USDA Forest Service researchers are monitoring the effects of white-nose syndrome, a fungal disease from Eurasia that has decimated cave-hibernating bats across the U.S. since its arrival in 2006. "The fungus that causes white-nose syndrome grows on bats in the wintertime. It causes them to wake up during their hibernation and burn their fat reserves," says Phillip Jordan, wildlife biologist. Jordan is among the experts featured in a new video, Bats on the Brink. Forestry technician Virginia McDaniel created and produced the video.

Invasive species pose a threat across the United States and its territories, but they can be especially challenging for the U.S. South Pacific territory of American Samoa. Among the invasive pests menacing the territory are several non-native fire ant species. 

Giant reed, Arundo donax, is a large, fast-growing invasive grass that has invaded at least 100,000 acres of "riparian" habitat in the southwestern and southeastern U.S. and is present as far north as Ohio and Washington State. Watch this video to learn how ARS researchers are using biocontrol (insects) to reduce the presence of this invasive plant.

ARS entomologist is developing microbial pesticides for the effective control of mosquitoes and the pathogens they transmit.

Signed into law in November 2021, the Bipartisan Infrastructure Law (BIL), also known as Public Law 117-58 Infrastructure Investment and Jobs Act (IIJA), provides ~$1.2 trillion in funding to federal agencies for work related to transportation, energy, water, internet, and natural-resources related infrastructure. This includes resources for the Departments of Agriculture (USDA), the Interior (DOI), and Commerce (DOC) that are directly or indirectly tied to invasive species management.

Aquatic invasive species cause tremendous harm to our environment, our economy, and our health. They can drive out and eat native plants and wildlife, spread diseases, and damage infrastructure. The U.S. spends billions of dollars every year to manage and control these aquatic invaders and protect the nation's waters. Although prevention is the most effective approach to eliminate or reduce the threat of aquatic invasive species,  Early Detection and Rapid Response (EDRR)  serves as a failsafe when prevention measures are ineffective or unavailable.

Recognizing the need for action, the U.S. Department of the Interior identified advancing a National EDRR Framework for invasive species as a priority for Bipartisan Infrastructure Law funding and took steps to invest in supporting components of such a framework. One such critical component was the establishment of a pilot Rapid Response Fund for Aquatic Invasive Species that can be used to assess and support response actions for quick containment or eradication of newly detected species.

The Bureau of Land Management is approving seven herbicide active ingredients to control noxious weeds and invasive species on public lands. BLM field and district offices can now begin considering the use of these tools in efforts to control and eradicate noxious weeds and invasive plant species on the public lands they manage. 

The Bureau of Land Management has released the final programmatic environmental impact statement for fuels reduction and rangeland restoration in the Great Basin. This programmatic environmental impact statement (PEIS) is intended to further efforts to conserve and restore sagebrush communities within a 223 million-acre area that includes portions of Idaho, Oregon, Washington, California, Nevada and Utah.

Sagebrush communities in the Great Basin are a vital part of Western working landscapes and are home to over 350 species of plants and wildlife. Intact sagebrush communities are disappearing within the Great Basin due to increased large and severe wildfires, the spread of invasive annual grasses, and the encroachment of pinyon-juniper. The Great Basin region is losing sagebrush communities faster than they can reestablish naturally. Fuels reduction and rangeland restoration treatments can reduce fire severity, increase sagebrush communities' resistance to invasive annual grasses and improve their ability to recover after wildfires.

ARS researchers are working to understand the impact of a changing climate on bee health. In observance of National Pollinator Week, Tellus presents a special article authored by two of ARS’s leading bee researchers.

The Bureau of Reclamation has launched a new prize competition seeking innovative solutions for the 100-percent eradication of invasive quagga and zebra mussels from large reservoirs, lakes and rivers in a cost-effective and environmentally sound manner. Invasive mussel infestations pose significant logistical and economic challenges for local communities, recreationists, and water managers by potentially disrupting water deliveries, increasing facility maintenance cost, and impacting the local ecology.

A new workshop unites practice with research on the beneficial effects of fire. As wildfires and toxic smoke pour across North America, millions of people are experiencing the harm that fire can cause. But fire can also be an ally in protecting natural landscapes when it is deployed in the right ways. That’s why ARS researchers recently led a workshop designed to meld the insights of science with the day-to-day operations of fire management, for professionals who use the practice known as prescribed burning (cultural control).

Currently, most cogongrass is controlled with herbicides, which only serve as a temporary solution. The herbicides must be reapplied every 6-12 months. ARS scientists in the U.S. and overseas are investigating biological control of cogongrass by collecting and studying insects that feed on the grass where the weed originated. These insects will be screened over many years to determine if they will be safe, and only those that cause no harm to valued plants will be released.

Urban legends about the origins of canal grass in Panama abound, but the Smithsonian has new evidence that puts the question to rest. Canal grass is an invasive weed, native to Asia. Because its tiny seeds blow in the wind, it readily invades clearings and spreads to form impenetrable stands by budding from tillers and rhizomes. Once established, canal grass is challenging to eliminate.

USGS published a dataset called "Catalog of U.S. Federal Early Detection/Rapid Response Invasive Species Databases and Tools." The catalog, developed in collaboration with the National Invasive Species Council Secretariat, is a multi-sheet spreadsheet that contains openly available, online, federally supported databases and tools dealing with various aspects of a potential national early detection and rapid response invasive species framework.

U.S. Customs and Border Protection (CBP) agriculture specialists have already intercepted a dozen significant and potentially destructive pests this year at various ports of entry in Florida as part of the agency's all-encompassing efforts to safeguard American agriculture.

Unknown pests pose a significant risk in agriculture due to a lack of knowledge in controlling the pests and the extent of damage they can cause to crops. U.S. Department of Agriculture (USDA) entomologists recently classified eight pests discovered by CBP agriculture specialists in Florida as first-in-the-nation interceptions and another pest as a new species.

U.S. Customs and Border Protection (CBP) agriculture specialists throughout the United States are busy inspecting cut flower shipments ahead of Valentine’s Day in order to protect the nation from agricultural and floral pest risks.

The U.S. Customs and Border Protection’s (CBP) Office of Field Operations discovered 90 giant African land snails in a traveler’s luggage at Detroit Metropolitan Airport on June 30, 2024. The passenger had arrived from Ghana. The snails were seized and were “humanely euthanized,” the CBP says. The release says euthanizing the snails was necessary “to ensure they did not enter the ecosystem and cause havoc to U.S. agriculture.” 

A recent moth interception by U.S. Customs and Border Protection (CBP) agriculture specialists at Detroit Metropolitan Airport (DTW) is now considered to be the first encounter of the species since 1912.

Agriculture specialists play a vital role at our nation’s ports of entry by preventing the introduction of harmful exotic plant pests and foreign animal diseases into the United States. Learn more about how CBP agriculture specialists work in Protecting Agriculture.
