“…The valley oak saplings in our study experienced rapid post‐burn growth for 2 years following the fire, essentially recovering their height losses from the burns. Several other studies (McClaran & Bartolome 1989; Brose & Van Lear 1998; Bartolome et al 2002; Swiecki & Bernhardt 2002) have also found that oaks experience accelerated postfire growth. Accelerated growth in other studies did not result in burned oaks returning within a few years to the full height they would have been had they not been burned, perhaps because of shading from overstory trees (Dey & Hartman 2005).…”

Woodland restoration sites planted with Quercus lobata (valley oak) often have serious invasions of nonnative annual grasses and thistles. Although prescribed fire can effectively control these exotics, restoration managers may be reluctant to use fire if it causes substantial mortality of recently planted saplings. We studied the effects of prescribed fires on the survival and subsequent growth of 5-and 6-year-old valley oak saplings at a research field near Davis, California. One set of blocks was burned in summer 2003 at a time that would control yellow star thistle, a second set of blocks was burned in spring 2004 at a time that would control annual grasses, and a third set was left unburned. Very few oaks died as a result of either fire (3-4%). Although a large proportion was topkilled (66-72%), virtually all these were coppiced and most saplings over 300 cm tall escaped top-kill. Tree height, fire temperature, and understory biomass were all predictive of the severity of sapling response to fire. Although the mean sapling height was initially reduced by the fires, the growth rates of burned saplings significantly exceeded the growth rates of unburned control trees for 2 years following the fires. By 2-3 years after the fires, the mean height of spring-and summer-burned saplings was similar to that of the unburned control saplings. The presence of valley oak saplings does not appear to preclude the use of a single prescribed burn to control understory invasives, particularly if saplings are over 300 cm tall.

“…The influence of natural fires on forest dynamics of the central Appalachians may be disproportionate to their frequency, because trees are more sensitive to growingseason fires than to dormant-season burns (Brose and Van Lear, 1998;Dey, 2002). Consequently, growing-season fires typically cause higher tree mortality.…”

This paper uses records of wildland fire to investigate the contemporary fire regime on federal lands in the central Appalachian Mountains of Virginia and West Virginia. During the study period , 1557 anthropogenic fires and 344 natural fires occurred on these lands. Most were small, low-intensity burns. However, fires of moderate to high intensity also occurred, and because of their larger sizes they were responsible for most of the area burned. Fire size also differed between natural and anthropogenic fires (median size 1.2 ha vs. 0.4 ha). A few of the anthropogenic fires were quite large, however (up to 6484 ha), whereas the largest natural fire measured only 1188 ha. Anthropogenic fires burned more area than natural fires and consequently they had a shorter fire cycle (1196 years for anthropogenic fires, 6138 years for natural fires). These fire cycles appear to be much longer than in the past, prior to fire suppression. Nonetheless, despite suppression efforts, a substantial amount of fire activity occurred during the study period when conditions were sufficiently dry. The dry conditions of spring and fall were especially favorable for burning. Moreover, on an interannual level, drought had a strong influence on the amount of fire activity. [

“…The lack of Quercus regeneration is a major issue facing forest managers in eastern North America (Abrams 1992, Brose and van Lear 1998, Royse et al 2010. The understory and subcanopy of many forests are dominated by shade tolerant or mesophytic trees that are potential Quercus-replacement species (Lorimer 1984, Abrams 1998).…”
