Deadwood in Longleaf Pine Forests

Longleaf pine forests are important ecosystems for a broad array of wildlife and understory plant species, such as the red-cockaded woodpecker, the southeastern fox squirrel, and the venus fly trap. Over time, the forests have dwindled due to replacement by other land uses and the suppression of fires with which they evolved. Now, they are…  More 

Longleaf Pine on the Santee Experimental Forest

In 1989, South Carolina’s Francis Marion National Forest lost close to a third of its pine and hardwood trees to Hurricane Hugo. USDA Forest Service land managers have spent the last thirty years recovering from that disturbance and working to meet the state’s growing needs for clean water, forest products, recreation areas, and wildlife habitat.…  More 

Longing for Longleaf Pine

In the early 1800s, longleaf pine-dominated forests stretched from eastern Texas to southern Virginia and south into central Florida. These forests covered about 90 million acres — nearly the size of the state of Montana. The dense, tightly grained wood from these forests built some of America’s great cities and railroads. Vast sections were cleared…  More 

Carbon Storage in Longleaf Pine Roots

“Longleaf roots are pretty legendary,” says USDA Forest Service scientist Peter Anderson. “It’s common to hear that you can dig up a really old stump and use it as a quick, reliable kindling.” Pines contain oleoresins, a sticky liquid mix of oil and resin (or rosin). “There are companies today that buy and dig old…  More 

Louisiana’s First Lady of Forestry

Caroline C. “Carrie” Dormon was shaped by her family’s influence and interest in nature. Today she is recognized as a woman who excelled in a male dominated world – as well as a pioneer conservationist, forester, botanist, illustrator, and native plant enthusiast. USDA Forest Service emeritus scientist James Barnett, along with Sarah Troncale, science teacher…  More 

New Book on Restoring Longleaf Pine Ecosystems

A definitive book about longleaf pine ecosystem restoration is now available. Experts from the USDA Forest Service, Joseph W. Jones Ecological Research Center, and many other organizations contributed to the book. Ecological Restoration and Management of Longleaf Pine Forests integrates ecology, hydrology, wildlife, and silviculture. Its seventeen chapters synthesize decades of research on longleaf pine…  More 

Climate Influences Male-Female Balance in Longleaf Pines

For many reptile and fish species, temperature during egg incubation determines whether hatchlings are male or female. In the northern part of Australia’s Great Barrier Reef, scientists have discovered that 99 percent of immature green turtles hatched in warming sands are female, raising concerns about successful reproduction in the future. U.S. Forest Service scientists have…  More 

The Many Dimensions of Tree Trunks

The taller a tree grows, the wider its trunk becomes. “It’s a fundamental relationship,” says U.S. Forest Service research ecologist Dale Brockway. Scientists use math to describe this height-diameter relationship. But one of the mathematical constants – a scaling exponent of 2/3 – is not always so constant, according to a recent study by Brockway…  More 

Longleaf Pine Cone Prospects for 2017 and 2018

How many pine cones can managers expect from their longleaf pine forests? Every year, U.S. Forest Service research ecologist Dale Brockway attempts to answer this question. His most recent report suggests that 2017 will be a good year for longleaf pine cone production. “Across the region, we expect longleaf pines to produce an average of…  More 

Restoration in the Understory

Some plants are homebodies and refuse to thrive in new areas. “Plants have unique abilities to thrive where they grow but moving plants outside their genetically adapted environment might cause them not to grow as well,” says Joan Walker, SRS research plant ecologist. The U.S. Forest Service, led by Walker, is partnering with federal and state…  More
