A USDA NIFA Coordinated Agriculture Project.

This short course is an asynchronous, professional, online short course that was created to provide you with knowledge about the science, application, and regulation of classical weed biological control. This class was developed by professionals with real world experience managing invasive plants.
Note: Course is free thanks to funding from the USDA, Forest Service.

Clean Boats, Clean Waters reminds boaters to clean, drain and dry their equipment to prevent the spread of aquatic invasive species.

The Clean Boats, Clean Waters watercraft inspection program is an opportunity to take a front line defense against the spread of aquatic invasive species. Program inspectors are trained to organize and conduct a boater education program in their community. Adults and youth teams educate boaters on how and where invasive species are most likely to hitch a ride into waterbodies. Inspectors perform boat and trailer checks for invasive specie​s, distribute informational brochures, and collect and report any new AIS presence in waterbodies. 

The Clemson University Department of Plant Industry destroyed the first secondary nests of the yellow-legged hornet this month in South Carolina near Hilton Head Island. Yellow-legged hornets were also detected in November 2023 in a trap in South Carolina. 

The brown marmorated stink bug (BMSB), Halyomorpha halys, originally from East Asia, is an invasive pest that is present throughout much of the United States. It is attracted to the outside of houses on warm fall days in search of overwintering sites and can enter houses in large numbers. The brown marmorated stink bug is also a serious economic threat to fruit crops, garden vegetables, and many ornamentals. In a changing climate, agricultural losses from insect pests like BMSB are expected to increase.

USDA ARS scientists are fighting back by developing traps, sequencing the bug’s genome, and testing parasitic wasps as biocontrols. Midwest Climate Hub research fellow, Dr. Erica Kistner-Thomas is contributing to that fight through modeling the potential distribution and abundance of BMSB under future climate scenarios using a bioclimatic niche model. For more on Erica’s work, see: Climate Change Impacts on the Potential Distribution and Abundance of the Brown Marmorated Stink Bug (Hemiptera: Pentatomidae) With Special Reference to North America and Europe.

The Japanese beetle (Popillia japonica Newman) is a highly destructive plant pest of foreign origin. It was first found in the United States in 1916 and has since spread to most states east of, and immediately to the west of, the Mississippi River. It has also spread to some western States, but tough regulations and careful monitoring have prevented its establishment elsewhere. The Japanese beetle has become a serious plant pest and a threat to American agriculture.

Scientists with USDA’s ARS and APHIS have developed an integrated pest management (IPM) program that combines biological, cultural, and chemical strategies. In support of this plan, the Midwest Climate Hub Fellow, Dr. Erica Kistner-Thomas modeled how climate change may impact the distribution and voltinism (generations produced per year) of the Japanese beetle. Model projections indicate increases in temperature would enable northward range expansion across Canada while simultaneously shifting southern range limits in the United States northward. For more on Erica’s work, see: The Potential Global Distribution and Voltinism of the Japanese Beetle (Coleoptera: Scarabaeidae) Under Current and Future Climates.

Palmer amaranth (Amaranthus palmeri S. Watson) is an annual plant in the pigweed family (Amaranthaceae). It is native to the southwest United States/northern Mexico deserts and is currently increasing its range across the country. USDA NRCS, their partners, as well as farmers and landowners are working to eradicate these infestations before they spread to new areas. Midwest Climate Hub fellow, Dr. Erica Kistner-Thomas is getting a jump on how the distribution of Palmer amaranth will change from current to future climate conditions. Climate change is going to benefit this heat-tolerant weed by lengthening its growing season, boosting seed production and expanding its potential U.S. geographic range.

Climate change in the Midwest is causing winters to be milder, on average, and is increasing the frequency and severity of heavy precipitation events. These changes are increasing the prevalence and range of pests and invasive species, which has wide-ranging impacts on human health, food security, and the management of important ecosystems.

A new invasive species coalition is celebrating significant milestones in preventing expansion of invasive species after the first anniversary of an important agreement. The North American Invasive Species Management Association, Wildlife Forever, the National Park Service, and the U.S. Fish and Wildlife Service are working to implement on-the-ground strategies to engage the American public and help prevent the spread of invasive species under the new agreement.

Provides comprehensive information on cogongrass in Georgia along with links to other southeastern state efforts on cogongrass. To date, Alabama, Florida, Georgia, Louisiana, Mississippi, South Carolina and Texas have on-going research, education and/or control programs that are supported by university, state and federal agency cooperators.

To prevent the spread of aquatic invasive species, the Pacific States Marine Fisheries Commission, U.S. Fish and Wildlife Service, Western Regional Panel on Aquatic Nuisance Species, and others are making information available to boat haulers, auctioneers, marinas, manufacturers, and brokers to make it easy to comply with state, provincial and federal laws, prevent costly delays in transporting or selling boats, and help reduce the spread of aquatic invasive species.

In December 2021, the Pacific States Marine Fisheries Commission (PSMFC) initiated a program to prevent delays during the transport of watercraft destined for the states of Washington, Oregon, Idaho, and Montana. The program, Call Before You Haul, provides a toll-free number (1-844-311-4873) boat transporters can call prior to transporting watercraft from outside the Pacific Northwest to one of the aforementioned states. The program was piloted in 10 states.

The Call Before You Haul 1.0 program was initiated in late 2022 prevent the introduction and establishment of quagga and zebra mussels in the Columbia River Basin states and prevent the movement of aquatic invasive species via trailered watercraft. Call Before You Haul 1.0 consisted of creating a 24-7 toll-free number for boat transporters and working directly with state agencies that permit interstate oversize/overweight loads, including watercraft, to raise boat transporter awareness about trailered watercraft as a vector for aquatic invasive species. There remains a significant number of infested watercraft coming from the Great Lakes regions of the United States and Canada to western states.

Call Before You Haul 2.0 expanding in February 2024, is an effort to work collaboratively with Great Lakes region entities to reduce interstate transport of aquatic invasive species — for the benefit of all states and provinces.

The annual Lionfish Challenge is an incentive program that rewards harvesters for their lionfish removals. With a tiered system, everybody can be a winner. The participant who harvests the most lionfish will be crowned the Lionfish King/Queen. The Challenge is open now and will run through November 1. You can register for the 2020 Lionfish Challenge and find more information at FWCReefRangers.com/Lionfish-Challenge. Questions regarding the challenge can be sent to Lionfish@MyFWC.com.
