Abstract (summary)

This project evaluates oak regeneration options, acorn production, and the effects of long-term greentree reservoir (GTR) management on the vegetative composition of a bottomland hardwood forest.

Vegetation data indicate the GTR overstory is dominated by overcup oak and willow oak. Overcup oak is the dominant species in the midstory and understory, while willow oak declined markedly. Results indicate a strong shift in species composition toward a flood-tolerant species association.

GTR flooding greatly reduced survival of planted seedlings. Efforts to regenerate oaks using midstory control and underplanting yielded promising results. Midstory control resulted in an adequate amount of light reaching the ground to facilitate oak regeneration. Underplanted seedlings exhibited good initial survival; however, flooding will likely limit survival.

Acorn production was good for both years. Trees with DBH between 55 and 65 cm produced the majority of sound acorns. Acorn production was likely sufficient to accommodate foraging waterfowl and natural regeneration.
