A broad-scale forest management issue needs a culture in which building long-term interactions and interdisciplinary teams is the norm. Sustaining upland oak forests under today’s disturbance regime is challenging. SRS researchers and partners continue to tweak a broad-scale, long-term applied silviculture study to find the best treatments to meet restoration goals.


A broad-scale study of applied silviculture to improve forest health and resiliency on the Daniel Boone National Forest in Kentucky continues to bring together researchers and managers to address restoration goals. Research forester Callie Schweitzer leads an interdisciplinary team that includes partners from the Northern Research Station, the University of Tennessee, and the University of Kentucky.

Amid changes in disturbance regimes and forest dynamics, the group is examining treatments to create conditions conducive to sustaining oak trees. Oak is highly valued for its economic and ecological attributes. In essence, small oak trees are being outcompeted by other tree species, and oaks are likely to lose their prominence in hardwood forests of the eastern U.S.

Managers and researchers recently amended the project plan, assessed the environmental impacts, and engaged with the public through field tours and social media. Researchers will examine the response of the forests as the silviculture prescriptions are applied; provide continuity for long-term monitoring; and add analyses related to restoration of the American chestnut, the impact of forest pathogens, and the consequences of prescribed fire. The project has created a culture in which building long-term interactions and interdisciplinary teams is the preferred model to approach forest management.
