Water Chestnut: Alien Invader
Water chestnut is an aquatic invasive plant from Europe. It lives in shallow water, dropping spiky nutlets into the mud that grow into new water chestnuts. The nutlet acts as an anchor with a long stem leading to a floating circle of leaves at the surface.
Water chestnut has been in North American since the 1860’s, when it was found in Massachusetts. Since then it has spread to many areas of the Northeast. Big Pond at Audubon has been trying to combat the aquatic invasive species for the past seven years.
