In September 2016, Palmer amaranth, Amaranthus palmeri, was found in Minnesota. To date, it has been documented in Douglas, Jackson, Lyon, Redwood, Todd, and Yellow Medicine counties. The Minnesota Department of Agriculture (MDA), University of Minnesota Extension, USDA, landowners and other partners are working to eradicate these infestations before they can spread to new areas. Be proactive and prevent Palmer amaranth establishment. Familiarize yourself with Palmer amaranth identification and actively look for it in crop fields, borders, ditches, conservation lands and around dairies. If you suspect Palmer amaranth on your property, immediately call your local U of M Extension Educator or IPM Specialist, crop consultant and/or the MDA’s Arrest the Pest (888-545-6684) to report locations.

Several local and federal agencies today took another step in protecting America's Everglades by releasing an insect reared to combat the invasive Brazilian peppertree. The insects, known as thrips, were reared as part of a joint partnership between the South Florida Water Management District (SFWMD), the U.S. Department of Agriculture (USDA), U.S. Army Corps of Engineers (USACE), Florida Department of Environmental Protection, the National Park Service, the Florida Fish and Wildlife Conservation Commission (FWC), the Florida Department of Agriculture and Consumer Services (FDACS) and the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) to combat invasive plants in South Florida's ecosystem.

The Partners Program provides technical and financial assistance to private landowners and Tribes who are willing to work with us and other partners on a voluntary basis to help meet the habitat needs of our Federal Trust Species.

As climate change reduces the frequency and intensity of killing freezes, tropical plants and animals that once could survive in only a few parts of the U.S. mainland are expanding their ranges northward, a new U.S. Geological Survey-led study has found. The change is likely to result in some temperate zone plant and animal communities found today across the southern U.S. being replaced by tropical communities. These changes will have complex economic, ecological and human health consequences, the study predicts. Some effects are potentially beneficial, such as expanding winter habitat for cold-sensitive manatees and sea turtles; others pose problems, such as the spread of insect-borne human diseases and destructive invasive species.

ARS researchers created a new tool, called Pathogen and Tree Fruit Health Map (PATHMAP), which will connect growers in different states and allow them to share important data regarding tree fruit diseases, disorders, and insect pests. This online interactive tool will enable growers to modify and adjust their pathogen and pest control programs based on real-time data, provide quick access to time-sensitive data, give them access to experts in the field, and provide access to previous years observations and track current diseases, disorders and pests.

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.

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 can report sightings of aquatic invasive species to the PFBC using its online form.

Northern snakeheads can be confused with native Pennsylvania species like the Bowfin and Burbot. For help telling them apart, refer to various identification guides.

The Pennsylvania Governor’s Invasive Species Council shared findings from the first statewide survey of impacts from invasive plants, insects, pathogens and animals, and announced that a pilot test of a regional invasive species management program will launch this summer. The Governor’s Invasive Species Council conducted the Pennsylvania Invasive Species Impacts Survey last fall to hear directly from Pennsylvanians about impacts they’re experiencing from invasives.
