Climate Change, Streamflow, and Social Vulnerability: Locating Increased Risks

What happens when climate change or urbanization increases the frequency or severity of floods? How well can different downstream communities prepare for and respond to those catastrophic events? USDA Forest Service scientists and approached these questions in a new way. They developed a risk matrix that pairs the likelihood of high streamflow events – which…  More 

Darter Conservation

Increasingly, recovery plans for imperiled fish species include raising them in captivity and releasing them in the wild. Crystal Ruble of Conservation Fisheries, Inc, with SRS researchers Ken Sterling and Melvin Warren published a protocol for captive propagation of the Yazoo Darter (Etheostoma raneyi). The researchers also summarize its early life-history. Compared to other darter…  More 

Climate Change and the Future of Southern Wetlands

The Southeast hosts an impressive network of forested wetlands. These wetlands improve water quality, reduce flooding, store excess carbon, and provide important habitat for wildlife. They are also particularly vulnerable to changes in climate and land use. With researchers from North Carolina State University, USDA Forest Service scientist Peter Caldwell designed a model to assess…  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 

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 

Study Wins Water Resources Research Editor’s Choice Award

Over the last three decades, forest vegetation has begun using significantly more water, as long-term climate and streamflow data reveal. USDA Forest Service scientists Jim Vose and Dave Wear contributed to the study, which was led by Taehee Hwang, an assistant professor at the University of Indiana. The findings were published in the journal Water…  More 

Ying Ouyang Receives Soil Science Society of America’s Highest Honor

Research hydrologist Ying Ouyang was recently named a 2019 Fellow by the Soil Science Society of America (SSSA), the highest recognition bestowed by the organization. The SSSA is an international scientific society whose members are dedicated to advancing the field of soil science to sustain global soils. Each year, members nominate colleagues based on their professional…  More 

Future Increases in Biomass Demand Could Affect Wood Economy

Wood is used for an abundance of everyday items — furniture, buildings, paper — so much so that it would be difficult to find a space completely without wood-based products. However, a competing use is emerging: many studies predict that more wood will be used for bioenergy in the future, which could affect that industry…  More 

Where Does the Rain Go?

Millions of people depend on the forests of the Southern Appalachian Mountains for drinking water. As climate, land use, and land cover changes alter the forest structure in these mountains, they also alter water budgets. “The Southern Appalachian Mountains are a humid montane environment – they are essentially a cooler version of the tropics,” explains…  More 

Uncovering Urban Forests

The scope of forest-pest risk analysis research is often limited to natural forests. Neglected are those tree communities called urban forests: trees within the boundaries of a city or populated area. Urban trees see a significant proportion of the impacts from invasive pests. Their unnatural distribution and close proximity to transported goods and other means…  More
