Water tables are expected to rise somewhat in the vicinity of planned impoundments along the Tennessee-Tombigbee Waterway. Where permanent flooding of timber is anticipated, tree mortality is expected and has been accounted for in the project planning process. However, where water table levels will be raised significantly but permanent flooding does not occur, the effects on forests are very unclear. This report identifies factors that may be pertinent in assessing this type of impact. The information presented here has been drawn from the scientific literature on species flood tolerance and related topics that provide insight on potential water table effects. This review concentrates on induced mortality and changes in growth rates of mature trees. Author
