How Drought and Thinning Affect Water Balances in Southeastern Pine Plantations

Evapotranspiration – the combination of water evaporation and plant transpiration – is an essential process for forests and water supply and climate. This is particularly true in the Southeastern U.S. where evapotranspiration from forested watersheds can return 50 to 90 percent of annual precipitation to the atmosphere. Until now, there has been a gap in…  More 

Rediscovering the Yalobusha Rivulet Crayfish

In 1989, Joseph Fitzpatrick discovered the Yalobusha rivulet crayfish (Hobbseus yalobushensis). After the species description was published, silence reigned. For the next 29 years, no studies focused on the species. “That’s not uncommon,” says USDA Forest Service aquatic ecologist Susan Adams. “We know very little about the ecology and life history of many crayfish species.”…  More 

Termites and Dead Wood in Pine Plantations

A handful of the world’s 3,100 known termite species damage homes. In forests, however, termites are valuable. “Termites recycle dead wood,” says U.S. Forest Service research entomologist Michael Ulyshen. Termites consume as much as 20 percent of the dead wood in forests, as Ulyshen showed in 2014. “Dead wood exists at the interface between below…  More 

Coweeta Receives Grant to Study Hydrology of Bioenergy Crops

U.S. Forest Service Southern Research Station (SRS) Coweeta Hydrologic Laboratory (Coweeta) scientists and collaborators recently received a $972,000 grant from the USDA Agriculture and Food Research Initiative (AFRI) to study water use in loblolly pine—the most commercially important tree species in the southeastern U.S. and the primary candidate for woody bioenergy production in the region—and…  More 

Carbon In, Carbon Out

Look around at all the wood and paper products we consider essential for daily life. Now, consider the carbon stored in those products—carbon that was removed from a forest ecosystem when trees were harvested. This type of carbon storage is quite important: while it’s locked into these products throughout their useful life, this carbon is…  More
