Abstract
Hillsides in the Kwanak arboretum area were composed mainly of coarse sandy loam having
relatively high proportion of rough weathered debris derived from the Daebo granite geologically.
Owing to heavy soil erosion resulted to shallow soil depth and heavy rock exposures, the growing
trees in this type of' surface soil are very poor in their growth. For woody plant vegetation
establishment in this montain area, it is urgent to recover the fertility of soil and the growth of
existing trees.
For this purpose, in spring and autumn season in 1983-84 the fertilization experiment was
conducted with the 4 principal native species(Pinus densiflora, Pinus rigida, Juniperus rigida,
Rhododendron schlippenbachii) growing in this denuded forest land, and the effects of fertilized
tree plots were more prominent than the control plot in both height and root-collar diameter
growth.
Therefore, the accelerating measures of vegetation rehabilitation through conservation of existing
trees and recovery of tree growth by forest fertilization practices, besides forest engineering measur
es and soil erosion control afforestation measures, could be acceptable as the measures for the
recovery of denuded forest land in Mt. Kwanak area.
