S. K. HYUN 



The average tree in natural stands in Taiwan acquires a DBH of 

 25 cm and a height of 15 m in 50 years, thus showing a better 

 growth potential than natural stands of P. koraiensis. 



The wood properties are in general similar to those of P. 

 koraiensis being heavier, stronger in physical strength and 

 higher in durability than the wood of P. strobus.

RANGE AND FOREST TYPE 



The natural range (Fig. 1) of P. koraiensis covers northeastern 

 Korea from 39°N latitude, and extends into Manchuria through Kirin, 

 Heilungkiang, and Primorskays up to southeast Siberia around 54°N latitude. 

 It occurs sporadically on high mountains in south Korea and in central 

 Honshu and Shikoku of the Japanese islands (Critchfield and Little, 1966) .
