Invasive Callery pear (Pyrus calleryana and all its cultivated varieties) has been in the news this year; states across the region have been listing this species as a noxious weed – a distinction that carries with it limitations and regulations on the sale and movement of these plants.
In mid-August, a concerned community member brought to the attention of scientists, the presence of an invasive insect. The insect, spotted lanternfly, had never been reported before in Vermont, and was first detected in the United States in 2014 in Pennsylvania, but has spread across the eastern US to 8 states.
In our last issue of the VTInvasives e-newsletter, we discussed a new method of treating knotweed by using wire fencing laid horizontally on the ground over a patch of the offending species. Over the past two months, I have received several emails from readers asking some clarifying questions and looking for updates. I apologize for not being able to reply to everyone, and I hope that this article can provide an update with some answers.
The colder temps and flurries of snow may make plant identification a thing of dreams for the coming summer. But one common invasive plant in Vermont can still be easily spotted throughout the winter months: common buckthorn.
It is hard to believe that the Forest Hero! Network is fast approaching its 1st birthday! To celebrate, we'd like to share with everyone, the good work that volunteers are completing in their communities. If you are working on a project and would like to help inspire others who may be seeking ideas, please write in and we'll share in future newsletters!
Amur Maple, Acer ginnala, belongs to the Sapindaceae family, which now includes previous members of Aceraceae (maple family). It is native to northern China and Japan, and was introduced into North America in 1860. Beginning in the 1950s, Amur Maple was reported as “locally established”.
When recalling a drive down a dusty country road, you might remember seeing round green shrubs speckled with small white flowers, in otherwise empty grazing paddocks, or along farm fields. This plant is called multiflora rose (Rosa multiflora) and is a perennial shrub within the Rose family, Rosaceae. The name, multiflora, means “many flowered”, and its nickname, “rambler rose” perhaps comes from its tendency to spread from cane or seed.
The 2018 Vermont Habitat Stamp Annual Report, released earlier this winter, highlights the conservation power of the multiplier effect – where one action can be a catalyst for other actions and the effects keep radiating out. This past year, over $110,000 were raised from donations and were then used to leverage an additional $143,000 in federal funds. This created a total reserve of over $253,000 to be used for habitat conservation by the Vermont Department of Fish and Wildlife.
The growing season for 2018 saw many projects across the state tackling the forest, field, and wetland health issue of non-native invasive plants. Below are highlights of some of these amazing local efforts. Huge thanks to everyone who is working toward making our Vermont landscapes healthier and more resilient, and protecting them for generations to come.
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.
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.
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.
