• Many bottomland hardwood stands in southern Mississippi lacked management prior to Hurricane Katrina. Following removal of overstory oaks, no seed source was available to naturally regenerate these stands. Artificial regeneration became the most viable option, but information was lacking on how to successfully reestablish thousands of acres of bottomland forests quickly and successfully.Bareroot and conventional containerized seedlings of Nuttall oak (Quercus texana) and swamp chestnut oak (Quercus michauxii) were planted on two sites in southern Mississippi. After two growing season’s Nuttall oak exhibited similar survival to (93.4%), better groundline diameter growth (13.0 mm) than, and better height growth (68.8 cm) than swamp chestnut oak (92.5%, 6.6 mm, 43.9 cm, respectively). Bareroot seedlings had the highest survival (94.5%), best groundline diameter growth (10.3 mm), and best height growth (66.6 cm), though conventional containerized seedling survival (91.4%), groundline diameter growth (9.3 mm), and height growth (46.0 cm) were all acceptable. Considering seedling cost and overall performance, bareroot seedlings provide the most effective option for artificial regeneration on high quality bottomland hardwood sites.
