"DURHAM — After fighting the invasive glossy buckthorn for decades, Tom Lee, University of New Hampshire associate professor of forest ecology and NH Agricultural Experiment Station researcher, and Steve Eisenhaure, UNH Office of Woodlands and Natural Areas land use coordinator, have planted an entire orchard of the shrub at UNH's Kingman Farm.
Using this orchard, their team is looking...
There are five challenges that are inhibiting our forests' ability to regenerate successfully and remain a productive land use and a healthy ecosystem: Invasive species, deer, fragmentation, habitat diversity and private owner stewardship.
"There are tiny, unseeable creatures doing tiny, unseeable things to help people, wildlife and plants all around us.
Microbes are everywhere—inside the dirt, on your dog and even in your stomach. And scientists increasingly want to harness their powers for good.
One way could be to manage invasive species

SHELBURNE CENTER, Massachusetts — It was only a year ago that Norman and Lisa Davenport first noticed sunlight flickering through the once-dense shade of a stand of hemlocks on their hilltop farmland.
And now those first trees look more like utility poles than conifers.
As the twin evils of elongate hemlock scale and hemlock woolly adelgid spread...
The winter of 2014-2015 was tough on hemlock woolly adelgid; 97 to 99 percent of the sistens, or winter, generation died. The previous winter had similar winter mortality rates. This helped to give hemlock trees a bit of a reprieve. But, while these recent mortality rates have been high enough to temporarily stop the spread of HWA, the trees are still...

Vic Bogosian has an 18,000-strong army--or, rather, air-force--of wasps, and he's looking for more draftees. They're fighting an enemy of the Pokagon Band of Potawatomi, the emerald ash borer, an invasive species from China that has been wiping out an important part of Michigan's Native American culture, the ash tree.
"The bugs here yet?" the...
Mattapoisett — In 2013, at least 1,000 European flies were released into Nasketucket Bay State Reservation with the hopes that they would spread throughout the area. Awesome, right?
It may not sound like good news, but these flies have a very specific job to do: take down the winter moth population.
In 2001, ash trees began dying in Detroit, and no one could say why. Then glittering green beetles were discovered crawling out of an ash log.
American scientists had never seen the beetles, and they reached out to experts around the world for help. A Slovakian entomologist named Eduard Jendek solved the mystery: Detroit’s ash trees were being killed by Agrilus planipennis, the emerald...

Oak wilt is an aggressive and often deadly disease that affects all species of oaks (Quercus). It is one of the most serious tree diseases in the eastern United States.
Each year thousands of oaks die from this disease in yards, public landscapes and forests. It has been found in 21 states, with considerable damage occurring in...
