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 

Two New Species of Crayfish Discovered in Alabama and Mississippi

In 2011, a group of researchers traveled to southern Alabama and Mississippi in search of the Rusty Gravedigger crayfish (Lacunicambarus miltus). They wanted to refine the species’ range and hoped to find a new population west of Mobile Bay. Instead, they found a potentially undescribed species of crayfish. Years later, a team led by Mael…  More 

Digging Deep for Crayfish Clues

Kneeling in a wet prairie, arm extended to the armpit in a muddy hole, most biologists would quickly arrive at the thought, “There’s got to be a better way.” So it’s not surprising that, when it comes to sampling for burrowing crayfishes, researchers have devised some creative solutions. In the southeastern U.S. – the global…  More 

Pondberry Responds to Light Availability and Soil Flooding

Pondberry is endangered, but it can persist through environmental stress. It prefers partial sun but can linger in deep shade for years. It can survive long periods of soil flooding, and even flowers while it’s flooded. “All indications are that this species would benefit from active management,” says Emile Gardiner, a USDA Forest Service research…  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 

Research for Mississippi and Beyond

Water defines the Mississippi Delta, an alluvial plain in northwest Mississippi. The Delta is sandwiched between the Yazoo and Mississippi Rivers, and a network of levees and pumps aim to keep the land dry enough for habitation and agriculture. In 2019, however, historic flooding left fields inundated for months. USDA Forest Service scientists have served…  More 

Using CAT in Local Watersheds

General circulation models use math to predict the future – future rainfall and temperature data, for example. But GCMs are meant for global or regional scales. “CAT is better for fine scales,” says USDA Forest Service research hydrologist Ying Ouyang. CAT, the Climate Assessment Tool, is a model developed by the U.S. Environmental Protection Agency.…  More 

Women In Science: Zanethia Barnett

The Women in Science series features women scientists from across the Southern Research Station (SRS) – their education, career paths, challenges, achievements, and inspirations. Meet Zanethia Barnett, a natural resource specialist from the Center for Bottomland Hardwoods Research in Oxford, Mississippi. Specializing in freshwater fauna and aquatic ecosystems, Barnett conducts her research in the lakes, streams,…  More 

Coastal Plain Fish Diversity and Introduced Small Wood

Coastal plain streams don’t always have swirling eddies or meandering bends. “They can look more like drainage ditches than natural streams,” says USDA Forest Service technician Ken Sterling. Agriculture, flood abatement, and residential development have all contributed to stream straightening in this region. The result? Streams incise and downcut, like a canyon. “These streams are…  More 

Post-Fire Mortality for Southern Hardwoods

Drive down Highway 7 in northern Arkansas, winding through the Ozark National Forest, and you may glimpse evidence of recent fire: scorched grass, darkened tree bark, maybe even a lingering wisp of smoke. Traces of prescribed burning can be seen throughout the South. Prescribed fire is a critical tool for forest restoration. A new study…  More
