Abstract
The 21st Biennial Southern Silvicultural Research Conference (BSSRC) was held on March 16-17, 2021, in a virtual format. The BSSRC is designed as a forum to exchange silvicultural information between researchers, land managers, forest industry, and graduate students. From the 64 oral presentations and 22 posters offered at the conference, 26 papers and 24 extended abstracts were submitted to these proceedings. The submissions were organized into seven topics, which include Prescribed Fire; Bottomland and Riparian Forests; Loblolly Pine Management; Natural Disturbances and Climate Change; Longleaf Pine Management; Upland Hardwoods Management; and Shortleaf Pine Management. Collectively, the work presented in this manuscript provides a synopsis of the latest silvicultural research conducted in the Southeastern United States.
