Abstract
The relationship between competing vegetation characteristics (above and below ground dry weights, length and surface area) and loblolly pine (Pinus taeda) seedling characteristics were examined on a southern coastal plain soil of north-west Louisiana. Four site preparations techniques were used as treatments; chop and burn, windrow, fuelwood harvest, and fuelwood harvest followed by an application of herbicide. The more intensive site preparation treatments (chop and burn, windrow, and fuelwood harvest followed by a herbicide) had less root and above ground competition than the fuelwood treatment. The fuelwood treatment ranked lowest in pine seedling height, ground line diameter, pine root length, and pine root surface area and highest in terms of competing vegetation characteristics. Regression relationships between pine roots and competing vegetation root characteristics indicated that seedling ground line diameter is inversely related to quantities of competing vegetation roots.
