Survival and growth of planted loblolly pine seedlings on a severely rutted site
1995
Survival and growth of planted loblolly pine (Pinus taeda L.) seedlings on a severely rutted site were evaluated over a 3-year period. The soil rutting caused by wet weather logging of the previous stand was divided into three categories of severity (severe, moderate, and light). Four plots, each containing 15 planted seedlings, were monitored for each of the severity categories. Seedling survival was actually greater in the severely rutted plots, probably because competition was reduced by the logging disturbance. However, during the second growing season, height and diameter growth of seedlings in the severely rutted areas was 26 and 21%, respectively, less than that of seedlings in the other two categories. By the end of the third growing season, cumulative height growth was 17% less on the severely rutted plots than on the other two categories.
