Water chestnut (Trapa natans) is an aquatic plant native to Asia. In the Americas, water chestnut is an invasive species known for its aggressive growth habits.
One acre of water chestnut can produce enough seeds to cover 100 acres the following year. With four, hard half-inch spines that are sharp enough to penetrate shoe leather and large enough to keep people off beaches, these seeds are major hazards to water contact recreation. Additionally, water chestnut can wipe out native bay grasses from some areas, prevents nearly all water use where it occurs, creates breeding grounds for mosquitoes, and provides only marginal habitat to native fish and birds.
