“…Indeed, retrospective studies of old-growth forests in eastern North America have revealed that many of these systems experienced multiple intermediate-scale disturbances which had marked impacts on development and succession (e.g. Oliver and Stephens, 1977;Orwig et al, 2001;Fraver and White, 2005;Hart et al, 2008Hart et al, , 2012Pederson et al, in press). Furthermore, research has indicated that the frequency of intermediate-scale disturbance in the Eastern Deciduous Forest Formation of North America may have declined over the past three centuries and this decline may in part explain widespread successional patterns throughout the region .…”

“…There is no expectation that a 100% of the sampled stems demonstrate a release (Nowacki and Abrams, 1997;Pederson et al, 2008). In most situations the 25% cutoff is a conservative value and a much higher percentage of trees demonstrate a release event during a stand-wide disturbance (Busby et al, 2008b;Hart et al, 2008). Therefore, the variation of within-tree release identification will be unlikely to substantially alter the identification of large-scale stand-wide disturbance events and in most situations it will be acceptable to continue Fig.…”

“…Identifying pulses of increased growth within tree-ring series is the primary method for assessing canopy disturbance [20,37,41,42]. Release events were determined to be periods in which raw-ring width was ≥25% (minor) or ≥50% (major) of the 10-year preceding and superseding mean [37], sustained for a minimum of three years [39,40,43]. Because we utilized two cores per tree, analyses were combined to create a single composite disturbance history for each individual.…”

Multi-cohort stands are increasingly recognized and valued because of their biological functioning, biological diversity, and resistance and resiliency to perturbations. These forest ecosystems are epitomized by multiple age classes, and often contain multiple canopy layers, a range of tree size classes, and large amounts of woody debris. Disturbance history reconstructions in multi-cohort stands provide an understanding of the processes that create these systems. In this study, we documented structure and composition, and used dendroecological techniques to reconstruct disturbance history on a 1 ha plot in a multi-cohort hardwood stand in the Fall Line Hills of Alabama. The stand was dominated by Quercus alba L. and Liriodendron tulipifera L. Mingling index and stem maps indicated that most species were well dispersed throughout the stand, with the exception of L. tulipifera and Carya tomentosa (Poiret) Nuttal, which were relatively clustered. The oldest trees in the stand established in the 1770s, however, the largest recruitment event occurred ca. 1945 in conjunction with a stand-wide canopy disturbance. We posit that spatial heterogeneity of canopy removal during this event was largely responsible for the observed compositional and spatial complexity documented in the stand. In addition to the 1945 event, we recorded another stand-wide canopy disturbance in 1906 and 84 gap-scale disturbance events from 1802 to 2003. The conditions documented in the stand can be used as a benchmark to guide the creation and maintenance of complex multi-cohort stand characteristics, an increasingly popular management goal.
