Hemlock Woolly Adelgids & Their Predator Beetle, Laricobius nigrinus

Laricobius nigrinus is a small beetle that eats an even smaller bug – the hemlock woolly adelgid, or HWA. Since 2003, Laricobius has been used to help control HWA. But the beetle, which is native to western North America, is only active during the fall, winter and early spring. Recently, USDA Forest Service research entomologist…  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 

When Birds Attack Snakes

It’s a bird! It’s a plane! No, it’s … birds attacking a Jamaican boa? In a recent study by USDA Forest Service scientists Richard Schaefer and Craig Rudolph (retired), along with colleagues from Jamaica and Washington, DC, the previously undocumented mobbing of Jamaican boas is brought to scientific light. The act of multiple birds screeching…  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 

Hill Demonstration Forest Joins Experimental Forest Network

The USDA Forest Service Southern Research Station and the North Carolina State University College of Natural Resources recently signed an agreement adding NC State’s Hill Demonstration Forest to the SRS Experimental Forest Network. The Hill Demonstration Forest covers more than 2,600 acres in the Carolina Slate Belt and has a variety of forest types and…  More 

Remembering Glen Smalley

Smalley began working for the USDA Forest Service in 1953 on the Sam Houston National Forest in Texas, where he met his wife Mary, who passed in 2017.…  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 

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 

Upland Hardwood Silvicultural Workshop Goes Virtual

In July, state forest agencies, National Forest System managers, and others convened digitally for the Upland Hardwood Silvicultural Workshop. The virtual workshop, organized by the USDA Forest Service Upland Hardwood Ecology and Management Research Work Unit, consisted of half-day sessions in which natural resource practitioners learned the most up-to-date hardwood forest management practices based on…  More
