Abstract: | Increased planting of hard mast oak species in the Lower Missouri River floodplain is critical as natural regeneration of
oak along the Upper Mississippi and Lower Missouri Rivers has been limited following major flood events in 1993 and 1995.
Traditional planting methods have limited success due to frequent flood events, competition from faster growing vegetation
and white-tailed deer herbivory. Results of early growth response of swamp white oak (Quercus bicolor Willd.) seedlings in relation to initial acorn mass and size, and early rapid shoot growth for seedlings produced by containerized
root production method (RPM™), are presented. Containerized RPM™ seedlings grown in the greenhouse under optimal conditions
demonstrate that seed size had no discernable impact on first-year root or shoot size. Seedling survival for the first two
years and acorn production for the first three years after outplanting are presented, comparing use of containerized RPM™
swamp white oak seedlings to nursery stock. Flood tolerant precocious RPM™ oak seedlings in the floodplain provide a source
of food for acorn-consuming wildlife ten to fifteen years sooner than oaks originating from natural regeneration, direct seeding
or traditional bare root planting. Compared to bare root nursery stock that produced no acorns, some RPM™ swamp white oak
seedlings averaged 4.3, 5.2, and 6.3 acorns/seedling in the first three years after fall outplanting.
