Acorns and Their Predators

Acorns aren’t only for squirrels. They serve as a food source for a variety of wildlife, such as mice, deer, and turkeys. This presents somewhat of a problem for oak trees – acorn producers – because their future depends on acorns surviving and germinating to become the next generation. A recent study by USDA Forest…  More 

Species Selection for Woody Biomass Production

In the southeastern U.S., short-rotation woody crops are a significant part of a growing renewable energy supply. A USDA Forest Service study examines how growing different tree species for bioenergy may have impacts on water yield. “Loblolly pine has long been considered the go-to woody bioenergy species in the South,” says Peter Caldwell, research hydrologist…  More 

Women in Science: Katie Greenberg

The Women in Science series features women scientists from across SRS – their education, career paths, challenges, achievements, and inspirations. Meet Cathryn (Katie) H. Greenberg, a research ecologist with the Upland Hardwood Ecology and Management unit located at the Bent Creek Experimental Forest in Asheville, North Carolina. Her research focuses on how disturbances, both natural…  More 

Barriers to Bioenergy?

At the national level, bioenergy is seen as a crucial component of a secure and renewable energy plan. Many people view southern forests as prime resources to support the hopeful bioenergy industry. But how is the national agenda for bioenergy received by communities in the South? “We are interested in understanding how the national discourse…  More 

Amphibian Life Cycles and Climate Change

From the trees in the forest to the various organisms populating it, all species of plants and animals have periodic life cycle events. Changes in climate have impacted the timing of these life cycle events for many species. This, in turn, can affect how likely coexisting populations are to interact with each other. A study…  More 

Effects of Forest Fragmentation and Restoration on Invasive Species

Managing invasive species is one of the largest challenges that land managers face. They threaten the health of natural ecosystems, prevent the growth of native species, and leave landowners with significant amounts of damage. “More than 4,300 exotic plant species and 66 foreign pest species that can cause negative effects on forest ecosystems and economies…  More 

Call for Abstracts: the 2019 FIA Stakeholders Science Meeting

The USDA Forest Service Forest Inventory and Analysis Program (FIA) and NCASI are pleased to announce that registration is now open for the 2019 FIA Stakeholders Science Meeting to be held November 19-21, 2019 in Knoxville, Tennessee. The meeting will bring together international forest scientists, managers, and stakeholders to share insights on contemporary issues, science…  More 

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 

Projecting Climate Change Effects on Outdoor Recreation

Cool temperatures enjoyed by hikers might rise enough that people decide to stay inside instead. The culprit – climate change – will cause higher temperatures and uneven intensification of both drought and rainfall. As a result, outdoor recreation trends could change markedly. A study by University of Georgia postdoctoral research associate Ashley Askew and USDA…  More 

Bachman’s Warbler

From 1975 to 1979, Paul Hamel and colleagues spent 7,000 hours walking through the Francis Marion National Forest and adjacent lands in South Carolina, playing the song of the Bachman’s Warbler and listening for the response that never came. “Eventually, my adviser said ‘this is a biology department, not a history department!’ So I expanded…  More
