Abstract

Natural regeneration of Korean pine (Pinus koraiensis SieboldZ (2) our spatial analysis indicated that seedlings are negatively correlated with saplings and exhibit a higher degree of clumping than saplings. Relationships of seedlings with mature pines and all sizes of other mature trees appeared random, whereas saplings were negatively associated with small, medium and large mature trees. Our findings suggest that the effect of forest composition on regeneration mainly occurred before the leaf expansion in late spring.
