ABSTRACT

The objective of this study is to estimate the effects of forest management activities on mortality rates and fuel characteristics of coarse woody debris for Pinus densiflora stands in South Korea. This study used 40 managed plots and 14 unmanaged plots from the 6th National Forest Inventory plots. The results indicated that mortality rates of the managed stands were about 1.6% while those of the unmanaged stands were about 5.3%. The amount of coarse woody debris affecting forest fire spread was 2.2TOE ha-1 for the unmanaged stands, while 1.6TOE ha-1 for the managed stands. According to the results of decay class analysis, the ratio of decay class I, the most vulnerable to forest fires, was 22% for the managed stands while 29% for the unmanaged stands. Therefore, the unmanaged pine stands had higher fuel loads for forest fire in terms of coarse woody debris and higher decay rates than the managed Pinus densiflora stands. This information could be very useful to understand forest fire fuels in coarse woody debris for Pinus densiflora stands in South Korea.
