Invasives in the News

November 7, 2018

These grants will support efforts to prepare for and manage the impacts of emerald ash borer (EAB). EAB is a destructive and invasive forest pest that feeds on all species of ash trees, killing over 99% within four years of infestation. The state's forested land is made up of about 5% ash, yet up to 50% of downtown trees in Vermont are ash. All said, Vermont is home to an estimated 160 million ash trees. EAB is now confirmed in Orange, Washington, Caledonia, Grand Isle, and Bennington Counties. Communities statewide are encouraged to prepare to manage the decline of ash trees and the future of an urban tree canopy without ash.

Many invasive plants in Vermont start blooming in May. Keep an eye out for one obvious bloomer this time of year, Wild Chervil (Anthriscus sylvestris), or also commonly called “cow parsley”. This invasive plant can be seen alongside roads, and is notable in our rolling Vermont fields. This is a biennial herbaceous plant within the carrot family, Apiaceae. In Vermont, there are two introduced Anthriscus species documented outside of cultivation, and include Wild Chervil and its close relative, Garden Chervil (Anthriscus cerefolium). The name, Chervil, comes perhaps from Latin and Greek roots, collectively meaning “leaf to enjoy”.
