Hydrilla Spread Across 70% of Florida Watersheds in 40 Years
Hydrilla, an aquatic plant native to Asia and imported for home aquariums, has become a major management problem in Florida. Since entering the state's freshwater systems in the 1950s, it has spread rapidly, covering 70% of Florida's watersheds. The submerged plant forms dense mats near the water surface and spreads through fragments carried between water bodies.
