Unthinned, pole-size loblolly pine (Pinus taeda L.) plantations in the South Carolina Piedmont were burned at different seasons under minimal wind conditions to evaluate the effects of fire intensity on crown scorch. Needle drop, an indicator of crown scorch, was significantly greater on areas burned with medium- to high-intensity fires than on unburned plots. There was a direct relation between bark char height, beyond a threshold value of 3 feet, and crown scorch. Scorched needles fell within three weeks following fire. Moderate crown scorch had no detrimental effects on survival and growth of trees in the upper crown classes. Complete crown scorch resulted in the death of 20 and 30 percent of trees in the codominant and intermediate crown classes, respectively.
