Seed Size & Predation

Among their many benefits, prescribed fires can protect southeastern pine woodlands from encroachment – the process of fire-sensitive species expanding into fire-maintained woodlands. Because fire is important for longleaf pine regeneration, forest researchers have studied the effects of flammability on the pine woodlands. In a recent study published in in Applied Vegetation Science, USDA Forest…  More 

History of Forest Research in the South, 1921-1933

For 40 years, Philip Wakeley researched southern pines for the USDA Forest Service. Wakeley was one of the first Forest Service R&D employees in the South. He began his career in 1924, at the Southern Forest Experiment Station in New Orleans, Louisiana. The Station was established in 1921, and in the 1990s would merge with…  More 

A History of Naval Stores, a Forgotten Forest Industry

Before the advent of modern boats, wooden ships made up the navies of our world. Naval stores – pitch, tar, turpentine, and rosin – were used to caulk seams, preserve ropes, and maintain the seaworthiness of wooden ships. Naval stores also found many other uses prior to the modern petrochemical era. USDA Forest Service emeritus…  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 

Top Ten of 2020

As 2020 comes to an end, it is a good time to gather our most-read CompassLive stories from the past year. Each one highlights the work of USDA Forest Service scientists at the Southern Research Station. We hope you enjoy reading this collection, which includes the most popular of 2020 plus a few more that…  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 

Hardwood-Cypress Swamps, Unlikely Fire Hazards

In parts of the southeastern U.S., one unlikely forest type has great potential for extreme fire behavior: hardwood-cypress swamps. These shallow wetlands can work with their more frequently burned neighbors, pine flatwoods, to wreak havoc by easily igniting and sustaining tremendous wildfires, thus depleting carbon storage in these forests. Hardwood-cypress swamps and pine flatwoods are…  More 

Bees of Longleaf Pine Forests

Old-growth, or primary forests, are classified as having very little human disturbance — and thus they provide a unique opportunity to study life in relatively unchanged settings. Previous research suggests that these ecosystems may provide critical habitat for sensitive species that are absent or rare in other places. However, past studies comparing bee biodiversity in…  More 

Timing Prescribed Fire to Maximize Longleaf Pine Growth

Longleaf pine (Pinus palustris) needs fire to thrive. But if seedlings burn too late in the growing season, they may not have enough energy to re-grow their scorched leaves and replenish their starch reserves before spring of the next year. “When seedlings are so short that a prescribed fire is likely to scorch all of…  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
