Forests in the Nation's most densely forested and most densely populated region will change radically in the next 50 years, primarily because of the way they are managed -- or not managed -- today, according to a new report by a team of USDA Forest Service scientists and partners.
"This research is vital to everyone concerned about sustaining diverse, healthy, productive forests and the associated ecosystem services, commodities, and jobs our forests provide," said Tony Ferguson, Acting Director of the Northern Research Station and the Forest Products Laboratory. "It provides a scientific foundation for exploring and discussing the future of forests, and it underscores the role of management in making forests healthier and more resilient."
Future Forests of the Northern United States is part of the Northern Forest Futures Project, a cooperative effort of the Forest Service, the Northeastern Area Association of State Foresters and the academic community. Begun in 2009, the project examines how past trends and today's choices may impact Northern forests in coming decades.
The new report is published as General Technical Report NRS-151 by the Forest Service's Northern Research Station and is available online at: http://www.
Change is nothing new to Northern forests, and much of it has been positive over the past century. Since the early 1900s, a period when forests were exploitively logged and cleared for farms, there has been an increase of 11 million acres of forest land and an increase of 144 million cubic feet of timber, both despite a population increase of 26 million people.
However, other changes are causing concern for forest owners and managers: the expanding impact of invasive species, loss of species diversity, low diversity in forest age classes, increasing urban expansion that is shrinking forest acreage, fragmentation of forest land, parcellation of forest ownerships, loss of forest-based employment, effects of burgeoning white-tailed populations on tree regeneration and forest composition, and increasing atmospheric carbon emissions.
"The challenges facing northern forests are large, complicated, intertwined, and enduring," said Stephen Shifley, one of the 30 authors who collaborated on Future Forests of the Northern United States and a principle investigator for the Northern Forest Futures project.
"By applying the best available science to look ahead at how forests are likely to change over the next 50 years, we think forest owners, managers, planners, and policymakers will be better prepared to avoid many future problems by implementing proactive management practices that are ecologically sound, socially acceptable and economically viable."
A few of the trends that will affect Northern forests over the next 50 years include:
Future Forests of the Northern United States is one of a series of publications examining past, present and anticipated changes in forest biodiversity, productivity, health, soil and water, carbon, biomass, energy, commodities, employment, and recreation in the U.S. North.

The mission of the Forest Service's Northern Research Station is to improve people's lives and help sustain the natural resources in the Northeast and Midwest through leading-edge science and effective information delivery.
The mission of the Forest Service, part of the U.S. Department of Agriculture, is to sustain the health, diversity, and productivity of the Nation's forests and grasslands to meet the needs of present and future generations. The agency manages 193 million acres of public land, provides assistance to state and private landowners, and maintains the largest forestry research organization in the world. Public lands the Forest Service manages contribute more than $13 billion to the economy each year through visitor spending alone. Those same lands provide 20 percent of the Nation's clean water supply, a value estimated at $7.2 billion per year. The agency has either a direct or indirect role in stewardship of about 80 percent of the 850 million forested acres within the U.S., of which 100 million acres are urban forests where most Americans live.

New 3-D model predicts best planting practices for farmers

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
