Japanese Knotweed

Japanese Knotweed is an aggressive invasive plant that is rapidly gaining a foothold in New London and the Pleasant Lake Watershed.  Although not an aquatic weed, the spread of this plant could impact the natural habitat and erosion resistance qualities around Pleasant Lake.

Therefore, watershed residents are encouraged to learn to identify this plant and to consider the implications of allowing this plant to thrive and spread.
