Office of the Governor (Washington).
Washington Governor Jay Inslee has issued an emergency order (PDF| 174 KB) to address the exponential increase in the European green crab population within the Lummi Nation’s Sea Pond and outer coast areas. The European green crab is a globally-damaging invasive species that, if they become permanently established, will particularly harm endangered species, impact resources that are part of the cultural identity of the tribes and native peoples, and affect small businesses.

Pennsylvania Agriculture Secretary Russell Redding today announced that twelve counties have been added to Pennsylvania's Spotted Lanternfly quarantine zone ahead of the 2020 spring hatch. With this addition, the quarantine (PDF | 506 KB) for this invasive pest is now at 26 counties. The new dozen counties are not completely infested, but rather have a few municipalities with a known infestation (PDF | 803 KB) which led to a quarantine being placed on the entire county out of an abundance of caution. Allegheny, Beaver, Blair, Columbia, Cumberland, Huntingdon, Juniata, Luzerne, Mifflin, Northumberland, Perry, and York have been added to the quarantine for 2020.

The PA Department of Agriculture added Japanese Barberry, or Berberis thunbergii, to a list of noxious weeds — plants that cannot be legally sold or cultivated in the state. The popular, non-native, ornamental shrub forms dense, prickly thickets that crowd out plants and disrupt native ecosystems. It is also thought to harbor black-legged ticks that spread lyme disease. The ban on sale and cultivation took effect October 8, 2021. Enforcement of the ban will be phased in over two years to allow time for nurseries to eliminate it from their stock, find non-harmful alternatives, and develop seedless, sterile varieties that pose less threat to the environment and agriculture. Landscape and nursery businesses will receive notices of the timeline, procedures and exemption process for sterile varieties. Property owners should consider eliminating the shrubs on their land.
Effective October 8, 2021, the department added two other plants to the noxious weed list: garlic mustard, Alliaria petiolata, and Japanese stiltgrass, Microstegium vimineum. These plants are generally not sold in nurseries but are invasive and common in Pennsylvania. Landowners with these plants on their property are encouraged to remove them.
Kansas Department of Agriculture.
Thousand Cankers poses a serious threat to the health of black walnut trees. The Kansas Department of Agriculture, Kansas Forest Service and K-State Research and Extension need your help to help stop the introduction, and to limit the spread, of this disease in Kansas. We are deeply concerned that if it reaches the native range of black walnuts in central and eastern Kansas, we may lose this tree in our urban and native forests.

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
