PINUS MONTICOLA DOUGL. 



At the Tokyo University Forest in Hokkaido, Pinus monticola shows a 

 brownish discoloration of the needles in winter to early spring. This 

 discoloration probably results from exposure to cold winds. When P. 

 monticola is planted behind windbreak trees, early growth is almost the 

 same as that of P. pentaphylla (Fig. 9) . Establishment of P. monticola 

 forests has just started. Perhaps it will be best if any large planta- 

 tions of this species are made in Honshu, rather than in Hokkaido.

 in Hokkaido, near Yamabe, Furano.
