Emerald Ash Borer

Last week, a UPS truck rolled up to an office of the Division of Forests and Lands. Its cargo? A cooler full of Asian wasps from a lab in Michigan.

Molly Heuss, who works on the state’s emerald ash borer program, cuts off the packing tape that holds the cooler shut to check out its contents.

New Hampshire has expanded its firewood quarantine to Rockingham County and Hillsborough County east of interstate 293, after discovering an invasive beetle in Salem.

The Emerald Ash Borer – which has decimated ash trees in the mid-west – was discovered in traps mounted less than a mile from an infestation just south of the New Hampshire-Massachusetts border, in North Andover.

New Hampshire's forest rangers are cautioning visitors to this weekend's NASCAR race: If you're camping, buy the firewood locally or have a certificate showing it's been heat-treated.

They're trying to slow the spread of the emerald ash borer, an invasive species that has destroyed millions of ash trees over the past decade. It's been found in some areas of New Hampshire.

Rangers will inspect firewood coming into New Hampshire Motor Speedway from July 9-11. The campground at the speedway is the largest in the state and the race attracts more than 100,000 fans.

The University of New Hampshire's Cooperative Extension is going on the road to educate people about the destructive emerald ash borer.  Workshops are scheduled in Canterbury at 6:30 p.m. Thursday, June 19, and at 4 p.m. Friday, June 20. Each will last two hours.  Homeowners, landowners and community leaders will learn about the beetle that has been spreading outward from Michigan for more than a decade, destroying millions of ash trees. They've been found in parts of New Hampshire.   The first workshop, at Canterbury Town Hall, will give an overview of the insect and the local situation.

While frigid temperatures don’t feel particularly great, they do play an important role in the state’s ecosystem.

One way that cold temperatures can be helpful is by beating back the wave of invasive insects that have laid siege to the state’s forests, but State Entomologist Piera Siegert tells NHPR’s Brady Carlson that the some of the recent headlines about the impact of this cold on invasive bugs over-state the case in the Granite state.

A survey is now underway in Concord, to determine how far an infestation of invasive beetles has spread. The Emerald Ash Borer has been detected in trees up and down the Merrimack River in Concord. But so far the survey has not found any of the pests outside of a six-mile radius of the city.

There are 25 million ash trees in New Hampshire, found mostly in western and Northern counties. They make up about 6 percent of the state’s forests. But so far, the beetle that has decimated forests in the Midwest, has only been discovered in and around Concord

Merrimack county is under quarantine. Emerald Ash Borer, an invasive Asian beetle that has killed millions of Ash trees in the Midwest, has been discovered in Concord.

Once the beetle’s population has been established, they can spread incredibly fast, doubling every year. Today the state learned where the patient zero of the New Hampshire infestation can be found.

The January issue of Atlantic Monthly online reported a curious connection between the death of 100 million ash trees killed after the arrival of the invasive, exotic “Emerald Ash borer” beetle in lower Michigan to an ensuing spike in rates of human heart disease and pulmonary illness including pneumonia.

The Emerald Ash Borer, an invasive Asian beetle that has killed millions of Ash trees in the Great Lakes region, is creeping closer to New Hampshire.

This week an Emerald Ash Borer infestation was found in the Berkshires in Western Massachusetts. The pest has spread from Michigan, through the Mid-Atlantic region, to upstate New York and Connecticut.

Kyle Lombard with the division of Forested Lands says, on its own the ash borer moves very slowly.

Fear of the Beetle

May 10, 2012

New Hampshire foresters are closely watching the movements of an exotic beetle known as the Emerald Ash Borer.  Just last month the U-S Forest Service announced that for the first time, the beetle has been found east of the Hudson river.  That’s just ninety miles from the New Hampshire border.  The Emerald Ash Borer first appeared in North America ten years ago, and has killed millions of ash trees in several mid-Atlantic and Midwestern states, as well as Canada.  To find out whether or not the beetle poses a threat to the Granite State, we turn to Kyle Lombard.  He’s the Forest Health Prog
