Electrofishing for Crayfish

Since its origin, more than 40,000 years ago, fishing has taken a variety of forms — from spearing to hook-and-line fishing. In the 1960s, scientists began using a method called “electrofishing” to study aquatic populations. In a study published in the North American Journal of Fisheries Management, USDA Forest Service scientist Zanethia Barnett researched the…  More 

Santee Experimental Forest Research Forum

On April 1, 2021, scientists and experts from the South and across the globe gathered virtually to talk about research on the Santee Experimental Forest. Santee EF is one of 84 sites in the USDA Forest Service Experimental Forest & Range Network. It was founded in 1937, one year after the Francis Marion National Forest…  More 

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 

Freshwater Fishes of North America, Volume 2

The highly anticipated second volume of Freshwater Fishes of North America was just published by Johns Hopkins University Press. This volume was edited by USDA Forest Service fisheries research scientist Mel Warren and four other editors. Warren also contributed to seven of the book’s 35 chapters. “We are indebted to a large community of ichthyologists,…  More 

Carbon Pools and Fluxes in Southern Appalachian Forests

An estimated 35 percent of the global terrestrial carbon is stored in soil and biotic carbon pools, such as forests. These pools can store or release carbon. Because forests store immense amounts of carbon, forest management is becoming part of efforts to increase carbon sequestration and mitigate greenhouse gas emissions. Long-term research from the USDA…  More 

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 

Southern Forest Outlook: Synthesis of Regional Trends and Futures

The USDA Forest Service Southern Research Station and Southern Region, in partnership with the Southern Group of State Foresters, is leading an update to the Southern Forest Assessment Library, with a new regional assessment called the Southern Forest Outlook, or SFO. The SFO update will inform forest sector decision makers, partners, and the interested public…  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
