Upland Hardwood Silvicultural Workshop Goes Virtual

In July, state forest agencies, National Forest System managers, and others convened digitally for the Upland Hardwood Silvicultural Workshop. The virtual workshop, organized by the USDA Forest Service Upland Hardwood Ecology and Management Research Work Unit, consisted of half-day sessions in which natural resource practitioners learned the most up-to-date hardwood forest management practices based on…  More 

The Southern Pine Module Goes Virtual

In 2019, Janet Hinchee, the USDA Forest Service Regional Silviculturist for the South invited me to coordinate the Southern Pine Module, a ten day workshop for the Forest Service National Advanced Silviculture Program. The workshop is a key element of the agency’s program for National Forest land managers, especially district silviculturists, to obtain required silvicultural…  More 

Water Supply from Southern State and Private Forest Lands

Forests provide the most stable and highest quality water supplies among all land uses. A report by the Southern Research Station of the USDA Forest Service quantifies the role of state and private forest lands (SPF) in providing drinking water supply across the southern United States. About half of the South’s land area is forested,…  More 

Assessing Surface Water Quality in the Mississippi Delta

USDA Forest Service scientists are measuring surface water quality in the Big Sunflower River watershed of the Mississippi Delta to better understand eutrophication of the Gulf of Mexico. Extensive crop production contributes nutrients and suspended solids and leads to concerns about low dissolved oxygen and pathogens. Ying Ouyang, Ted Leininger, and colleagues monitored water quality…  More 

Wood-Boring Beetles Not the Primary Cause of Sugarberry Mortality

In the past decade, sugarberry trees (Celtis laevigata) have been rapidly declining throughout South Carolina and Georgia. Alongside University of Georgia researcher Emilee Poole, USDA Forest Service scientists Scott Horn, Michael Ulyshen, and others studied the distribution and biology of the wood-boring beetle Agrilus macer to determine its role in recent sugarberry mortality. Using sugarberry…  More 

Impact of Fire Management on Breeding Birds in the Southern Appalachians

To increase the prescribed “burn window” for reaching restoration goals, land managers are now burning during winter (the dormant season) as well as spring and summer (the growing season) and fall. Management goals often include fuel reduction, oak regeneration, habitat improvement for target wildlife species, and forest restoration to conditions once created by Native Americans…  More 

Student to Teacher

In Nacogdoches, Texas, a USDA Forest Service office is located on the campus of Stephen F. Austin State University (SFA). When not in the field, it’s where research wildlife biologist Dan Saenz works. Saenz works closely with SFA professors. As a guest lecturer in 2007, he met Erin Childress, who was an undergraduate student at…  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 

E-Noses Detect Emerald Ash Borer Larvae

Electronic noses are sensitive to a vast suite of volatile organic compounds that every living organism emits. A new USDA Forest Service study shows that e-noses can detect emerald ash borer (Agrilus planipennis) larvae lurking under the bark – an early, noninvasive detection method. “The results were quite spectacular,” says Dan Wilson, a research plant…  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
