Spotlights

  • eDNA from Invasive Silver Carp Identified in Lake Erie’s Presque Isle Bay

    • Jul 21, 2022
    • Pennsylvania Fish and Boat Commission.

    • The Pennsylvania Fish and Boat Commission (PFBC) announced that it has conducted targeted invasive carp sampling in Presque Isle Bay, Erie County, after the U.S. Fish and Wildlife Service (USFWS) detected the presence of Silver Carp environmental DNA (eDNA). While no physical invasive carp specimens have been detected, the PFBC has requested that the USFWS collect additional water samples from Presque Isle Bay in the fall when more favorable environmental conditions are present for eDNA sampling. Members of the public can report sightings of aquatic invasive species to the PFBC using its online form.

  • Pennsylvania Bans Sale of Three Invasive Plants: Ravenna Grass, Glossy Buckthorn, Common Buckthorn

    • Feb 4, 2022
    • Pennsylvania Department of Agriculture.

    • The Pennsylvania Department of Agriculture has added ravenna grass, glossy buckthorn and common buckthorn to a list of noxious weeds — plants that cannot be legally sold or cultivated in the state. The non-native plants spread aggressively into wooded areas and fields, crowding out beneficial plants and disrupting native ecosystems. The ban on sale and cultivation will take effect April 5, 2022 with enforcement phased in over the next year.

  • Pennsylvania Fish and Boat Commission Urges Anglers And Boaters To Help Prevent Spread Of Invasive New Zealand Mudsnails

    • Apr 20, 2022
    • Pennsylvania Fish and Boat Commission.

    • Recent surveys by the PFBC and partner organizations have detected New Zealand mudsnails, roughly the size of a match head, in several popular cold-water trout fisheries in central and eastern Pennsylvania. In some infested waters, New Zealand Mudsnails have the potential to reach densities of hundreds or even thousands of snails per square foot. These snails are not harmful to humans but can compete with and negatively impact native freshwater invertebrate species, such as other snails and aquatic insects.

      Until recently, New Zealand Mudsnails were known to occur only in Lake Erie, Erie County; Spring Creek and Bald Eagle Creek, Centre County; and the Little Lehigh Creek in Lehigh and Berks counties. Surveys during 2020 revealed populations of snails in Trindle Spring Run, Cumberland County; Codorus Creek, York County; and Valley Creek, Chester County; prompting expanded surveys. Members of the public who observe suspected New Zealand Mudsnails or other aquatic invasive species may report their sightings to the Commission.

  • Pennsylvania Phasing in Ban of Invasive Japanese Barberry

    • Nov 12, 2021
    • Pennsylvania Department of Agriculture.

    • The PA Department of Agriculture added Japanese Barberry, or Berberis thunbergii, to a list of noxious weeds — plants that cannot be legally sold or cultivated in the state. The popular, non-native, ornamental shrub forms dense, prickly thickets that crowd out plants and disrupt native ecosystems. It is also thought to harbor black-legged ticks that spread lyme disease. The ban on sale and cultivation took effect October 8, 2021. Enforcement of the ban will be phased in over two years to allow time for nurseries to eliminate it from their stock, find non-harmful alternatives, and develop seedless, sterile varieties that pose less threat to the environment and agriculture. Landscape and nursery businesses will receive notices of the timeline, procedures and exemption process for sterile varieties. Property owners should consider eliminating the shrubs on their land.

      Effective October 8, 2021, the department added two other plants to the noxious weed list: garlic mustard, Alliaria petiolata, and Japanese stiltgrass, Microstegium vimineum. These plants are generally not sold in nurseries but are invasive and common in Pennsylvania. Landowners with these plants on their property are encouraged to remove them.

  • Spotted Lanternfly Alert

    • 2021
    • Pennsylvania Department of Agriculture.

    • The Spotted Lanternfly is an invasive species native to Asia. In 2014 it was found in Pennsylvania, and has since spread to multiple counties which are now quarantined. If you see a spotted lanternfly, it's imperative to immediately report it online or via phone by calling 1-888-4BADFLY. Especially if you are not inside the quarantine zone.

      What else? Kill it! Squash it, smash it...just get rid of it. In the fall, these bugs will lay egg masses with 30-50 eggs each. These are called bad bugs for a reason, don't let them take over your county next. In March 2021, the Pennsylvania Department of Agriculture (PDA) added 8 additional counties to the Spotted Lanternfly Quarantine, for a total of 34 Pennsylvania counties now in quarantine.

  • Thousand Cankers Disease

    • Pennsylvania Department of Agriculture.

    • On Aug. 9, 2011, the department in cooperation with the U.S. Department of Agriculture and Penn State Cooperative Extension confirmed the presence of Thousand Cankers Disease in black walnut trees in Bucks County. Since this pest complex cannot be eradicated in Pennsylvania, and since black walnut is of high value to the forest products industry and to forest and urban ecologies, the Pennsylvania Department of Agriculture is joining with state and federal agencies and Penn State Cooperative Extension to slow the spread of TCD in the state through monitoring and quarantine. For more information or to report a possible case of Thousand Cankers Disease on walnut please contact your Pennsylvania local county cooperative extension office or contact the Invasive Species Hotline at 1-866-253-7189 or Badbug@pa.gov.

    • The Woody Invasives of the Great Lakes Collaborative provides information related to woody invasive species identification, distribution, impacts, regulatory status, and control and management. The collaborative has also developed recommendations on trees, shrubs and vines that gardeners and landowners can plant as alternatives to known woody invasives. The WIGL Collaborative was founded in early 2018 and is coordinated by the staff of the Midwest Invasive Plant Network (MIPN).
