USDA APHIS is proposing to end the federal emerald ash borer (EAB) quarantine. As indicated in the announcement below, USDA is taking comments on the proposed “deregulation”.

Hydrilla, touted as the worst aquatic invasive species, was recently found in a waterbody that is hydrologically connected to Vermont in the Connecticut River. As part of an Early Detection and Rapid Response, VTDEC staff joined state biologists from Connecticut, Massachusetts, and New Hampshire to sample sections of the river in Connecticut to survey the extent of the infestation.  

The USDA Animal and Plant Health Inspection Service has confirmed that insects collected from ash trees in South Hero, VT are larvae of the emerald ash borer (EAB). This location is about fifty miles from the closest confirmed EAB infestation in Vermont. This invasive insect was first discovered in Vermont in February, and has also been confirmed in Orange, Washington, Caledonia, and Bennington counties.

European spindle tree (Euonymus europaeus) is a member of the spindle tree family (Celastraceae), which includes species that are also invasive to North America like burning bush (Euonymus alatus) and Asiatic bittersweet (Celastrus orbiculatus). Species within the spindle tree family are woody shrubs or woody vines, all which have brightly colored flesh (arils) around the seeds ranging from reds to oranges. These fruits appear on the European spindle tree in the late summer and early fall.

Zebra mussels have been confirmed in the Canadian waters of Lake Memphremagog.

If you’ve ever spent a late August afternoon along a lake with a reedy shoreline, you may have noticed the brilliant, beautiful purple flowers of this month’s focal plant: purple loosestrife (Lythrum salicaria).

In mid-summer, Vermont starts to see a wave of yellow flowers bloom along roads, fields, meadows, and trails. This plant is called Wild Parsnip (Pastinaca sativa) and is similar in appearance to Queen Ann’s Lace (Daucus carota). Wild Parsnip is a member of the carrot family (Apiaceae), and is currently considered taxonomically indistinct from the common garden parsnip.

Officials say the invasive pest the emerald ash borer has been found in the southern Vermont town of Stamford. The location is within five miles of a location in North Adams, Massachusetts, where the insect was also recently discovered.

Biological control of purple loosestrife is being attempted in Pa. wetlands.

The invasive emerald ash borer has been found in Montpelier. City officials are taking steps to protect some trees along city streets, but ultimately they say most of Montpelier’s ash trees will die.
