Removal and degradation of bottomland hardwood forests (BLHW) in the southern United States has been extensive over the past 200 years. Large mast-production is crucial to the survival of some high-priority wildlife. A two-year study monitored survival and growth of planted seedlings receiving different levels of overhead density reduction and competition control. Competition control did not increase survival of the oak species. Pecan seedlings receiving the weed barrier mat treatment had greater survival than pecan seedlings receiving the herbicide treatment, or those receiving no competition control. A greenhouse experiment examined hardwood seedlings’ response to two-phase flooding/drought treatments to measure the effects of flooding and drought stress, and the disturbance sequence on survival, growth, and physiological processes of seedlings. The flooding treatment reduced photosynthetic rates on most of the measurement dates. Stomatal conductance and transpiration were higher for pecan than bur oak on most of the measurement dates.
