Dead Wood, Insects, and Fire

Dead wood is a secret harbor of biodiversity. About one-third of all insect species are saproxylic – or dependent upon dead wood – at some stage in their life cycle. The effects of common forest management practices on this important resource and the insects that use it are understudied, especially in subtropical climates. USDA Forest…  More 

Research Partnerships with Native American Communities

“The Southern Research Station is working with a number of Native American tribes to promote forest ecosystem restoration and sustainability,” says Monica Schwalbach, USDA Forest Service assistant director. The projects focus on sustainability of botanical species that are important to indigenous communities. SRS researcher Michelle Baumflek is the science lead for many of these projects,…  More 

A Yearly Health Checkup for U.S. Forests

Every year, the USDA Forest Service Forest Health Monitoring (FHM) program tracks changing forest conditions, including national assessments as well as focused regional analysis. The resulting report is the only national summary of forest health undertaken on an annual basis. Forests constantly change as a result of tree growth and mortality, weather events and climate…  More 

New Directions for Fire Ecology Research

Fire is a complicated process that affects forests in diverse ways. Current methods for predicting fire effects on forests still largely rely on past observations rather than a deep understanding of how fire interacts with a forest environment. In order to more fully understand fire’s effect on an ecosystem, wildland fire must be viewed as…  More 

Trees Survive Windstorms in Upland Hardwood Forest

In 1995, Hurricane Opal toppled trees throughout the South, including parts of the southern Appalachians. Wind is a common canopy disturbance in upland oak-hickory forests, but little has been reported on naturally formed large gaps of more than six trees where a partial canopy remains. With Erik Berg, SRS researchers Stanley Zarnoch and Henry McNab…  More 

Dams & Crayfish Genetics

In Alabama, crayfishes are being separated and genetically changed, which increases the risk of local extinction. This work is not done by a mad scientist, but by dams with their reservoirs and unnatural pools of water. A novel study published in the journal Freshwater Biology by USDA Forest Service scientists Zanethia Barnett and Susan Adams,…  More 

Temperature Drives Invasive Asian Earthworm’s Hatching Success

Amynthas agrestis is an Asian earthworm that has become increasingly abundant in North American forests. The earthworms consume massive quantities of leaf litter, disrupt established food webs, and outcompete native species. Ideas for control have been limited by the lack of information on their life history traits, such as optimal hatching temperature. With UGA graduate…  More 

After Fire, Red Oak Seedlings Resprout

Disturbance – from fire and subsistence living to widespread exploitative logging – enabled the growth of oak (Quercus) forests across the eastern U.S. These disturbances are not common today. Reduced disturbance, coupled with a long-term increase in moisture availability has been good for non-oak trees, which establish and grow under the older oak canopy –…  More 

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 

Insights from the 2016 Southern Appalachian Wildfires

Depending on their timing and location, fires can destroy or restore, with little gray area in between. In the early fall of 2016, one specific fire event in Southern Appalachia was unlike any other in recent decades, leaving behind unprecedented devastation once the fire had ceased. From this disastrous fire season comes a recent report…  More
