Invasive Species

Invasive species are harmful, non-native plants, animals and pathogens that damage our economy and environments.  Invasives 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.

Watercraft Inspections

Idaho’s first line of defense against Aquatic Invasive Species

Snake River Quagga Mussel Detection

The presence of invasive quagga mussels was confirmed in the Snake River near Twin Falls in the fall of 2023.

The introduction of quagga mussels poses a major threat to Idaho. This invasive species can quickly spread and clog pipes that deliver water for drinking, energy, agriculture, recreation, and a variety of other uses. Quagga mussels have the potential to destroy our waters and cost Idaho hundreds of millions of dollars in actual and indirect costs. The ISDA implemented a comprehensive treatment strategy in an effort to eradicate the invasive species.

ISDA Invasive Species Program continues to monitor and survey the river to determine the success of the treatment. ISDA is currently implementing a public access closure and mandatory inspection and decontamination of watercraft in certain stretches of the Mid-Snake River. These efforts are a part of a rapid response plan to minimize the potential movement of invasive quagga mussels.
