Abstract

Throughout the deciduous forests of the eastern United States, oak (Quercus) regeneration has declined in stands historically dominated by oak species. In the Wisconsin Driftless Area, the level of decline in oak regeneration is variable and influenced by stand structural development, historical disturbance regime, abiotic site characteristics, and historical land-use legacies. This research aims to elucidate the relative importance and site-specific nature of the factors influencing oak regeneration and identify interactions between drivers. To document stand succession, development, and factors influencing oak regeneration, we collected forest inventory and dendrochronological data from 11 sites distributed throughout the region. The stages of structural development identified across sites included pole, mature-sapling mosaic, mature, early-transition old-growth, and steady-state old-growth. Structural complexity was variable across the region but generally increased with advanced structural development. At all sites, oak regeneration was negligible, with significantly lower relative densities of oak species in the understory than in the overstory. Future analyses will use multivariate techniques to investigate the relationship between stand development, land-use history, disturbance history, abiotic conditions, and oak regeneration.
