Impacts of Urbanization on U.S. Watersheds

Urbanization is inevitable with a growing population, but what consequences does this have for the water we rely on? Cheng Li, a former visiting scholar at North Carolina State University from the Guangdong Academy of Sciences, along with USDA Forest Service scientists Ge Sun, Peter Caldwell, and Erika Mack modeled the effects of urbanization on…  More 

QUIC-Fire: A Fast Tool for Prescribed Fire Planning

Predicting fire behavior is complicated. Current modeling tools work to balance the interplay between many different factors including weather conditions and vegetation structure. Yet these tools are often underutilized because they require high-performance computing resources. Rodman Linn from the Los Alamos National Laboratory, with expertise from SRS researchers Scott Goodrick and Joe O’Brien and additional…  More 

Photo Guide to Fuel Loads in the Southern Appalachians

A new photo guide shows fuel loads in the Southern Appalachian mountains. A team of four experts wrote the guide: Adam Coates, a professor at Virginia Tech; Tom Waldrop, a USDA Forest Service research forester who is now retired; Todd Hutchinson, a research ecologist at the Northern Research Station; and Helen Mohr, an SRS forester…  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 

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 

Satellite Mapping of Forest Disturbances Can Help When Field Efforts Are Restricted

A large number of tornadoes struck the Southeast in the spring of 2020. Ordinarily, aerial surveillance and field crews would assess forest damage after windstorms and other disturbances, but the COVID-19 pandemic has limited those operations. USDA Forest Service scientists are showing that, with recent technological advances, disturbance impacts can nonetheless be rapidly mapped at…  More 

New Zones Delineate Seed Source Regions

Plant seeds are the crucial starting point for innumerable conservation projects, from backyard butterfly gardens to large reforestation projects. For the USDA Forest Service and its many partners, tree, shrub, and herbaceous plants’ seeds and seedlings are needed in large numbers for forest restoration and land management work. “In any such effort, it is important…  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
