Reversing Mesophication Effects on Understory Woody Vegetation in Mid-Southern Oak Forests

Mesophication has reduced fuel-bed flammability in the Mid-Southern US, limiting the effectiveness of fire alone in promoting disturbance-adapted woody species. We applied combinations of thinning (none, 7, and 14 m 2 ha -1 residual basal area) and seasonal fire (none, October, and March) at three sites and monitored understory woody response from 2008 to 2016. In combination, thinning and burning had strong negative effects on some mesophytic species (Pinus strobus, Ostrya virginiana, and Fagus grandifolia) and positively affected many shade-intolerant and fire-tolerant species formerly suppressed under closed canopies. Such compositional shifts were greatest at our most xeric site, and were related to treatment effects on overstory and midstory density. Seedling density of Quercus spp. nearly doubled (+2,256 stems ha -1 ) from pre-to postmanagement. Sapling response was less dramatic; however, indicator and ordination analyses often associated mesophytic and disturbance-dependent saplings with unmanaged and managed treatments, respectively. Fire-season effects were subtle, but more species and greater understory densities were associated with March relative to October burning. Although some mesophytic species (Acer rubrum and Liriodendron tulipifera) responded positively to thinning and resprouted aggressively after fire, our results demonstrate how thinning and burning can initiate the reversal of mesophication's effects on understory woody vegetation.

In eastern North America, there are few stratified sites dating to the Late Pleistocene epoch (> 11,700 cal B.P.). Instead, researchers have relied on the distribution of surface sites and isolated finds to make inferences about how the early inhabitants of the region used the landscape. While proxies for modern recovery bias have been found to affect artifact recovery at a national scale, in the southeastern United States, I argue, they are poor predictors for the frequency of Clovis type bifaces (ca. 13,250–12,850 cal B.P.) from counties in the southeastern United States as reported in the Paleoindian Database of the Americas (PIDBA). Instead, counties with the highest density of Clovis bifaces are near sources of lithic raw material, and in particular the intersection of major rivers, physiographic boundaries, and lithic raw material sources. I contend that these locations could represent seasonal aggregation loci. Alternatively, they could reflect areas where lithic raw material is more readily available, which may have resulted in higher rates of artifact discard. Determining which of these hypotheses is a more accurate reflection of past human behavior requires that we untangle the degree to which the amount of time people spent at these locations was successive versus coeval.
