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.

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.
