its upper to its lower end, and 5 km. from side to side. 
Although some local differences may be observed here, it is 
the Tsuga that controls the vegetation by so much as eighty 
percent, with much under-growth and with some additions of 
Chamcecy paris. This Chamcecyparis being tolerant of shade, 
can grow even in the dense forest of Tsuga. Picea polita and 
Pinus parviflora also intermingle here. 
Fig. 27. Conifer forest of Aogigahara, near the top of the Konuo pass. Conifers in the 
background are Picea polita, and Tsuga Sieboldii ; the deciduous-tree in the fore- 
ground is Alnus incana. (Photographed by the author.) 
Turning to the due north side, the Conifer formation 
stretches from 2000 m. down to 1500 m.; and presents a grand 
distant view making a belt around the peak. The predominating 
tree cn this side is Tsuga especially in the vicinity of Maru- 
yama, i.e. 10% of Tsuga and 20% of Larix. A little east- 
wards from here, we come to Yakikomi (cf. map.) where Larix 
predominates to such an extent that it ranges from 1500 m. up
