Spotlights

  • Delaware Invasive Species Council.
    Be on the lookout for these up-and-coming invaders! They might not be in Delaware yet, but our best defense is early detection and rapid response!
  • Delaware Department of Agriculture.
    Emerald ash borer (EAB), a destructive insect from Asia that attacks and kills ash trees, has been confirmed at two new sites in Delaware: one near Middletown, New Castle County, and another near Seaford, Sussex County. Originally found in northern Delaware in 2016, the new detections create added urgency for homeowners and municipalities to determine if they have ash trees on their property and decide on possible management options. Current guidelines recommend the removal or treatment of ash trees if located within 15 miles of a known infestation. Because Delaware is geographically small and EAB can go undetected for years, residents are urged to educate themselves now and take action.
  • University of Delaware Cooperative Extension.
    Plants for a Livable Delaware is a campaign to identify and promote superior plants that thrive without becoming invasive. Visit the University of Delaware's Extension Program for more information on sustainable landscaping.
  • Delaware Department of Agriculture.
    The spotted lanternfly – a destructive, invasive plant hopper – has been confirmed in New Castle County. Delaware is the second state to have found the insect which was first detected in the United States in 2014, in Berks County, PA. The spotted lanternfly has now spread to 13 Pennsylvania counties.This insect is a potential threat to several important agricultural crops including grapes, apples, peaches, and lumber. State plant health and forestry officials are providing information, fact sheets, photographs, and links to other resources at de.gov/hitchhikerbug. Early detection is vital for the protection of Delaware businesses and agriculture.
  • Delaware Department of Natural Resources and Environmental Control. Division of Fish and Wildlife.
    Northern snakeheads (Channa argus), an invasive fish, have recently been confirmed in Delaware waters. Three adult snakeheads were collected from the Delaware portion of the Nanticoke watershed: Broad Creek in Laurel, Nanticoke Branch upstream of Seaford, and the Marshyhope at Woodenhawk. The Fisheries Section asks that any possible snakehead catches in any Delaware waters be reported by emailing a photograph and details to edna.stetzar@state.de.us
