N.H. is home to an international alarm system made of trees – The Boston Globe
The so-called sentinel gardens spanned three continents and four countries, including Sweden, China, Italy, and the United States. New Hampshire is home to one of two sentinel gardens in the US. The other is located at the Waterman Farm on the Ohio State University Campus in Columbus, Ohio.
Researchers involved in the project hoped to make new discoveries about which insects and pathogens harm different plants.
Isabel Munck, a plant pathologist for the US Forest Service who works in Durham, N.H., was among them.
“One of the biggest threats, if not the biggest threat to our forest in this part of the world are invasives, like pathogens and insects,” said Munck.
If the researchers noticed a tree struggling, they could investigate which pathogens or pests were likely to blame.
Foreign invasives can hitch a ride into the US in wood products, packing materials, or on live plants imported by nurseries, for example. But native plants haven’t developed any resistance to those insects or diseases, which means they can be especially damaging or even lethal.
Munck said she was especially interested in learning more about fungi, which make up most forest pathogens.
“The point of this project is to try to detect them before they spread,” Munck said. She likened the trees planted abroad to a canary in a coal mine, capable of alerting people to a problem before it becomes lethal.
She worked on one of the sentinel gardens, located at the Urban Forestry Center in Portsmouth, N.H., where plants from China and Europe were grown.
Gardeners in Italy, Sweden, and China reciprocated by growing plants from New Hampshire in those three countries to see how they would respond to pathogens located in those countries.
Researchers in China found several new pathogens that impact red maple that had never been reported before, according to Munck.
These observations could be used to inform policy decisions about monitoring and preventing harmful pathogens from entering the country to protect forests.
“We’re not going to stop international commerce and movement of goods and services and people. It’s an attempt to not be surprised by things that have surprised us in the past,” said Pierluigi Bonello, a plant pathology professor at The Ohio State University. Bonello also directed the sentinel garden research project.
“This is just step zero, not even step one, just to see what’s out there,” he said. “Once you know there is a potential threat, theoretically then, you can alert the border inspection facilities in the United States, for example, to be on the lookout for that specific organism.”
When invasive species go undetected, they can create big problems.
Beech leaf disease is one of the top concerns Munck sees in the region today, caused by nematodes, or microscopic worms, that are believed to come from the Pacific Rim. First detected in the US in 2012, it prevents beech trees from developing shoots so the trees stop making new leaves. It has been found in 13 states so far, including New Hampshire, Massachusetts, Connecticut, Rhode Island, and Maine.
Scientists are concerned about the rate of spread, and that the invasive can kill trees just a few years after symptoms first show up.
Munck is also studying trees at the Arnold Arboretum of Harvard University to see what kinds of fungi are already present here. The 281-acre arboretum has over 16,000 trees, including species from all over the world. Some of the same species that grow in the arboretum were planted in the sentinel gardens around the world, so Munck can compare the fungi present in Boston to those in Jiangsu Province in China, for example.
“We’re trying to exclude the things that are always present from the ones that are causing disease,” Munck said.

Nashua man dies after car crash and fire on Route 101 in Candia, investigation ongoing
CANDIA, NH (WGME) – Early Monday morning, a Nashua man died following a crash on Route 101 eastbound in Candia, New Hampshire.
Joseph H. Lavoie, 58, of Nashua, had been driving along Route 101 eastbound near Exit 3 when he lost control of his car, resulting in a drift off the right side of the highway before striking the cement bridge at the Old Candia Road overpass.
State troopers arrived at the scene to find Lavoie’s car on fire, though several passing drivers had helped to pull Lavoie out of his car. The fire was quickly extinguished.
Lavoie was taken to the hospital where he later died from his injuries.

