Removing European Frogbitfrom Shelburne Pond
A Site-Specific Guide
The Lewis Creek Association will help to determine a designated location to store harvested frogbit at
Shelburne Pond. The identified site will have minimal drainage and be situated at least 20 feet above the
high water mark. Please remember that it is illegal to transport invasive species in Vermont. See the Lewis
Creek Association’s Best Management Practices about composting and safe removal methods.
European frogbit must be hand-
pulled from infested sites. The most
effective way to do this is with
canoes, kayaks, or chest waders.
Frogbit is pulled from the site and
put into 5-gallon buckets with holes
drilled in the bottom, or plastic mesh
laundry baskets. Laundry baskets
can be affixed to kayaks using
bungee cords, and 5-gallon buckets
can be stored in canoes while
picking. Chest waders should only beused in shallow locations and
harvested frogbit should be stored in
boats.
Due to thick vegetation, some areas
of the pond are inaccessible. It is
recommended to clear open waters of
frogbit first, and then attempt to clear
~10 feet into the vegetation (cattails,
bulrushes, sedges, etc).
Due to the large size of the ShelburnePond, it may be useful to utilize a
motorboat to store collected frogbit
in to increase harvesting efficiency.
Frogbit reproduces around mid-
August. Harvesting plants after this
point is ineffective. The
recommended frogbit removal season
is June and July.
