Hardwood-Cypress Swamps, Unlikely Fire Hazards

In parts of the southeastern U.S., one unlikely forest type has great potential for extreme fire behavior: hardwood-cypress swamps. These shallow wetlands can work with their more frequently burned neighbors, pine flatwoods, to wreak havoc by easily igniting and sustaining tremendous wildfires, thus depleting carbon storage in these forests. Hardwood-cypress swamps and pine flatwoods are…  More 

FIA Data Inform Studies on Land Use Conversions, Markets, and More

Strong forest markets protect forests by reducing conversion of forests to other land uses, according to a recent study. The study uses data from the Forest Inventory and Analysis program. “Across the Southeast and the rest of the U.S., FIA provides detailed observations of every aspect of the forest resource,” says John Coulston, a USDA…  More 

SRS Contributes to Fourth National Climate Assessment

Long hours, lots of reading, and collaborating with fellow scientists around the world is some of what goes into overseeing a chapter for the Fourth National Climate Assessment (NCA4). SRS senior research ecologist James Vose was a federal coordinating lead author and chapter lead for Chapter 6 – Forests of the NCA4. SRS senior economist…  More 

Mangroves of Mozambique

Whether small and shrubby or tall and majestic, mangroves have an unusual ability – they are specially adapted to grow in brackish water, and can tolerate ocean waves lapping at their stilt-like roots. As stands mature, soil and decaying plant matter becomes captured in the intricate web of their roots. “The soil in mangrove ecosystems…  More 

Where’s the Carbon?

Carbon is the foundational element of life, and trees use atmospheric carbon dioxide to grow. “Trees can partially offset carbon dioxide emissions,” says U.S. Forest Service plant physiologist John Butnor. “Trees pull carbon out of the atmosphere and store it for long periods of time.” Butnor and his colleagues studied carbon storage in longleaf pine…  More
