The Aquatic Invasive Starry Stonewort
Starry stonewort plant and reproductive bulbil
The Geneva Lake Environmental Agency would like to thank all the Geneva Lake lovers that contributed to our starry stonewort management. Although things are now a bit different than a year ago, managing invasive plants is still a priority for the Geneva Lake Environmental Agency. Money raised through Go-Fund Me will be used for starry stonewort and aquatic invasive species control.
Starry stonewort became a serious concern during the fall of 2018 when it was found in a lagoon located in the southeastern shore of Geneva Lake. During the summer of 2019 two small patches of starry stonewort were found in the lake near the lagoon.
The present starry stonewort management strategy on Geneva Lake is to contain and control the spread of starry stonewort to other locations within Geneva Lake. Major components of that management effort are:
- Eduction, working with the Clean Boats Clean Waters program,
boaters and lake user will be informed of the efforts they need to take to help reduce the spread of aquatic invasive species.
- Monitoring, conducting lake-wide aquatic plant surveys to see aquatic plants and their density in the lake.
- Protection, maintaining a healthy lake plant community to protect against the establishment of non-native species.
The GLEA will be conducting a lake-wide point intersect (PI) aquatic plant survey during the summer of 2020 and 2021. The surveys will monitor the health of the aquatic plant community. Education of boaters to clean their boats, trailer, bilges, bait buckets, live wells and anchors as they move between lakes as well as within Geneva Lake is vital in controlling the spread of aquatic invasive species. The GLEA is exploring the possibility of establishing cleaning stations at the municipal launches for cleaning boats before and after boating on Geneva Lake. During the summer of 2020 the GLEA will staff the muncipal launch sites with individuals trained in the Clean Boat Clean Waters program to work with boaters on understanding their obligation in reducing the spread of invasive species.
It is illegal to leave a launch site with vegetation hanging on your vehicle, boat or trailer. You will not be allowed to launch on Geneva Lake if you do not follow the required boat cleaning before you launch. See the Wisconsin Department of Natural Resources web site ( https://dnr.wi.gov/topic/Invasives/boat.html)
for information on boat transportation and bait laws.
