  • Federal Legal Authorities for the Early Detection of and Rapid Response to Invasive Species

    • 2019
    • National Invasive Species Council; Biological Invasions.

    • Building on information provided by federal agencies and an inspection of the US Code and the Code of Federal Regulations, this article reviews and identifies relevant authorities to determine federal legal capacities, gaps, and inconsistencies to address (Early Detection and Rapid Response (EDRR). Although the Plant Protection Act and the Animal Health Protection Act are comprehensive authorities that address the detection of and response to organisms that threaten plant and livestock health, there is no single authority that encompasses EDRR for all invasive species. Rather, there is a patchwork of authorities that unevenly addresses various aspects of EDRR. View Early Detection and Rapid Response for more information.

  • Feral Hogs in Missouri

    • Missouri Department of Conservation.

    • Report feral hogs, don't shoot them. The take of feral hogs is prohibited on conservation areas and other lands owned, leased, or managed by the Conservation Department. Hunting hogs on other lands is strongly discouraged. Instead, report feral hog sightings to 573-522-4115, extension 3296 or use the Feral Hog Sighting and Damage Report. The Conservation Department and the U.S. Department of Agriculture Animal and Plant Health Inspection Service, along with other partners and hundreds of private landowners, are working to eradicate feral hogs in Missouri. When hunters shoot feral hogs, it complicates efforts to remove these pests. Hogs are social animals that travel in groups called sounders. Shooting one or two hogs scatters the sounder and makes trapping efforts aimed at catching the entire group at once more difficult, because hogs become trap-shy and more wary of baited sites. With their high reproductive rate, removing one or two hogs does not help to reduce populations. Anyone who observes a feral hog or damage caused by feral hogs should report it to the Conservation Department rather than shooting the animal so we can work together towards eradication.

  • Feral Swine - Managing an Invasive Species

    • USDA. Animal and Plant Health Inspection Service.

    • In response to the increasing damage and disease threats posed by expanding feral swine populations in the U.S., Congress appropriated funds to APHIS in 2014 to create a collaborative National Feral Swine Damage Management Program. The program’s overarching goal is to protect agricultural and natural resources, property, animal health, and human health and safety by managing feral swine damage. APHIS collaborates with many stakeholders—including States, Tribes, other Federal agencies, universities, and the public—to accomplish this goal.

  • Feral Swine Eradicated from Colorado Thanks to Work of State and Federal Partnership

    • Feb 12, 2020
    • Colorado Department of Agriculture

    • All known feral swine have been eliminated from Colorado thanks to a near 15-year state and federal partnership comprised of the U.S. Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS) Wildlife Services (WS), the USDA Forest Service (FS), Colorado Parks and Wildlife (CPW) and the Colorado Department of Agriculture (CDA). The partnership formed in the early 2000s as a task force to manage invasive feral swine, which root up crops and pastures causing billions in damage nationwide each year. Feral swine also spread disease to livestock, wildlife and humans. Ground-nesting birds and other wildlife are easy prey for feral swine. And the swine put native wildlife at risk by competing for resources and destroying habitats and ecosystems. 

      You can help keep Colorado free of feral swine:

      • Spread the word that in Colorado it’s illegal to possess, transport or release feral swine, wild swine species or hybrids.
      • Report sightings of feral swine or transportation activities to USDA Wildlife Services at 1-866-4-USDA-WS (1-866-487-3297) or Colorado Parks and Wildlife at 303-297-1192.

  • Field Guide To The Identification of Japanese Stiltgrass

    • Mar 2019
    • Alabama Cooperative Extension System.

    • Japanese stiltgrass (Microstegium vimineum), also called Nepalese browntop, is an aggressive invader of forest lands throughout the eastern United States. Infestations can impact the diversity of native species, reduce wildlife habitat, and disrupt important ecosystem functions. Stiltgrass is considered one of the most damaging invasive plant species in the United States. Infestations spread rapidly and the seed can remain viable in the soil for up to five years. Correct identification is necessary before beginning any management activities. Fortunately, Japanese stiltgrass has a unique combination of characteristics that make field identification possible. This publication gives simple descriptions and clear pictures of these characteristics along with details on how to distinguish several common look-a-like species. Download the full PDF version of ANR-1457, the Field Guide to The Identification of Japanese Stiltgrass with Comparisons to other Look-a-like Species  [PDF,  16.1 MB].

  • Fighting Invasive Emerald Ash Borers with Woodpeckers and Citizen Scientists

    • May 24, 2022
    • USDA. Forest Service.

    • Invasive non-native insects have been called the "wildfires of the East," given the damage they cause to trees. One pest, the emerald ash borer, has killed hundreds of millions of rural and urban ash trees. To help arborists and city planners track and treat potential outbreaks, U.S. Forest Service scientists seek efficient monitoring techniques.

  • Fire Ant Week: Stamping Out Fire Ants

    • Google. YouTube; USDA. Agricultural Research Service.

    • Fire ants cause significant harm not only to humans, but to the food we grow? Imported fire ants have invaded about 350 million acres in the U.S., and they cause approximately $8 billion in economic damages per year.

      Learn more about what’s happening with this invasive species that has spread throughout the southern U.S., and what ARS is doing about it, as the Office of Communications launches a week-long fire ant campaign (June 22-28, 2024). ARS will feature videos, articles, and interviews with our scientists who are leading the fight against these tiny invaders.

