Carbon and Water Dynamics in a Deciduous Clearcut

A new Harvard Forest study released today in Global Change Biology provides the first detailed account of how carbon, water, and energy balances shift in the years following a clearcut of a broadleaf temperate forest.

Results show a steady loss of carbon dioxide to the atmosphere from the clearcut area, primarily from exposed soils and decaying wood. The cleared area will only become a significant "sink" for atmospheric carbon after a decade or more of regrowth.

New Study: Carbon Age in Sprouting Trees

A comparative study of red maple trees at the Harvard Forest and at Bartlett Experimental Forest in New Hampshire sheds new light on how trees allocate carbon throughout their life cycle--including just after they have been cut. The researchers used radiocarbon dating to "age" the carbon in new sprouts that emerge from stumps when trees are harvested.

Change and Resilience in Northeast Forests

Slab City: 1890 and today

A joint Harvard Forest-Smithsonian study released today in PLOS ONE compares modern forests to their pre-colonial condition in a 9-state analysis of Northeastern forest change. More than 300,000 colonial-era "witness tree" records--never before analyzed at this scale--reveal that although the same types of trees are present today, the number and locations of these trees are dramatically different.

It's the Network: Decision-Making by Forest Landowners

Students interview landowners, 2012

A recent study led by Harvard Forest Policy Analyst David Kittredge reveals surprising trends in how private landowners--whose small holdings comprise the majority of forests in the eastern U.S.--make decisions about their land.

New Study: Small Streams Transport Key Forest Nutrients

Headwater streams--small tributaries in the outer reaches of a watershed--are the smallest parts of river networks. But collectively, they make up more than half the miles of flowing water in the U.S.  According to a new Harvard Forest study in the journal Ecosystems, headwater streams tell us volumes about the impacts of seasonal storms on forest ecosystems and water quality.
