Abstract
The 20th Biennial Southern Silvicultural Research Conference was held in Shreveport, LA, March 12–14, 2019. This conference provided a forum for silviculturists, researchers, and practitioners to exchange the latest research information on the ecology and management of southern forests. Of the 68 oral presentations and 35 posters presented during the conference, 44 papers and 6 extended abstracts were submitted for these proceedings. The papers cover eight topics, which include Forest Measurements and Modeling; Fire; Longleaf Pine; Soils, Disturbance, and Genetics; Hardwood Regeneration; Intermediate Management and Stand Development; Vegetation Management; and Shortleaf Pine. Papers and abstracts from oral and poster presentations provide managers with the latest research from universities, government agencies, and natural resource agencies.
