FISC compiles invasive species lists that are revised every two years. Professional botanists and others perform exhaustive studies to determine invasive plants that should be placed on the lists.

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 U.S. Fish and Wildlife Service Aquatic Invasive Species Program supports a dedicated group of people who work closely with state invasive species coordinators, non-governmental groups, private landowners and many others in their day-to-day activities.

Research and commerce use a two-pronged ‘fork’ approach to deal with invasive fish. As many anglers know, carp are not welcome when found dangling from the hook. Classified by U.S. government as an invasive species and known colloquially as a “trash fish,” carp can take over and devastate every watery environment they enter. They’re not particularly well known in this country as good eating fish, either. To help curb the numbers of invasive fish, researchers and commerce are using a two-pronged ‘fork’ approach to deal with the invasive fish.

The spread of plant diseases and pests is on the rise due to a changing climate. Plants are humans’ best friends and main allies in life on earth. Plants are responsible for 98 percent of the oxygen we breathe and make up 80 percent of our daily calorie intake. However, we often take them for granted, not realizing the importance of keeping them healthy. Every year up to 40 percent of food crops is lost to plant pests and diseases. These losses in both yields and income have a devastating effect on the poorest communities who base their livelihoods on agriculture.

Giant threats to Arkansas's fish and water are lurking under the surface somewhere right now. The Arkansas Game and Fish Commission needs boaters' help in stopping these terrors before they spread any further. Matt Horton, the AGFC's Aquatic Nuisance Species program coordinator, says 36 aquatic nuisance species have been documented in Arkansas, including plants, fish, mussels and other types of organisms. Some of the more well known species include giant salvinia, silver carp, northern snakeheads and zebra mussels, but these are just a few of the species that can pose significant ecological and economic harm, as well as a risk to human health.

Just like when fighting a virus, Horton says the best plan of attack is to prevent it from spreading to new areas. Here are some ways everyone can fight aquatic nuisance species in Arkansas to keep our waters healthy and accessible for angling and boating enjoyment.

The Flood and Storm Tracker (FaST) maps were created to help assess impacts on nonindigenous aquatic species distributions due to flooding associated with storms. Storm surge and flood events can assist expansion and distribution of nonindigenous aquatic species through connection of adjacent watersheds, backflow of water upstream of impoundments, increased downstream flow, and/or creation of freshwater bridges along coastal regions. These maps will help natural resource managers determine potential new locations for individual species, or to develop a watchlist of potential new species within a watershed.