New Hampshire’s Energy Landscape in 2025 – Concord Monitor
The biggest national news in 2025 often involved energy — how to make it, who gets to use it, who is going to need it. New Hampshire has sidestepped most of those questions so far but still saw plenty of energy news.
Goodbye, coal
The closing of the Merrimack Station power plant in Bow sounds like New Hampshire’s biggest energy news of the year and got a lot of national coverage along the lines of “New England shuts down coal!” but to be honest, it didn’t make much difference. The plant had been winding down for years, having run for fewer than 30 days in 2024, and would almost certainly have shut in a year or so because it lost what is known as capacity funding.
The more interesting question is what will replace it. Granite Shore Power President Jim Andrews has long touted plans to turn Merrimack Station, as well as the long-closed Schiller site in Portsmouth, into 21st century power plants using batteries and solar power, with perhaps some offshore wind assembly on the shores of the Piscataqua River.
But Donald Trump was elected and promptly began to trash wind and solar power, yanking subsidies and throwing up regulatory roadblocks. Granite Shore now says it is looking at all possibilities.
Both sites have excellent connections to the power grid, which makes them very valuable.
We need more electricity
New Hampshire, like New England in general, have not been swamped with proposals to build massive, power-hungry data centers for bitcoin mining and artificial intelligence. Those proposals have led to forecasts that national demand for electricity will spike by a quarter or more within a few years.
ISO-New England, the group that runs the six-state power grid, projects an 11% increase in electricity demand over the next decade, largely driven by the electrification of heating and transportation. That’s a lot, especially after years of stagnant demand, but it’s not panic-inducing.
Sidestepping regulation
New Hampshire is set to become the first state to allow energy providers to skip most utility regulation if they don’t connect to the grid. Supporters say it adds much-needed flexibility to the hidebound energy industry while critics call it a sop to very large energy users, such as data centers. It’s not clear how much it will be used, but it’s an interesting experiment, at least.
Community solar OK, wind not so much
The Republican-controlled legislature isn’t quite as anti-solar power as President Trump but it shows a lack of enthusiasm for renewable energy. They passed a bill loosening stormwater runoff rules for solar arrays but tightened the Renewable Energy Fund and as the year ended, they were looking to make severe changes to the Renewable Energy Portfolio.
On the other hand, there’s community solar. Thanks to a series of bills over the past few years, arrays up to 5 megawatts can share production with multiple customers, making big projects that opened or are being built in Exeter, Bedford, Derry, Warner and now Concord financially feasible. It seems likely that 2026 will set a record for the most solar added to the grid in New Hampshire. If the legislature would let private companies be community-solar customers, we’d do even better.
As for wind power, legislators echoed Trump’d hatred of the industry. Gov. Ayotte agreed to shorten the name of the Office of Offshore Wind Industry Development and Energy Innovation to simply the Office of Energy Innovation as part of removing virtually all support for wind power on land or in the sea. Not that we gave much support to begin with.
Ironically, this month saw New England receive a record amount of power from wind turbines — more than 1,600 megawatts at one point — as the Vineyard Wind offshore farm finally got up to speed.
What about natural gas? Nuclear? Heating oil?
As has been the case for many years, natural gas was the fuel to supply about half of New England’s electricity in 2025 and heating to about one-fifth of New Hampshire’s homes.
Many politicians are making noises about building more pipelines to bring in more natural gas from New York or Pennsylvania; Gov. Ayotte expressed support for bringing the proposed Constitution Pipeline, which was killed in 2020, back to life. Many argue that such work would be prohibitively expensive and make the region even more dependent on a single type of fuel.
Natural gas has traditionally been very cheap compared to other types of fuel but its price is increasingly affected by global patterns because of an increase in exports.
A separate question is whether the push to electrify the region’s heating can cut into our use of heating oil. Northern New England is by far the national leader in using that dirty fuel for heating; switching to electric heat pumps is almost always cheaper and definitely cleaner. New Hampshire is one of five states in the New England Heat Pump Accelerator, which looks to spend $450 million from Joe Biden’s 2022 Inflation Reduction Act to encourage more heat pumps.

FAA investigating after small plane crashes into New Hampshire condominiums
NASHUA, N.H. (AP) — A pilot was taken to the hospital with injuries Wednesday after a small plane crashed into a residential neighborhood in southern New Hampshire, authorities said.
Emergency crews found the aircraft upside down in a snow bank in the parking lot of a wooded condominium complex in Nashua Wednesday afternoon.
Police said the pilot was the only person on board and was the only person injured. The Federal Aviation Administration is investigating.
The Velocity V-Twin plane crashed at the Cannongate Condominiums shortly after departing from the nearby Nashua Airport around 2:10 p.m. local time, according to the FAA.
Aerial video from NBC10 Boston showed damage to the roof of one of the condos near the crash site.
