Flooding Effects on Southern Forests
Abstract:Spring floods in the lower Mississippi Valley can improve growth of dominant, vigorous hardwoods, primarily by supplying additional water later in the growing season. Flood-resistant hardwoods are damaged where silt and sand are deposited to depths of three or more inches, where soil conditions are adverse, and in depressions where water does not leave promptly. In these areas, mortality may occur over the next four years. Young seedlings of resistant species die back if inundated after they leaf out, but many will sprout from surviving rootstocks. The pines and many hardwoods in uplands behind flood control dams are not tolerant of flooding. There, high water for just a few weeks during the growing season may cause severe mortality.

- The Journal of Forestry is the most widely circulated scholarly forestry journal in the world. In print since 1902, the Journal has received several national awards for excellence. The mission of the Journal of Forestry is to advance the profession of forestry by keeping forest management professionals informed about significant developments and ideas in the many facets of forestry: economics, education and communication, entomology and pathology, fire, forest ecology, geospatial technologies, history, international forestry, measurements, policy, recreation, silviculture, social sciences, soils and hydrology, urban and community forestry, utilization and engineering, and wildlife management. The Journal is published bimonthly: January, March, May, July, September, and November.
