Researchers with the University of New Hampshire are taking to the skies to study the state's increasingly fragmented forests.
Urban and agricultural growth, and roads are carving up large swaths of forestland into smaller patches, exposing new forest edges to invasive species and uprooting wildlife.
Russ Congalton, professor of natural resources and the environment at the University of New Hampshire, said they're using drones to get a better look at how forests are responding.
"So we could see 50 meters into the forest," Congalton suggested. "There's still a change in the vegetation, there's still a change in the density of the vegetation, there probably are some temperature changes."
Congalton pointed out newly-created forest edges affect tree mortality, which increases carbon emissions contributing to climate change. They are also more susceptible to invasive species, like the woolly adelgid, attacking hemlock trees across New England.
New Hampshire lost more than 126,000 acres of forest from 1983 to 2017, a nearly 3% reduction, according to the U.S. Forest Service.
Congalton noted by using drones, researchers can view nearly 100 acres of forest in 40 minutes, helping them not only cover more distance, but detect and measure the forest's adjustment at the new "edges" sooner.
"We save tons of effort, tons of money and tons of time in order to get this kind of information in a lot more efficient and effective manner," Congalton explained.
Congalton added some residents have at times not been happy about seeing drones near their property, but he hopes they know the camera is focused on the trees, and there are a lot of them. At nearly 80% forest coverage, New Hampshire ranks as the second most-forested state in the U.S.

New research shows ancient chili peppers were likely growing in Southwestern states like New Mexico millions of years earlier than previously thought.
Scientists believe birds - which, unlike people, lack heat receptors and don't wince, or worse - when eating the spicy "berry-like" fruits, and spread their seeds across vast areas.
Now, researchers at the University of Colorado say a previously collected fossil shows they were growing in the Americas as much as 50 million years ago - much earlier than the 15 million years ago previously thought.
Study senior author, Stacey Smith - an associate professor in the Department of Ecology and Evolutionary Biology - said finding a fossil that upends settled facts is unexpected.
"All of these sort of distinctive members of the family made of eggplants, chile peppers, tobacco," said Smith, "all of these were around long, long before humans ever encountered them. So they were sort of hanging out waiting for us."
As of March 2023, "roasting green chile" is now the official scent of New Mexico. Lawmakers approved and the governor signed a bill making it the first state in the country with an official aroma.
It's estimated the Land of Enchantment produced a whopping 53,000 tons of the peppers in 2022.
Researchers say the chile-pepper fossils originally were collected from the Green River Formation in northwestern Colorado. The findings challenge the previous scientific understanding that nightshades originated from South America.
Smith said she's a bit awed and happy she's able to relate how the fossil discovery has transformed her understanding of plant diversification.
"'Oh that's a fossil of that kind of lizard' or 'That's a fossil of this kind of plant,'" said Smith. "So, it just so happens that we are the people who study those kind of plants and we look at that fossil and say, 'Hey, that's a chile pepper' - and we're 100% certain that it's nothing else."
The findings were recently published in New Phytologist, noting the entire nightshade family - including peppers, tomatoes, potatoes and more - is much older and was more widespread than previously documented.

A U.S. Supreme Court case that began in Idaho has weakened protections across the nation under the Clean Water Act.
The justices on Thursday handed down a 5-4 decision that will undo federal safeguards for wetlands. The case stems from a couple's attempt to build a house in Priest Lake, Idaho. The Environmental Protection Agency informed the couple that backfilling on the property violated the Clean Water Act because it was affecting sensitive wetland habitat. The couple sued the agency.
Alex Funk, director of water resources and senior counsel for the Theodore Roosevelt Conservation Partnership, said the decision is a blow in many respects, including to people who enjoy the outdoors.
"For the hunting, fishing and sporting, and even kind of the broader outdoor rec community," he said, "these wetlands provide so many public values that are now at significant risk from development and other impacts."
In its decision, the majority wrote that Clean Water Act protections extend only to wetlands "indistinguishable" from larger bodies of water. It could affect up to 90 million acres of wetlands across the country.
Funk said wetlands are vital ecosystems providing benefits that tend to go unrecognized.
"If anything," he said, "this is going to put major setbacks on things like our ability to adapt to climate change, respond to extreme weather events, drought."
He noted that these habitats are essential for clean water, flood mitigation and storing carbon. Wetlands cover 386,000 acres in Idaho, according to the U.S. Geological Survey.

For the first time in nearly three years, the widespread drought that has had Iowa in its grip is predicted to end. The latest drought outlook says the tinder-dry weather pattern will lift later this year.
The last time no part of Iowa was abnormally dry was in April 2020, according to the federal Climate Prediction Center's latest seasonal outlook. Justin Glisan, Iowa's state climatologist, said much wetter-than-normal spring weather, including the severe weather events that came with it, will kickstart the state's long climb back from the drought.
"Three years of precipitation deficits stacking up to 25 inches below average," he said. "We've started to put a dent in those longer-term deficits. We're seeing improvement, and contraction of the drought region."
May and June are normally Iowa's wettest months, and Glisan said the precipitation is still "ramping up." He added that this will be good for farmers who are planting crops and can look forward to more moisture than they've had recently.
Parts of Iowa have seen rainfall up to 6 inches above normal recently. Glisan said it's being driven by the El Niño weather pattern that is expected to intensify in the coming weeks. El Niño results from warmer-than-normal Pacific Ocean temperatures near the equator, and causes more rain in the Midwest. That's a positive for farmers, he said, as opposed to the La Niña pattern, which creates drier conditions in the region.
"We're moving in the right direction, trend-wise, in terms of the large-scale atmospheric setup that would support more rainfall during the growing season," he said, "as opposed to those La Nina signals that we had for the last three years."
Ironically, despite the pervasive drought, Iowa corn yield averages in the past two years have been among the state's highest in history.
