Supplemental Tables 
Supplemental estimates of average annual fire damage 
are shown for the national forests, for other lands, and for 
all lands in the Douglas-fir region as follows: Forest-land 
area covered and timber volume, log scale, lost by fire, by 
type and site quality, table 44; area deforested by fire, by 
type and survey unit, tables 45, 46, and 47; and timber 
volume, log scale, lost by fire, by type and survey unit, 
table 48. 
Net average annual rate of depletion from causes other 
than cutting, used in calculating assumed future depletion, 
is shown by type group in table 49. Assumed future decadal 
depletion from all causes is shown by district and owner- 
ship class in table 50. 
Rates used in calculating potential annual growth on 
conifer timber are given in table 51. 
Saw-timber data for some forest regions of the United 
States have been published in lumber tally rather than log 
scale. In order to facilitate comparison with those data, 
saw-timber volume for the Douglas-fir region is given in 
lumber tally in table 52. Lumber-tally values are given 
for cutting depletion in tables 53 and 54, for fire depletion 
in table 55, for assumed future depletion in table 56, for 
current annual growth in table 57, for potential annual 
growth in table 58, for realizable mean annual growth in 
table 59, and for periodic growth in table 60.
