Invasive Plants Other Insects reported in our area
Rain Gardens Native Plants Sustainable Woodstock Dartmouth Organic Farm BooksAlerts We need your help You can play a vital role in preserving the health of our forests. These alerts are for the Asian Longhorned Beetle, Emerald Ash Borer and the Hemlock Woolly Adelgid Destructive non-native forest insects such as the Emerald Ash Borer and the Asian Longhorned Beetle have found their way into the United States and are now "hitchhiking" from state to state in firewood and nursery stock. In addition, the Hemlock Woolly Adelgid has arrived in Vermont. These insects are capable of completely changing our forests by devastating various native species - ash, maple, birch, hemlock :
Early detection is crucial to minimizing the damage and maximizing the opportunities available for management of these invasives. Most discoveries of invasive insects are made by informed citizens - not the professionals.
Vermont Division of Forestry: http://www.vtfpr.org/Firewood/index.cfm Emerald Ash Borer Source: Vermont Division of Forestry The Emerald Ash Borer is an exotic, wood-boring insect from Asia that attacks and kills all native ash species. It is metallic green and the adult beetles are present from mid-May to late-July. The
larvae feed in the cambium between the bark and the wood, producing
S-shaped galleries that girdle and kill branches and trees. Ash is one
of the most common trees in Vermont, so this insect will have a major
impact if it becomes established in Vermont. Please
inspect your trees. If you think you might have EAB in your trees, have
questions about the program or quarantines- please call
The symptoms include: (photos below)
D-shaped adult emergence holes Branch & crown dieback Epicormic branching around the trunk
under the bark Also: Emerald Ash Borer http://www.vtfpr.org/protection/eabupdate.cfm ____________________ Asian Longhorned Beetle
The
Asian longhorned beetle (Anoplophora glabripennis) a pest of hardwood
trees including maple, birch and horse chestnut, was recently
discovered in Worcester, Massachusetts. It is an invasive species -native to China-that causes damage by tunneling
within the trunks and branches of trees, disrupting the sap flow and
weakening and eventually killing them. It is considered a serious threat to the nursery, lumber, maple syrup, and tourism industries in our state.

Hemlock Woolly Adelgid is infesting Vermont's beautiful hemlock trees. The HWA is a non-native insect that damages and
kills forest and ornamental hemlock trees. In 2007 the HWA was found on
mature, native trees in southern Vermont.. Since infestation can be most easily
spotted this time of year, please inspect your hemlocks. Remove bird feeders between March and July,
when HWAs can move to new areas on birds. Removal will have minimal
impact on the birds since spring food sources are becoming available,
but may be effective in slowing the spread of HWA. What to look for: The most obvious sign of HWA is a white, woolly mass found on the underside of twigs at the base of the needles. The masses look like the tips of cotton swabs. More established infestations may have thinning branches and grayish-green needles. If you think you find an infestation of HWA, do not remove any material from the site. Instead, take good notes about the exact location and
The VT Dept. of Forestry, Parks and Recreations has begun to take the offensive by releasing Laricobius - a predatory beetle that feeds almost exclusively on hemlock wooley adelgid.

Native Plants Native plants are those plants that grew in New England before the arrival of European settlers. Many of the plants you have in your landscape are probably native and you don't even know it. Native plants, as a group, are part of what makes New England unique. In addition, native plant communities provide a vital habitat for New England's wildlife.
