CRAFTSBURY – The Craftsbury Conservation Commission (CCC) has revamped its efforts with a new grant to combat a non-native invasive plant species, Japanese Knotweed.
In 2017, the CCC began the Japanese Knotweed Control Project. The purpose of this ongoing project is to demonstrate the variety of ways to eradicate or control the non-native invasive species.
The CCC applied for the grant in February 2024 through the Vermont Watershed Grant Program, and received $4,938 in March 2024. The program operates under the Vermont Agency of Natural Resources.
The project site is located at the outflow from Little Hosmer Pond in Mill Village, Craftsbury. The project is volunteer-based, with 16 names on the volunteer list currently, in addition to the current members of the CCC.
Japanese Knotweed is usually found in wet habitats, along river and stream banks, and in disturbed areas like roadsides and old fields. Knotweed covers miles of shoreline on every major river in the state of Vermont, according to the Agency of Natural Resources.
Knotweed is problematic for native plant species, waterways and insect populations. Knotweed outcompetes and replaces native vegetation, which hurts local insect populations. This impacts the variety of fish, birds and mammals reliant on insects for food.
Rivers and streams also face an increased risk of erosion, as the ground between dense growths of knotweed can rarely support other vegetation. This leaves the bare soil more susceptible to erosion.
Japanese Knotweed is on the Vermont Noxious Weed Quarantine list. It is illegal to purchase, plant, or transport in the state.
Knotweed can be combated through a “multi-faceted” approach according to the Department of Fish & Wildlife. The most effective treatment is a combination of cutting and chemical herbicide. Knotweed can also be prevented by ensuring the entire root system is removed when pulling the plants.
