Bourbon Barrels and Bottlenecks: a Nuanced Look at Thirty Years of White Oak Population Dynamics

White oak (Quercus alba L.) is an ecologically and economically important tree species, common in upland hardwood forests throughout the eastern United States (US). This study examines the population dynamics of this foundational species over the past 30 years, highlighting both range-wide and regional metrics of change. Using data from the USDA Forest Service Forest Inventory and Analysis program, we analyzed changes in age and size distributions, as well as recruitment, mortality, and growth rates. We found a significant shift towards an older, mature-dominant population, with a notable decline in young age classes. Despite substantial increases in standing volume, net annual recruitment for trees with a diameter at breast height (dbh) ≥ 5 in. was negative—a concerning result for long-term sustainability if persistent. Regional analyses highlighted variation as most areas showed no signs of overutilization, but some exhibited volume reductions over the last 30 years and currently unsustainable growth-to-drain ratios. Other areas, spanning almost ¾ of the study region exhibited either seedling or sapling scarcity suggesting recruitment- or establishment-based bottlenecks that challenge long-term sustainability. Our results underscore the importance of management strategies to address challenging demographic rates. Efforts to mitigate the risks and effects of population decline and maintaining the myriad benefits white oak provides to eastern US forests, especially in the context of climate change and shifting species ranges, benefit from a deeper understanding of the ecological and socioeconomic factors driving these results.
