Years After Apollo 14, Moon Pines Continue to Travel Around the World

Apollo 14 landed on the moon in 1971, the third manned mission to land on Earth’s only natural satellite. The spacecraft carried an unusual cargo – tree seeds. Astronaut Stuart Roosa — previously a smoke jumper for the U.S. Forest Service — carried several hundred seeds from loblolly pine and four other tree species with him on the…  More 

The Coweeta Hydrologic Laboratory

Much of what we know today about the hydrology of forested watersheds was learned through early research at the U.S. Forest Service Coweeta Hydrologic Laboratory (Coweeta). Established in 1933 as the Coweeta Experimental Forest, the laboratory represents the longest continuous environmental study on any landscape in North America, as well as one of the oldest…  More 

SEEDS for the Future

During April 13-16, 2016, scientists and staff at the U.S. Forest Service Coweeta Hydrologic Laboratory hosted the Strategies for Ecological Education and Diversity (SEEDS) 11th annual leadership meeting. An award-winning program of the Ecological Society of America (ESA), SEEDS focuses on students at the undergraduate level, with the mission to diversify and advance the ecology profession…  More 

Open or Shut: How Trees Respond to Drought at the Leaf Level

Trees pull water into their roots, where some of it moves up the trunk against the pull of gravity. This upward movement, which is described by the cohesion-tension theory, is possible because of the chemical nature of water. Water molecules are attracted to each other (cohesion), so just before a water molecule evaporates from the…  More 

Fires, Fuels, and Longleaf Pine in the Western Gulf Region

On April 6, 2016, scientists from the U.S. Forest Service Southern Research Station (SRS) presented findings on prescribed fire, longleaf pine, and other topics during an all-day workshop titled “Louisiana Fire, Fuels, and Longleaf Pine Management: Lessons from the Kisatchie National Forest and the Palustris Experimental Forest.” Mary Anne S. Sayer, SRS research plant physiologist…  More 

The Complexities of Longleaf Pine Cone Production

“Longleaf pine forests are among the most important ecosystems in the southeastern United States,” says U.S. Forest Service research ecologist Qinfeng Guo. “However, they have declined dramatically since European settlement and are considered endangered.” Longleaf pine ecosystems once covered an estimated 80 to 90 million acres across the southeastern U.S. – from Virginia to Texas – but…  More 

The Santee Experimental Forest

In 1934, the U.S. Forest Service allocated 6,100 acres (2,470 ha) of the Francis Marion National Forest (Francis Marion) near Charleston, South Carolina, for the Santee Experimental Forest (the Santee). By the 1930s, much of the site had been heavily used for centuries, the upland cleared to raise livestock and produce naval stores (tar, pitch, turpentine, and…  More 

Santee Experimental Forest Chosen for U.S.-China Climate Change and Forests Initiative

U.S. Forest Service Southern Research Station scientists and the Santee Experimental Forest (Santee) located in the Francis Marion National Forest near Charleston, South Carolina, have been chosen to participate in the U.S,-China Climate Change and Forests Initiative, a new program  of the U.S.-China Climate Change Working Group sponsored by the U.S. Department of State. The U.S.-China…  More 

The Calhoun Experimental Forest

Until the middle of the 20th century, forest researchers were mostly concerned with what could be done above the ground — growing trees, protecting them from insects and diseases, maximizing productivity, and regenerating stands after harvesting. It was not until 1947, when the Calhoun Experimental Forest (Calhoun) was established on the Sumter National Forest in…  More 

U.S. Forest Service’s First Woman Research Forester

Margaret Stoughton Abell Margaret Stoughton graduated from Iowa State College, Ames, Iowa, in 1930 with a bachelor’s degree in forestry. In June 1930, she joined the staff of the Appalachian Forest Experiment Station in Asheville, North Carolina, becoming the first woman forester in the Forest Service. Her name changed when she married Charles A. Abell, also…  More
