  • Invasive Species Are Taking Over Ohio Forests

    • Jun 15, 2022
    • University of Cincinnati.

    • A new botanical survey of southwest Ohio found that invasive species introduced to the United States over the past century are crowding out many native plants. Biologists from the University of Cincinnati are retracing two exhaustive surveys conducted 100 years apart to see how the Queen City's plant diversity has changed over the past two centuries. They focused their attention on undeveloped parts of cemeteries, banks of the Mill Creek and public parks that have remained protected from development during the last 200 years. The study, titled "The rise of nonnative plants in wooded natural areas in southwestern Ohio," was published in June in the journal Ecological Restoration.

  • Gone Fishing? Biologists Share How Anglers Can Support Healthy Native Fish Populations

    • Jun 15, 2022
    • USDA. Forest Service.

    • Late spring heralds the start of open water fishing season. For the casual angler, it's easy to take for granted the abundance of fish this time of year. However, many species, especially native fish, can use their help. "There are so many issues affecting the health of fish populations – barriers caused by dams and roads that cross streams fragment fish habitat. Water is diverted out of streams for other uses," said Tina Hopkins, the regional fisheries program manager for the Forest Service’s Intermountain Region. "But perhaps the biggest threat across the country is aquatic invasive species."

      Fisheries biologists from around the country have recommended a few ways that anglers, boaters and recreators can do their part to ensure healthy fish stocks for seasons to come. Here is their advice to recreators, in their words:

      • "Consult your lawbook, know the rules, and please don’t move fish around."
      • "It is extremely important that anglers clean their boats, trailers, waters, and gear when they are done fishing for the day."
      • "Every drainage is going to be different, so anglers should be informed about where they are fishing."

  • USDA Asks for Help Protecting Citrus in the Lower Rio Grande Valley

    • Jun 10, 2022
    • USDA. Animal and Plant Health Inspection Service.

    • The U.S. Department of Agriculture’s Animal and Plant Health Inspection Service (APHIS) needs your help safeguarding Texas citrus from invasive citrus pests and diseases currently threatening livelihoods and agricultural production in the Lower Rio Grande Valley. APHIS employees in Cameron, Hidalgo, Willacy and Zapata counties are working with the Texas Department of Agriculture (TDA) to inspect and survey fruit trees in residential yards and commercial properties for signs of invasive fruit flies and citrus diseases, such as citrus canker and citrus greening. These pests and diseases, if allowed to become established or spread, could devastate grapefruit, sweet and sour orange, key lime, sweet lemon, and other types of fruit production in that area.

  • State Agricultural Officials Ask Public to be on Alert for Hatching of Invasive Spotted Lanternfly Eggs

    • May 23, 2022
    • Massachusetts Department of Agricultural Resources.

    • Have you recently planted maple, crabapple, or other trees? MDAR is asking everyone to check them for spotted lanternfly egg masses or recently hatched nymphs after we were alerted that trees or shrubs with SLF egg masses may have been recently shipped to Massachusetts. Please give all nursery stock a thorough check (including pots or other containers), especially if the plants have tags that indicate they are from Pennsylvania, New Jersey, or other SLF-infested states, and report any finds.

  • Proposed Common Name Change for Asian Giant Hornet and Other Hornets

    • Entomological Society of America.

    • The Entomological Society of America (ESA) is accepting comments until June 10, 2022 on a proposed common name for Vespa mandarinia and two related species of Vespa hornets.  Although Vespa mandarinia has been detected in the Pacific Northwest, the other two hornets are not known to occur in the United States.  Currently, Vespa mandarinia is being called many different names in the popular press, but no ESA authorized common name has been established. See Common Names section for more information as it becomes available.

  • Plant Protection Today - PPQ's Ohio ALB Eradication Staff Continue to Win the Beetle Battle

    • May 31, 2022
    • USDA. APHIS. Plant Protection Today.

    • Last month PPQ's Asian Longhorned Beetle (ALB) Eradication Program in Ohio celebrated another victory—the ALB quarantine is officially 7.5 square miles smaller! This invasive beetle from Asia is a destructive wood-boring pest that feeds on maple and other hardwoods, eventually killing them. After completing their final round of tree inspection surveys, the ALB staff reported no sign of the beetle in a portion of East Fork State Park in Clermont County, Ohio.

      "Inspecting ALB host trees is painstaking work, and the staff meticulously survey for the pest," said ALB National Policy Manager Kathryn Bronsky. "It’s been three years since the last time we've lifted ALB quarantine restrictions in Ohio, and this is the first removal of the initial area placed under quarantine. That makes this success especially gratifying."

  • NYDEC Launches New Aquatic Invasive Species Requirements for Motorized Boats in Adirondack Waters

    • Jun 6, 2022
    • New York State Department of Environmental Conservation.

    • The New York State Department of Environmental Conservation (DEC) has announced measures to prevent the further spread of aquatic invasive species in the Adirondacks. Recent changes to state Environmental Conservation Law become effective on Wednesday, June 8, 2022, and require motorized boat users to obtain certification that they have inspected and removed potentially harmful aquatic invasive species before launching in waters in, and immediately adjacent to, the Adirondack Forest Preserve. To learn more about the New York State Watercraft Inspection Steward Program, the new certification requirements, and where to find a boat steward, please visit DEC's website.

  • Assessing Pollinator Friendliness of Plants and Designing Mixes to Restore Habitat for Bees

    • Jan 2022
    • USDA. FS. Rocky Mountain Research Station.
      General Technical Report; RMRS-GTR-429.

    • The worldwide decline in bee populations is threatening the delivery of pollination services, thus leading to the development of pollinator restoration strategies. In the United States, one way to protect and restore bee populations is to use seed mixes composed of pollinator-friendly native plants to revegetate federal lands following disturbance.

      Scientists assessed the attractiveness and use by bees of 24 native plant species that are standard for revegetation projects (focal plants) on national forest lands in western Montana.

  • Department Expands Spotted Lanterfly Quarantine Zone

    • Jan 20, 2022
    • Maryland Department of Natural Resources.

    • The Maryland Department of Agriculture (MDA) expanded its spotted lanternfly quarantine.  A quarantine order first issued by the state secretary of agriculture in October 2019 for Harford and Cecil counties is still in effect, but has been expanded this year to also include: Anne Arundel, Baltimore, Carroll, Frederick, Howard, Kent, Montgomery and Washington counties, as well as Baltimore City. This quarantine is effective immediately, and restricts the movement of regulated articles that might contain the spotted lanternfly in any of its life stages, including egg masses, nymphs, and adults.

      See additional resources on the Maryland Department of Agriculture's site for Spotted Lanternfly for up-to-date information. For questions related to the quarantine, permitting, treatment, or to report a sighting of the spotted lanternfly, especially outside of the quarantine zone, call 410-841-5920 or email DontBug.MD@maryland.gov. If you report a spotted lanternfly via email, please provide the location of the sighting and your contact information.
