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.

The invasive tree-killer that’s alarming Vermont forestry officials could cost the town of Hartford alone hundreds of thousands of dollars, according to early projections by Tree Warden Brad Goedkoop.

The Vermont Agency of Natural Resources is poised to combat the spread of aquatic invasive species this summer.

There are at least 50 species of non-native insects established in the state, including the Emerald Ash Borer, which has devastated the local ash tree population. Poised to join this list is another wood-boring bug, which could have a similar impact on more of New Hampshire’s trees: the Southern Pine Beetle.

Officials at the Maine Department of Agriculture, Conservation and Forestry (DACF) report that emerald ash borer (EAB) has been found in Maine. Despite an aggressive search for at least a decade, the destructive forest insect from Asia had not been detected in Maine previously. It has killed hundreds of millions of ash trees in thirty-four states throughout the country. The estimated commercial (unprocessed) value of Maine ash trees is approximately $320 million.

After years trying to stop the spread across state lines of an invasive beetle that destroys trees, the federal government looks about ready to give up.

The Department of Agriculture will soon propose abandoning an emerald ash borer quarantine that restricts the movement of firewood and items from ash trees, putting new emphasis on biological controls and other approaches that don't require federal regulations and, the agency said, may be more effective.

Training dates for this year's Vermont Invasive Patroller trainings, hosted by the Vermont Department of Environmental Conservation, have been set.

Motorists in the areas of Plainfield, Groton, Calais, Williamstown, Washington, and Barre may notice new flashing road signs reading “Don’t move ash firewood beyond this point.” The signs are part of an inter-agency partnership to slow the spread of the Emerald Ash Borer, which has been detected in the vicinity.  Signs are located on state highways and are visible to motorists leaving the EAB-infested areas.

As part of the ongoing response to the recent discovery of the Emerald Ash Borer (EAB) within the state, Vermont has joined the United States Department of Agriculture (USDA)’s 31-state quarantine boundary. The quarantine will help reduce the movement of infested ash wood to un-infested regions outside of Vermont’s borders. Ash wood may not be moved from Vermont to Maine, Rhode Island, or 5 counties in New Hampshire because the pest has not been identified in these states and counties. Vermont will be directing available resources to protect state forest health by providing Vermonters with low-risk options for use and disposal of wood that is already infested.
