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.
