Managing Oak-Pine Stands

About half of southern forests are a mix of oaks and pines growing side by side. In the past, getting rid of either the oaks or the pines had been a common management goal. “Pine plantations – stands with no oaks – have become one of the most recognizable symbols of forest management,” says John…  More 

Group Selection Harvest for White Oak Regeneration

Oaks are keystone species in forests across the eastern U.S. However, oak reproduction has been declining since at least the 1970s — old oaks still dominate the overstory, but a younger generation is not coming in behind. White oak, in particular, is valuable to wildlife and wood-dependent industries such as barrel, furniture, and cabinet making.…  More 

SRS Releases American Chestnut Course

The American chestnut (Castanea dentata) was an iconic tree that is now functionally extinct. For a hundred years, researchers from multiple organizations have been working to restore this tree. A free online course – An Introduction to the American Chestnut – is now available. The course covers chestnut taxonomy, silvics, historical importance, ecology, and its…  More 

The Quest to Sustain White Oak Under Fire

White oak (Quercus alba) is an incredibly important species, anchoring ecosystems and economies. Current demand for white oak is surging due to its use in making barrels to support a growing spirits industry. Thus, there’s a real need understand the best tools to promote and sustain white oak in forests to support both economic and…  More 

Remembering Glen Smalley

On August 2, 2020, Glendon W. Smalley died at his home in Sewanee, Tennessee. He was 92. Smalley was an Emeritus scientist with the Southern Research Station. 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 

The Southern Pine Module Goes Virtual

In 2019, Janet Hinchee, the USDA Forest Service Regional Silviculturist for the South invited me to coordinate the Southern Pine Module, a ten day workshop for the Forest Service National Advanced Silviculture Program. The workshop is a key element of the agency’s program for National Forest land managers, especially district silviculturists, to obtain required silvicultural…  More 

Past Partial-Cutting Techniques More Beneficial Than Past Clear-Cutting

What is the most sustainable way to harvest a forest? A team led by USDA Forest Service scientists Katherine Elliott and Chelcy Miniat, along with Forest Service intern Andrea Medenblik, tries to answer this question. Data were analyzed from a long-term study looking at the biomass effects of partial-cutting versus clear-cutting in different watersheds in…  More 

After Fire, Red Oak Seedlings Resprout

Disturbance – from fire and subsistence living to widespread exploitative logging – enabled the growth of oak (Quercus) forests across the eastern U.S. These disturbances are not common today. Reduced disturbance, coupled with a long-term increase in moisture availability has been good for non-oak trees, which establish and grow under the older oak canopy –…  More 

White Oak Regeneration in Canopy Gaps

In February 2020, USDA Forest Service scientist Stacy Clark planted 720 white oak (Quercus alba) seedlings on the Pisgah National Forest in western North Carolina. “White oak is declining in abundance across the eastern U.S., and we are concerned that wildlife species and industries around cooperages, distilleries, and flooring will be negatively affected without proactive…  More 

Genetics of Shortleaf and Longleaf Pine in Seed Orchards

Shortleaf pine (Pinus echinata) and longleaf pine (Pinus palustris) ecosystems have been dwindling for decades. Restoration is a huge priority for the USDA Forest Service, the Longleaf Pine Alliance, the Shortleaf Pine Initiative, and many others. Restoration requires seed, and on National Forest System lands the seed comes from USDA Forest Service seed orchards. The…  More
