Parrotfeather Milfoil - ISDA Aquatic Noxious Weed Program

The Idaho State Department of Agriculture coordinates a statewide aquatic invasive species management and control program, acting to protect the integrity of the state’s water bodies from the biological degradation caused by aquatic weeds.

By achieving this goal, the economic, recreational and aesthetic uses of water bodies are protected, water quality is maintained, and natural aquatic systems are not impaired.
