Forest Birds & Forest Trees

For every stage of forest succession, there’s a bird species that needs it. But others are flexible, thriving in many types of forests. The blue-gray gnatcatcher, eastern wood-pewee, great crested flycatcher, summer tanager, and white-breasted nuthatch are all associated with mature forests. But a recent study suggests these birds are forest generalists rather than mature…  More 

Definitive New Book on Saproxylic Insects

Bark-feeders, fungus-feeders, wood-borers, and wood-nesting bees – all are saproxylic insects, which means they depend on dead or dying wood. The insects that prey on or parasitize them are also considered saproxylic. “About a third of all forest insect species are saproxylic,” says USDA Forest Service research entomologist Michael Ulyshen. Ulyshen recently edited a definitive…  More 

The Climate Is Changing—What’s a Silviculturist To Do?

Climate change is here. In southern forests, it takes the form of novel disturbances – different frequency and severity of drought, fire, wind storms, insect outbreaks, even ice storms – or a combination of these stressors. “How will managers respond to the threats posed by changing climate conditions?” asks USDA Forest Service scientist James Guldin.…  More 

Arkansas Research Forester Receives International and Regional Honors

Silvicultural histories are recognized by forestry professionals from the United Kingdom to Arkansas. The Editorial Board of Forestry, an international journal of forest research, recently awarded USDA Forest Service research forester Don Bragg the 2017 Percy Stubbs, John Bolton King and Edward Garfitt Prize for Silviculture for advancing silviculture research. Bragg received this prestigious award…  More 

Women in Science: Callie Schweitzer

The Women in Science series features women scientists from across the Southern Research Station (SRS)–their education, career paths, challenges, achievements, and inspirations. Meet SRS scientist Callie Schweitzer, a research forester with the Upland Hardwood Ecology and Management Research Unit in Huntsville, Alabama. She received her doctorate and master’s degrees in Forest Resources and Ecology from Pennsylvania State University.…  More 

National Silviculture Workshop

In 1973, foresters and scientists gathered for the first U.S. Forest Service National Silviculture Workshop. Since 1979, the workshop has been held every two years. The workshop brings two branches of the U.S. Forest Service – the National Forest System and Research & Development – together to address silvicultural challenges. University scientists and managers from…  More 

Introducing Femelschlag

Visitors to the Cradle of Forestry (located near Brevard in Pisgah National Forest) learn about the Biltmore Forest School – the first school of forestry in North America. It was started in 1898 by Carl Schenck. A native of Germany, Schenck brought German forestry concepts to the United States. It is fitting that today in…  More 

American Chestnuts in the Field

By the 1950s, two non-native pathogens had killed almost all American chestnut trees. “There’s a lot of interest in breeding a chestnut that looks like American chestnut with the disease resistance of Chinese chestnut,” says U.S. Forest Service research forester Stacy Clark. “However, there hasn’t been much research on reintroducing disease-resistant trees to the forest.”…  More 

Where Are the Southern Pine Beetles?

Between 2005 and 2015, only 18 counties in the southern U.S. experienced southern pine beetle outbreaks–fewer than two outbreak counties per year on average. U.S. Forest Service entomologist Chris Asaro wanted to know why and worked with two other Forest Health Protection scientists, John Nowak and Anthony Elledge, on a new review paper published in Forest…  More 

Longleaf Pine Silviculture

By best estimate, longleaf pine forests once spanned over 90 million acres – an area more than twice the size of Georgia. “Today, 97 percent of these forests are gone,” says U.S. Forest Service research ecologist Dale Brockway. “However, the longleaf pine ecosystems that remain are home to a very diverse community of plants and…  More
