DOUGLAS-FIR SECOND GROWTH 
The small second-growth (9) and seedling and 
sapling (10) types occupy a total of 5.8 million 
acres including some of the most favorably located 
and productive forest land in the region. Stands 
of these types are almost always even-aged. ‘They 
are usually pure, averaging from 80 to 90 percent 
Douglas-fir in the region as a whole. 
The small second-growth Douglas-fir occupies 
3.7 million acres, mostly old burns. The stands, 
6 to 20 inches d. b. h., range from 20 to 120 years 
in age; on poor sites many stands reach 100 years. 
Less than half the small second-growth stands are 
well stocked (table 4). As a general rule those 
growing on old burns are better stocked than those 
growing on cut-over land, because practically all 
cut-over land has been burned over at least once 
and much of it several times. 
The stands on cut-over lands occur chiefly on 
areas that were logged in the early days of the 
lumber industry and that are easily accessible from 
industrial centers. ‘Topography usually permitted 
cheap logging. Undoubtedly these areas will be 
logged again before many of the more remote old- 
growth areas. ‘They are being logged already in a 
small way for poles, piling, fuel wood, and sawlogs. 
This premature clear cutting of small second 
growth is a short-sighted practice, but from present 
indications it will increase. Approximately two- 
thirds of the area involved is privately owned, 
chiefly by farmers and other local small holders. 
Such owners usually do not have the resources to 
carry timber for long periods. How to introduce 
forest-management practice in these second-growth 
stands is one of the critical forest problems in this 
region.
