1989
Woo B.M. | Lee H.H.
To investigate the effects of forest fire on the change of vegetation and soil conditions by the lapse of time, the 5th soil survey and vegetation analysis were carried out in July of 1988 at the rocky areas of Mt. Kwanak, where ground fire broke out 5 years age. Three-year increasing trends of organic matter content, the value of pH, and total nitrogen content stabilized after the restoration of the vegetation. By the comparison of the occurrences of the species for 5 years after the forest fire, woody and herbaceous plants were categorized into 4 groups, i.e., invasive, sensitive, tolerant, and neutral species to the forest fire. Although such diversity indices as the species diversity and similarity index indicate that the restoration of damaged vegetation to the original species composition was proceeded for the period, the restoration of vegetation to the original crown closure and tree growth was not proceeded yet.
