chautauqua Lake.

Early identification of target species, combined with quick, focused actions, can prevent an outbreak from becoming unmanageable. These free programs focus on public education and the future development of an effective Early Detection Volunteer Taskforce. By providing easy-to-use educational materials and offering both basic informational and in-depth training sessions that are concentrated on the priority invasive species most likely to impact Chautauqua Lake in the near future, interested volunteers, homeowners, recreational lake users, professionals, and anyone who is interested can become part of an early detection monitoring network and contribute to improving the health and sustainability of Chautauqua Lake.
