Brittle naiad

Najas minor

Brittle naiad (Najas minor) is an invasive plant. It is a native of Europe and Western Asia and was first detected in Ohio in 1932.

Najas minor is an annual aquatic submersed plant. Najas minor can form dense, monospecific stands in shallow water that inhibit the growth of native species of aquatic macrophytes and hinder swimming, fishing, boating, and other forms of water contact recreation. It often grows with other submersed aquatics such as southern naiad, pondweed, coontail, and watermilfoil. .
