Vermont Invasives.

An emerald ash borer (EAB) beetle was detected in a tree located in Londonderry, VT. The mapped area in Vermont (PDF | 1.25 MB) to which "Slow-the-Spread" recommendations apply now covers:

  • All of Londonderry, Windham, and Landgrove;
  • Most of Jamaica, Winhall, Peru, Weston, Andover and Grafton; and
  • Extends into Chester, Townshend, Stratton, Athens, Mount Tabor, and Wardsboro.

October means that non-flight season Recommendations to Slow the Spread of Emerald Ash Borer are now in effect when moving ash from the infested area. With the heating season underway, and firewood deliveries actively occurring, it’s important to remember that untreated ash firewood should never move out of infested areas. Be sure that your purchase or transportation of both log length and split firewood will not unnecessarily spread EAB. There’s a lot of spread to slow: While the infested area map shows that high-risk areas for EAB include many towns, visibly infested trees still remain rare in Vermont. You can help by following the "Slow-the-Spread" recommendations.

These plants are known to be invasive or potentially invasive in Connecticut and are on Connecticut's list of Invasive and Potentially Invasive Plants. They are known to be present only in relatively low numbers at limited locations in Connecticut. These species should be considered for control and eradication efforts in the state when resources are available. If you find these species: Report your findings immediately to the CT Invasive Plant Coordinator at reportinvasives@uconn.edu.

This guide is intended to assist with identification of invasive plants and provide information on controlling these problem plants. Included are both non-chemical means of control as well as information on proper use of herbicides where chemical controls are needed. The choice of control measure depends on the size and nature of the infestation. If dealt with early enough, invasive plant problems can often be eliminated by non-chemical methods. However, a herbicide-based approach may be required to control an infestation that has become well established or widespread.

The Asian Longhorned Beetle (ALB) was found in Worcester, MA in August 2008 and in Boston in July 2010. This insect pest poses a serious risk to trees and forests. ALB has not yet been found in New Hampshire. Help us by looking at the debris from your swimming pools. Whenever you clean your pool, look at the debris you collect in your filter and skimmers. Use this fact sheet (PDF | 1.22 MB) to compare collected insects to common insects. Upload pictures of any insect you think is a longhorned beetle.
