Abstract - The Ouachita National Forest is restoring pine-mixed hardwood forests to a shortleaf pine-bluestem grass ecosystem through harvesting, midstory control, and the application of prescribed fire. Mean mass and volume of downed woody debris (DWD) in plots following initial harvesting and midstory-control were respectively 335 percent and 253 percent greater than in plots that had no restoration activities. Harvesting and midstory control also increased the mean DWD contents of C and N by 308 percent and 369 percent, respectively. The initial restoration fire reduced DWD mass in the shortleaf pine-bluestem plots by 27 percent and DWD volume by 28 percent. C and N contents in DWD were also significantly reduced by the initial restoration fire (26 percent and 32 percent) but were still 205 percent and 169 percent greater than in plots without restoration activities.
