“…This difficulty in creating open-canopy conditions through prescribed fire alone has also been seen in other eastern oak-dominated forests where prescribed fire was used to promote oak reproduction (Brose et al 2013;Holzmueller et al 2014;Hutchinson et al 2012aHutchinson et al , 2012bIverson et al 2008). This may mean that commercial or noncommercial thinning may be needed to meet the goals for open-canopy conditions (Waldrop et al 2016).…”

On the George Washington and Jefferson National Forests, managers have used prescribed fire to create and maintain early-successional and open forest conditions across large areas. We used a landscape-scale and image-based approach to assess the extent that prescribed fires, including repeated fires, have created these forest conditions and put the results in context of the new George Washington National Forest management plan. At the landscape level, early-successional forest made up an average of 5 percent of burn unit area after one burn, 9 percent after two fires, 17 percent after three fires, and 14 percent after four fires. On average across all burn unit acreage, open forest made up 5 percent of the area after one burn, 7 percent after two burns, 9 percent after three, and 8 percent after four fires. The forest plan desired condition of 12 percent of the area in early-successional forest was met after three or four fires and was exceeded in some individual burn units. It is harder to achieve open-forest than early-successional conditions using prescribed fire alone. We also examined possible drivers of canopy gap creation in these forests. Vegetation type and heat load index, a topographic-based measure of solar radiation received by a site, were important predictors of where canopy gaps formed after prescribed fire.

“…In the absence of successful regeneration with fire alone, additional treatments have been implemented, e.g., harvesting, thinning, oftentimes in combination with fire, to stimulate oak regeneration. In some instances, this has proven to be a successful strategy although evidence suggests that oak regeneration may still be below desirable levels following treatment, particularly on productive sites [12,[15][16][17][18]. Furthermore, the impact of these treatments on residual oak midstory stems, trees that are too small to harvest and retain in thinning but may be damaged by fire, is unclear.…”

The lack of desirable oak (Quercus spp.) regeneration on upland sites is a problem in the Central Hardwood Region. While the reintroduction of fire, thinning, and/or harvesting has been proposed as a solution to increase oak regeneration, these treatments may have limited impact on productive sites, and the effects on the growth of residual midstory oak stems is not clear. This study examined the regeneration response and growth of residual midstory white oak (Quercus alba) stems in a mature, oak-dominated, upland forest following four treatments: (1) burn, (2) thin and burn, (3) harvest and thin and burn, and (4) no treatment (control) at Trail of Tears State Forest located in southern Illinois. Results indicated there was no significant difference in oak density among treatments for any regeneration size class. In addition, none of the treatments resulted in a radial growth release in residual midstory white oak stems. These results suggested these treatments may need to be modified to increase oak regeneration on productive sites and indicated that there may not have been enough time since treatment application, or treatments may not have been intense enough, to release midstory residual stems.
