UT Tree Improvement Program highlights seed orchards and TWRA partnership for large‑scale restoration
Summary
Dr. Scott Schlarbaum briefed commissioners on UT’s 67‑year tree improvement work: genetically improved and locally adapted seed production, seed orchards across Tennessee, conservation of rare species and an MOU with TWRA that supported about 10,000 acres of bottomland hardwood restoration.
Dr. Scott Schlarbaum told the commission the University of Tennessee Tree Improvement Program develops genetically improved and locally adapted seed and seedlings for restoration, wildlife habitat and timber. The program operates seed orchards and a wild forest seed collection network and works under MOUs with the Tennessee Wildlife Resources Agency and the Tennessee Division of Forestry.
Schlarbaum explained the program’s dual selections for timber qualities and wildlife value, noted the program covers 44 species (including persimmon and serviceberry important to wildlife) and described success in transferring seed‑production technology to agencies; he cited roughly 10,000 acres restored in West Tennessee using local seed sources. He said the program’s longevity and species diversity make it unique and emphasized operational needs: once orchards mature the program must scale capacity for seed collection and orchard management.
Commissioners thanked Schlarbaum and asked about succession planning; he warned that the retirement of applied forest geneticists nationwide threatens similar programs and urged organizational adjustments to preserve applied capacity. He also described work conserving rare species such as sand cherry through grafting and establishment of seed orchards.
