Center For Forest Disturbance Science (SRS RWU 4156)

The Center for Forest Disturbance Science is a research project of the US Forest Service Southern Research Station focused on the study of disturbance processes across scales and their risk of occurrence in order to develop innovative management strategies for reducing vulnerability of ecosystems to degradation.

Spring Break Fire Training

Setting a forest on fire is not what you would call a typical a spring break activity. Sixteen graduate and undergraduate students from the University of Georgia (UGA) did just that during a course in wildland fire science at Savannah River Ecology Lab at the Savannah River Site in Georgia.

The course, Wildland Fire, is the first of its kind at UGA and was developed and taught by U.S. Forest Service SRS research ecologist Joe O’Brien and forester Ben Hornsby, along with UGA Warnell School of Forestry faculty Doug Aubrey.

Oaks, an Unrecognized Ally in Longleaf Pine Restoration

Longleaf pine ecosystems are among the most threatened in the U.S., and managers across the southeast are prioritizing longleaf restoration. The conventional approach calls for removing hardwood trees such as oak.

“Hardwood reduction techniques are commonly deemed necessary for ecological restoration of longleaf pine ecosystems,” says U.S. Forest Service research ecologist Louise Loudermilk. “Hardwoods are presumed competitors with longleaf pine seedlings.”

Grant to Clemson University Supports CAFMS Outreach

Although fires have roared through the Appalachian Mountains devouring thousands of acres since October, a Clemson University professor wants people to understand not all fires are bad.

Rob Baldwin, a forestry and environmental conservation professor, has received a three-year grant for $216,000 from the U.S. Forest Services to develop outreach activities for the Consortium of Appalachian Fire Managers and Scientists (CAFMS).

Into the Rhizosphere: Soil Fungi and Carbon Dynamics

Many tree species rely on mycorrhizal fungi to help them get water and nutrients. The relationship between trees and fungi also affects carbon dynamics in the soil. Photo by Melanie Taylor, U.S. Forest Service.

Underneath the Earth’s surface, water, nutrients, and chemical signals are shuttled through a sprawling network between tree roots and soil fungi. “Many forest trees depend on their associated soil fungi for nutrients, as the fungi are better at absorbing nitrogen, phosphorous, and other nutrients,” says U.S. Forest Service ecologist Melanie Taylor. “The trees return the favor by sharing their sugars with the fungi.”

Earthworms, Millipedes and Soil Carbon in the Eastern U.S.

Scientists look for earthworms, millipedes, and other soil macroinvertebrates in the thick layer of partially decomposed leaf litter at the soil surface. The photo was taken in the Bartlett Experimental Forest, New Hampshire, where no invasive earthworms were found. Photo by Evelyn Wenk, U.S. Forest Service.

Ubiquitous in the southeastern U.S., native earthworms are absent from the northern part of the country. It wasn’t always so, but tens of thousands of years ago glaciers crept across the land, and earthworms below them froze to death. Because earthworms are slow travelers, they have not naturally recolonized the areas where glaciers were present.

The Guide to Prescribed Fire in Southern Ecosystems

Prescribed burning is FIRE “applied in a skillful manner, under exacting weather conditions, in a definite place, to achieve specific results.”

Printed on the inside cover of the Introduction to Prescribed Fire in Southern Ecosystems, the sentence sets the tone for the revised guide developed by U.S. Forest Service Southern Research Station (SRS) scientists Tom Waldrop and Scott Goodrick and published by SRS in 2012.

Studying Woody Biomass for Energy Across the U.S.

Five U.S. Forest Service Southern Research Station (SRS) scientists – John Stanturf, Emile Gardiner, Leslie Groom, Dana Mitchell and James Perdue – recently contributed to four review articles that were part of a special issue of the journal BioEnergy Research. SRS researchers collaborated on the journal articles with scientists and engineers from a number of universities and other agencies, including the Forest Service Northern Research Station, Pacific Northwest Research Station, and Forest Products Laboratory, as well as the USDA Agricultural Research Service and Natural Resources Conservation Service.

The Future of Fire in the South

In the U.S., most of the focus is on the catastrophic fires that regularly sweep across the western states, but wildfires actually occur more frequently in the Southeast, where rapid vegetation growth and fuel accumulation combine with frequent ignitions from lightning and humans. The South leads the nation in annual occurrences of wildfire, averaging approximately 45,000 wildfires per year. Continued population growth in the South increases the potential threat that wildfires pose to life and property. In addition, forestry and forestry related-industry represent a significant portion of the region’s economy, making each wildfire a potential loss to a local economy.
