As part of the ongoing response to the recent discovery of the Emerald Ash Borer (EAB) within the state, Vermont has joined the United States Department of Agriculture (USDA)'s 31-state quarantine boundary. The quarantine will help reduce the movement of infested ash wood to un-infested regions outside of Vermont's borders. Ash wood may not be moved from Vermont to Maine, Rhode Island, or 7 counties in New Hampshire because the pest has not been identified in these states and counties. Vermont is also developing a series of slow-the-spread recommendations, initially including recommendations for handling logs, firewood, and other ash materials. To learn more about these recommendations, to see a map indicating where EAB is known to occur in Vermont, and to report suspected invasive species like EAB, visit vtinvasives.org

In some parts of the state, Vermonters are noticing the return of a disturbing sight in our forests and backyards: masses of spongy moth caterpillars. The Vermont Agency of Agriculture, Food and Markets (VAAFM) and Department of Forests, Parks, and Recreation (FPR) have received numerous inquiries from concerned citizens regarding large numbers of spongy moth caterpillars, Lymantria dispar dispar, (also known as LDD, formerly gypsy moth). While the spongy moth can emerge anywhere in the state, unusually high populations observed last year and again this spring are localized in western areas of Vermont. More information regarding the impacts of spongy moths on trees and forests can be found at https://fpr.vermont.gov/spongy-moth.

Thousand cankers disease (TCD) is a disease complex native to the western United States and primarily affects black walnut, Juglans nigra. This disease is the result of the combined activity of a fungus, Geosmithia morbida, and the walnut twig beetle WTB), Pityophthorus juglandis. On January 12, 2015, the the Maryland Secretary of Agriculture issued a quarantine order to minimize the risk of moving infested material out of the limited action area in Cecil County, and to provide confidence in Maryland walnut products moving into neighboring states from non quarantined areas. The 2015 quarantine order has been updated to include all of Baltimore City and part of Baltimore County [PDF, 1.2 MB]. The new quarantine [PDF, 1.0 MB] was signed on May 1, 2019 by the Maryland Secretary of Agriculture.

The Washington Invasive Species Council approved an updated statewide strategy to prevent invading plants and animals from taking hold in the state’s forests, waters and farms.

The strategy calls for a broad range of actions focusing on preventing new species from establishing here, educating the public and rapidly deploying when species are found to prevent their spread. The 5-year strategy (2020-2025) is available at Washington Invasive Species Council - Reports.

After three years without confirmed detections, the Washington State Department of Agriculture (WSDA) and the United States Department of Agriculture (USDA) have declared the northern giant hornet (Vespa mandarinia) eradicated from Washington and the United States.
