The primary purpose of the Idaho State Department of Agriculture's (ISDA's) noxious weed cost share grant program is to accelerate the attack on invasive weeds by supplementing local funds and resources, not replacing them. Cost sharing is also intended to provide additional incentives for local landowners, officials, and citizens to work collaboratively to develop a more comprehensive and effective noxious weed management program.

Anyone who will launch a boat in Idaho waters must buy an Idaho Invasive Species Fund sticker from Idaho Parks and Recreation, The fees generated from the sale of these stickers will fund vessel inspections, washing stations, and informational materials that will help Idaho prevent the introduction of aquatic invasive species, such as quagga mussels.

If you plan to use your own boat or angler float tube, you’ll need a permit and a free Yellowstone aquatic invasive species inspection. You can speed up the inspection process by arriving with a boat that is clean, drained, and dry. Watercraft that arrive dirty or with standing water will be subject to decontamination. Watercraft that cannot be properly decontaminated will be prohibited from launching.

Idaho watercraft inspectors have identified zebra mussels on a commercially hauled sailboat destined for Lake Coeur d’Alene in the state’s northern panhandle, marking the first time the invasive species has been found live this year.

It is important to stop new outbreaks before they start. You can protect Idaho from invasive species by taking action. By the time an invader is readily noticeable and begins to cause damage, it is often too late, resulting in an expensive removal of the established invader. If we detect new outbreaks early and act quickly to control them, we can avoid many of the environmental and economic losses caused by invasive species.

The Idaho Department of Agriculture (ISDA) has confirmed the presence of quagga mussel in the Mid-Snake River. Quagga mussel larvae was first detected in the Snake River near Twin Falls on September 18, 2023, by routine monitoring conducted by the ISDA. If nothing were done, quagga mussels would quickly take over waterways. They would irreparably harm water use in Idaho. These findings mark the first time a rapid response plan has been put into action for quagga mussels in Idaho.

Yellowstone National Park seeks public comment on proposed measures to help stop the spread of aquatic invasive species (AIS) into park waters. The proposals include a 30-day mandatory dry time for some types of motorized boats and sailboats before entering park waters and the prohibition of watercraft previously fouled by mussels regardless of dry time.

Quagga mussels were found in the Snake River in September 2023. Immediately afterwards, Idaho Fish and Game assisted the Department of Agriculture in their evaluation of potential treatments to eliminate the mussels, and Idaho Fish and Game quantified the fish populations found in the six-mile stretch of river where the mussels were found, and where the treatment would occur. Biologists quickly learned that the treatment caused high mortality in certain species, while others survived quite well.

The states of Oregon, Washington, and Idaho are urging people to report any feral pig sighting by calling a toll-free, public hotline, the Swine Line: 1-888-268-9219. The states use hotline information to quickly respond to a feral swine detection, helping to eradicate and curb the spread of the invasive species.
