soil generally throughout this type, is deeper, more loamy, and 

 contains more moisture than that found in the other types. 



The hemlock type is found largely on the thinner and more 

 stony soils, and drier situations. The same species are found 

 in association, wth the exception of Sitka spruce, which is absent, 

 and a few scattered White pine. This type occurs more commonly 

 on steeper slopes and higher up on the ridges, but in general 

 topography it is much the same as the cedar type. Hemlock 

 constitutes 46 per cent, Douglas fir 24, cedar 21, and Amabilis 

 fir 9 per cent of the stand by volume. Over much of this type 

 surface fires have run through the mature timber, especially on 

 the Trapper Creek drainage. Only about 77 per cent by area is 

 mature, 15 per cent being under 100 years old, and 8 per cent 

 from one to 20 years. This youngest growth is on old burned-over 

 areas, now reproducing to hemlock, fir and cedar, with hemlock 

 in predominance. The condition of the timber for all species 

 is poorer in this type than in the other two types, with the 

 exception of the cedar, which is good. The hemlock is in poor 

 condition and shows evidence of unsoundness, though the trees 

 have clear boles and generally well formed crowns. 



In the Douglas fir type, which occurs on the drier slopes and 

 tops of ridges and knolls, associated with hemlock, cedar and 

 scattered Amabilis fir, the soil is much the same as in the hem- 

 lock type, though it tends to be somewhat deeper and more 

 loamy. There is practically no immature timber in this type. 

 The Douglas fir occurs as two stands, much of it being over- 

 mature and decadent, averaging from 90" to 100" d. b. h. with 

 occasional trees 120" d. b. h., and mingling with the over-mature 

 timber is a thrifty mature stand of fir averaging about 40" d. b. h. 

 Of the whole stand, 47 per cent is Douglas fir, 29 is hemlock, 22 

 is cedar, and 2 per cent Amabilis fir by volume. There is some 

 evidence of butt rot, but very little of fungus attack. The cedar 

 and Amabilis fir are in good condition, whereas the hemlock, 

 as in the other types, has a considerable amount of defect. Much 

 of the Amabilis fir is still immature, and is fairly good as to- 

 quality and is clear boled with well defined crowns. 



Over the greater part of the area there is only a very scattered 

 reproduction of hemlock and cedar, with practically no fir. There 

 are certain portions, however, in limited areas in the upper 

 slopes of the hemlock type where there is a dense reproduction
