Thousand cankers disease is a fungal disease of walnuts (Juglans spp.) that is carried from tree to tree by a small bark beetle called the walnut twig beetle (Pityophthorus juglandis). It has killed countless ornamental black walnut trees in the western U.S. and was found for the first time in the eastern U.S. in 2010. The first recorded incident of thousand cankers disease in North Carolina (Haywood County) was confirmed in late fall, 2012. Please report the location and descriptions of potentially positive trees to 1-800-206-9333 or newpest@ncagr.gov.

Thousands of invasive fish have been removed from the Chesapeake Bay watershed at the Conowingo Dam earlier this year and donated to local food banks through a continuing partnership between Maryland Department of Natural Resources and others. During the 2024 season, which ran from March to June, more than 18,000 pounds of invasive fish (blue catfish, flathead catfish, and northern snakehead) were removed from Maryland waters.
