Idaho law states that any motorized or non-motorized boat operating in Idaho is required to display an Invasive Species Fund (ISF) sticker. When you purchase and display an ISF sticker, you contribute to a fund that provides vessel inspections, washing stations and informational materials that will assist Idaho with preventing the introduction of aquatic invasive species like quagga mussels.
Invasive species are harmful, non-native plants, animals, and pathogens that damage our economy and environments. Invasive species can move into and dominate both natural and managed systems by disrupting the ability of those systems to function sustainably. They are highly competitive, persistent, and can create monocultures that will eliminate Idaho’s diverse biological landscape—a landscape that nurtures Idahoan interests from our recreational pursuits to our ability to help feed the nation.
