One of the goals behind a recent partnership among UTIA and state agencies is the promotion of heartier food species such as this oak. The new five-year agreement between the UTIA Tree Improvement Program, the Tennessee Division of Forestry and the Tennessee Wildlife Resources Agency focuses on developing locally adapted and genetically improved seed for future Tennessee forests.

KNOXVILLE — A new, five-year agreement establishes how the state of Tennessee and a program in the University of Tennessee Institute of Agriculture will study and produce tree seedlings to promote the protection and conservation of Tennessee forests.

The UTIA Tree Improvement Program (UT-TIP), the Tennessee Department of Agriculture Division of Forestry (TDF) and the Tennessee Wildlife Resources Agency (TWRA) partnered on the agreement.

“Honoring our land-grant mission, we are excited about this partnership to responsibly research, develop, manage and conserve forest resources across the great state of Tennessee,” said Keith Carver, UTIA senior vice chancellor and senior vice president.

UT-TIP manages numerous seed orchards in East, Middle and West Tennessee with help from state and federal partners. It uses the orchards to provide the East Tennessee Nursery with locally adapted and genetically improved seed. 

This white oak (Quercus alba) in Burlington, N.J. is known as the Keeler Oak. It is an estimated 300 years old and is emblematic of the role these massive trees can play in the forest and beyond. The white oak is a highly valuable tree, both economically and ecologically. Its seedling survival rate is declining, but University of Tennessee researchers joined others to map the species’ DNA.  Wikipedia Commons

New research involving University of Tennessee describes the genome of the mighty white oak

KNOXVILLE — Highly valued economically, ecologically and culturally, the white oak (Quercus alba) is a keystone forest species and is one of the most abundant trees across much of eastern North America. It also faces declining seedling recruitment in many parts of its range.

In a paper published in New Phytologist, researchers representing the University of Tennessee Institute of Agriculture, Indiana University, the University of Kentucky, the U.S. Forest Service and several more institutions described for the first time the species’ complex genome, providing insights into fundamental questions about plant evolution, tree breeding and genetic improvement efforts that could help forest managers plan for and address future forest resources.

Lead authors of the paper Meg Staton, associate professor of bioinformatics and computational genomics in the UT Department of Entomology and Plant Pathology, and Drew Larson, National Science Foundation postdoctoral fellow at Indiana University, coordinated with colleagues across the nation in academia, the U.S. Forest Service, state forests and industry to obtain genetic sequence data representative of the species.

Also central to the effort were Seth DeBolt, professor of horticulture and director of the James B. Beam Institute for Kentucky Spirits at the University of Kentucky, and Dana Nelson of the U.S. Forest Service Southern Research Station and director of the Forest Health Research and Education Center at the University of Kentucky.

White oak barrels are lifeblood to the bourbon industry because the color and much of the whiskey’s flavor derive from the charred wood in which it is aged.

KNOXVILLE — The National Champion Tree Program (NCTP) will take nominations for new Champion Trees on its website starting Feb. 28. The list of eligible tree species for the 2025-2026 register includes more than 1,200 species of trees native and naturalized to the U.S., a steep increase from the 900 species eligible for the 2024 register. It is available online in the Register of Champion Trees. Nominations for potential Champions will stay open through August 2025.

“Each year, people find ‘new’ Champions all over the country,” said Jaq Payne, NCTP director. “It could be the tree in your backyard, the tree in front of your church or the tree in one of your local parks or state forests.” For the first time in the program’s 84-year history, an additional list of “culturally important non-native” eligible species will be included to represent common, widely recognized urban species previously not found on the register.

Champion Trees are identified based on a point system including the trunk circumference, height and average crown spread. After members of the public nominate trees, the NCTP will work with state coordinators to verify the submissions and their measurements. Verified trees will be added to the program’s data management system. National Champion Trees are crowned once every two years and must be re-verified every 10 years.
