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.

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.

Colorado Parks and Wildlife.
The Colorado Division of Wildlife is monitoring the state's waters for the introduction of an aggressive invasive species, the rusty crayfish. Rusty crayfish were found for the first time in Colorado during routine sampling operations in 2009 in the Yampa River drainage between Steamboat Springs and the town of Yampa. Because of their larger size and more aggressive nature, rusty crayfish can impact fish populations by consuming small fish and fish eggs, and negatively impact fish and spread unwanted aquatic plants by aggressively harvesting underwater plant beds. Learn more how to identify the rusty crayfish, how to stop the spread and how to report sightings.

Tribal, state and local governments will join forces at Lake Roosevelt this week to combat the spread of northern pike, recently recorded just two dams away from critical Columbia River salmon habitat. “We are at a critical moment in time where northern pike have not spread into salmon habitat,” said Kelly Susewind, director of the Washington Department of Fish and Wildlife. “If northern pike move downstream, the State of Washington will consider this an environmental emergency. We need to work together to stop northern pike.”
