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 

Unexpected Pest of Chestnut Trees

SRS research entomologist Bud Mayfield was relieved to find that defoliation on an American chestnut planting site was not as severe as expected. Mayfield and SRS research forester Stacy Clark are coauthors on a paper in the Journal of Insect Science that describes a study they conducted with Ashley Case, an adjunct lecturer at the University…  More 

Women in Science: Stacy Clark

The new 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 Stacy Clark, a research forester with the Upland Hardwood Ecology and Management Research Unit in Knoxville, Tennessee. She received a B.S. from the University of Tennessee in Forest Management and…  More 

American Chestnut, Past and Present

The Silvics of American Chestnut , a general technical report (GTR) available from the U.S. Forest Service Southern Research Station (SRS), describes the habitat, life history, special uses, genetics, and restoration of the American chestnut (Castanea dentata). The publication is the result of collaboration between G. Geoff Wang, the lead author, his colleagues at Clemson…  More 

When American Chestnuts Return to the Wild

Until recently, most American chestnut studies took place in labs or in orchards, as scientists focused on developing a blight-resistant hybrid that would grow like pure American chestnut. “However, restoring chestnut requires field research to determine whether the hybrids can resist blight, root rot disease, and damage from insects and other diseases,” says U.S. Forest…  More 

Fulbright Grant Funds Three-Month U.S. Visit by Portuguese Researcher

To help keep the European chestnut from suffering the same plight as the American chestnut, Portuguese scientist and Fulbright grant recipient Rita Costa recently spent three months working at the U.S. Forest Service Southern Institute of Forest Genetics (SIFG) in Saucier, Mississippi, and the Forest Health Research and Education Center (FHC), Department of Forestry, at the University of Kentucky.…  More 

Where the Not-So-Mighty Chestnut Still Grows

A recent study by U.S. Forest Service, university, and state agency researchers provides baseline information on contemporary populations of American chestnut needed to support restoration of the tree to the forests it once dominated. Biologist Harmony Dalgleish from the College of William and Mary served as lead author on the research published in the journal…  More

Dreaming of Giants: The Future of American Chestnut Restoration

For almost a hundred years, foresters have dreamed of the American chestnut’s return. “As the 21st century unfolds, the chestnut restoration goal may be closer to reality,” says U.S. Forest Service Southern Reseearch Station (SRS) scientist Stacy Clark. “Chestnut restoration will require an integrated approach that uses traditional breeding, advanced seedling technology, and forest management,” says…  More 

Southern Institute of Forest Genetics Hosts International Student Visitor

Carmen Santos, a Ph.D. student from Lisbon, Portugal, recently traveled to Saucier, Mississippi, for an internship with the U.S. Forest Service Southern Research Station (SRS). Santos will be working with C. Dana Nelson, project leader and research geneticist at the SRS Southern Institute of Forest Genetics, and biological sciences lab technician Chuck Burdine. “We have…  More
