Join water chestnut removal efforts occurring in the SLELO region. Water chestnut (Trapa natans) is an invasive aquatic plant that grows thick, dense, floating mats that impede aquatic recreation, reduce waterfront property values, and alter aquatic ecosystems. Water chestnut populations can be suppressed through manual removals of their floating rosette and nutlets.

What to Expect: Using a kayak or canoe to paddle around a given area to collect the floating rosettes and nutlets of water chestnut and bring them ashore to be disposed of.

Tips: When removing water chestnut plants, it’s only necessary to take out the leaves and fruits. Since water chestnuts are annuals, the roots will die without leaves, and the plant can’t spread without seeds. Uprooting the entire plant disturbs the sediment at the bottom of the water body, which can alter the shape of rivers and streams and reduce nutrient availability for native aquatic plants.
