Aquatic Invasive Species: Hydrilla

Apr 27

Posted by

Hydrilla, native to Africa, has become a widespread invasive aquatic plant in U.S. waters. It forms dense mats that interfere with recreation and harm fish and wildlife habitats. Hydrilla spreads easily via seeds and fragments, making control challenging.

Management methods include:

  • Biological: Grass carp consume hydrilla but may also eat native plants.

  • Chemical: Herbicides are effective but can cause oxygen depletion and resistance.

  • Physical: Hand pulling, drawdowns, and aeration are labor-intensive.

  • Mechanical: Aquatic weed harvesters cut and remove hydrilla, providing immediate, environmentally friendly results while preventing nutrient buildup.