  • Fire Ants and Other Burning Problems: ARS Scientists Target Some of America's Toughest Pests

    • Jun 27, 2022
    • USDA. ARS. Tellus.

    • ARS scientists are using a unique receptor interference technology that they have developed to target fire ants. The technology is environmentally friendly and can also be directed at other existing or emerging invasive pests to provide timely, cost-efficient pest control.

  • Firefighting Cattle: Targeted Grazing Makes Firebreaks in Cheatgrass

    • Oct 1, 2020
    • United States Department of Agriculture.

    • Cattle grazing on a nearly half mile wide targeted strip of cheatgrass near Beowawe, Nevada, created a firebreak that helped limit a rangeland fire to just 54 acres this past August compared to rangeland fires that more commonly race across thousands of acres of the Great Basin. This "targeted grazing" firebreak and eight others are part of an evaluation project being managed by the Agricultural Research Service (ARS), partnering with other federal, state and local agencies and local cattle ranchers in Idaho, Nevada and Oregon. These demonstration sites are being studied so the concept's efficacy and environmental impacts can be uniformly evaluated and compared.

      Cheatgrass, also known as downy brome, is an invasive annual that dominates more than 100 million acres of the Great Basin in the western U.S. Germinating each winter, cheatgrass grows furiously in spring and dies in early summer, leaving the range carpeted in golden dry tinder. The Great Basin now has the nation's highest wildfire risk, and rangeland fires are outpacing forest fires when it comes to acreage destroyed.

  • Firewood and Invasive Pests

    • Vermont Agency of Natural Resources. Department of Forestry, Parks, and Recreation.

    • Firewood is widely recognized as a major source of non-native forest insect and disease infestations. A rule governing the importation of untreated firewood into Vermont went into effect on May 1, 2016. Visitors to Vermont State Parks, Vermont State Forests, and the Green Mountain National Forest may only bring firewood originating from Vermont or that is heat treated and in its original, labeled package. To help slow the spread of emerald ash borer within Vermont, ash firewood that has not been heat treated should not be moved outside of the Emerald Ash Borer Infested Area in Vermont.

  • Firewood Quarantine

    • New Hampshire Department of Agriculture, Markets & Food.

    • As of Jul 2011, New Hampshire has banned the importation of untreated firewood without a commercial or home heating compliance agreement. Firewood is a major source of damaging insects and diseases. This quarantine will help protect the health on New Hampshire's forests.

  • Firewood Transport as a Vector of Forest Pest Dispersal in North America: A Scoping Review

    • Feb 2021
    • Cornell University. New York Invasive Species Research Institute.

    • A cozy campfire for summer days, a warm fireplace for winter evenings– the use of firewood is an "established cultural norm". However, moving firewood from place to place can have devastating consequences, as it can spread forest pests that decimate forests to collectively cost an estimated $4.2 – $14.4 billion per year. In order to better address the problem of people moving firewood and vectoring forest pests, Solano and colleagues examined trends and gaps in the existing literature on firewood and human-mediated forest pest movement in North America. The existing literature demonstrates the risk of firewood movement, but fails to address the level of awareness the public has on such risks, or the level of effectiveness of firewood regulations to prevent forest pest spread.

  • First Genome of Spotted Lanternfly Built from a Single Insect

    • Oct 16, 2019
    • USDA. Agricultural Research Service.

    • Agricultural Research Service (ARS) scientists, in cooperation with Pacific Biosciences and Penn State University have successfully reconstructed the genome of spotted lanternfly, paving the way for understanding it's biology and behavior. Not only is it the first published genome for this pest, but no closely related species has had its genome sequenced, making the data even more important.

  • First Michigan Detection of Invasive Hydrilla Triggers Response

    • Oct 2, 2023
    • Michigan.gov. Michigan Invasive Species Program.

    • Hydrilla, considered one of the world's most invasive aquatic plants, has been detected for the first time in Michigan. The Department of Environment, Great Lakes and Energy confirmed two small populations of the plant in adjacent private ponds on residential properties in Berrien Springs in Southwest Michigan.

      The small patches of hydrilla (Hydrilla verticillata) were discovered during routine monitoring following treatment for another invasive plant, parrot feather, which was found in the pond in 2020. Both species are prohibited in Michigan, meaning it is unlawful to sell, possess or import them into the state, and both are on Michigan’s invasive species watch list due to their potential environmental threat. Any suspicious aquatic plants should be reported as soon as possible to EGLE-WRD-AIP@Michigan.gov. Include close-up photos and provide the location of the detection in your report. More information on identifying and reporting invasive aquatic plants can be found at Michigan.gov/Invasives.

  • First Successful Rat Removal Project in the Marquesas Protects Seabird Populations

    • Feb 8, 2019
    • Island Conservation.

    • The future is looking a little brighter for seabirds in French Polynesia following the first successful removal of invasive rats in the Marquesas Archipelago. The project, implemented by the Societe d’Ornithologie de Polynesie (Manu), Island Conservation, BirdLife International and Association Vaiku’a i te manu o Ua, will protect a nationally significant population of 90,000 Sooty Terns. Invasive rats present on the island devoured seabird eggs and chicks and native plants. Free from invasive rats, seabirds can once again safely nest and native plants can grow tall and thrive.
