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 

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 

Highlighting Heirs’ Property Ownership and Land Loss

A USDA Forest Service publication on heirs’ property ownership across the southern U.S. highlights a kind of land ownership prevalent among lower wealth, African Americans in the Black Belt South, central Appalachian whites, and Hispanic Americans in U.S. southwest colonia communities. A meeting co-hosted by the Southern Research Station and the Federal Reserve Bank of…  More
