New Study: Nitrogen Pollution Hinders Forest Decomposers

Process of taking soil sampling.

Atmospheric pollution may be altering forest ecosystems in ways that are difficult to reverse, according to a study of experimental Harvard Forest soils recently published in the journal Ecology, led by a team of HF collaborators from the University of New Hampshire, University of Wyoming, and University of Wisconsin-Madison.

New Insights on Changing Hemlock Forests

Three recent studies co-authored by Harvard Forest ecologist David Orwig detail the impacts of the invasive hemlock woolly adelgid (HWA) on forests, carbon, and the New England economy.

In a paper published in Southeastern Naturalist, researchers estimated the financial loss caused by the decline of hemlock trees in a 2,800-square-mile area across 9 counties in central Connecticut and

New SPE Study: Power Plant Standards and Public Health

Carbon Co-Benefits study

On June 2, 2014, the EPA released the nation’s first-ever carbon pollution standards for existing power plants. Released today is part 2 of a 3-part study, in which Science Policy Exchange researchers analyze the impact of different policy options for power plant carbon standards on clean air and public health. 

"Health Co-Benefits of Carbon Pollution Standards for

Long-Term Insights on Soil Carbon

Harvard Forest DIRT plot

Unraveling the complex functions of the soil ecosystem has been a research focus at the Harvard Forest for over 20 years. Results from our Detritus Input Removal Treatment (DIRT) experiment were highlighted this month by the Soil Science Society of America.

Soils are a globally important reservoir of carbon, containing three times more carbon than the

New SPE Study: Rules on Carbon Emissions Benefit People & the Environment

Annual sulfur deposition in 2020

On June 2, the EPA released the nation’s first-ever carbon pollution standards for existing power plants. In a new report by the Science Policy Exchange, scientists from Syracuse and Harvard analyze how and where that rule will improve local air quality, decrease atmospheric deposition, and benefit people and ecosystems across the U.S.

The authors of the study, including

Bullard Spotlight: Pamela Templer and Winter Climate Change

Pamela Templer

This year, a new highlight series will showcase research by Harvard Forest's Charles Bullard Fellows, who come to the Forest for up to a year to contribute, either as scholars or administrators, to forestry defined in its broadest sense as the human use and study of forested environments.

This month, we're highlighting Pamela Templer, who is spending 2013-2014 jointly as

Results from a Long-term Study of Hemlock Loss

Hemlock at Harvard Forest

Eastern hemlock, a foundation species common in many local forest stands, is disappearing from the southern New England landscape. Its loss is due in part to the invasive hemlock woolly adelgid, and in part to pre-emptive logging. A large-scale experiment at the Harvard Forest has tracked the ecosystem impacts of adelgid invasion (simulated by tree girdling) and commercial

Defense Department Supports New Ecosystem Research

Garlic Mustard

The US Department of Defense (DoD) has granted $2 million to Harvard Forest researchers Kristina Stinson (UMass Amherst) and Serita Frey (UNH) for a five-year study of how soil microbial communities respond to major ecosystem change.

Soil fungi are crucial to the growth of many native trees, but their functions can be easily disrupted by the belowground

21st Annual Harvard Forest Ecology Symposium

Climbing Tower

The tweny first annual Harvard Forest Ecology Symposium will be held March 16, 2010 from 9:00am - 5:00pm at the Harvard Forest. This year's symposium will feature talks and discussion:

  • Future directions and integration of atmospheric (tower-based), terrestrial and aquatic measurements, including anticipating the establishment of a 35-ha forest dynamics plot
  • Emerging results and synthesis of studies on foundation species from
