the national forests is assumed to amount to about 
450 million feet in the first decade and to increase 
to 2.25 billion in the third. According to these 
assumptions, by 1963 the 46.1 billion feet of tim- 
ber on the national forests in 1933 will be reduced 
to 45.8 billion and the 57.7 billion on other land 
in 1933 will be reduced to about 30 billion feet, 
depletion being practically equalled by growth on 
the national forests but being greatly exceeded by 
it on other lands. 
OREGON COAST DISTRICT 
The average annual cut in the Oregon coast dis- 
trict of trees of sawlog size used for all purposes of 
570 million feet in the period 1925-33 was about 7 
percent of the total regional cut and fairly evenly 
divided between the north and south units. Annual 
lumber production was about 540 million feet 
(1925-34 average) with a cut of 390 million feet 
in 1934. By 1933 the production of logs had 
dropped to 270 million feet, or 6 percent of the 
regional total. 
With the exception of Port Orford white-cedar, 
there will be no shortage of logs for local industries 
in this district for at least three decades. The 
assumed depletion in the district, which increases 
in each decade to 1963, would leave 15 billion feet 
The pre- 
depression annual cut of Port Orford white-cedar 
was about 70 million feet. The total stand of this spe- 
cles is not much more than 1.1 billion feet, of which

something more than 750 million feet is in private

Cessation of the exporting of Port Orford white- 
cedar logs would materially lengthen the life of the 
local industries dependent on them, since during 
the period 1928-33 the logs exported amounted to 
about 30 percent of the total quantity cut. 
For the district as a whole the depletion assumed 
in the survey for the period 1933-62, increasing in 
each decade, would not exhaust the class I timber. 
However, as in any other forest district of the region, 
dividing the remaining supply of class I timber by

the past average annual cut of logs does not neces- 
sarily give an indication of how long the wood using 
industries in the district may be assured of a supply 
of raw material. Even where a considerable vol- 
ume of timber is at present available, if the mill 
owner does not own this timber he may have no 
guarantee of a continuous supply. 
The total cut of some 33 billion feet in this dis- 
trict during the period 1933-62 is assumed to in- 
clude less than 1 percent cut on the national forests. 
The national-forest timber in the northern part of 
the district will not mature by 1963, and that in the 
southern part presumably will still be economically 
While the timber volume 
on lands other than national forests is calculated to 
decline from 52.5 billion feet (log scale) in 1933 to 
30.1 billion feet in 1963, national-forest timber is 
calculated to increase from about 15 billion feet in 
1933 to slightly more than 19 billion feet in 1963. 
The disastrous Tillamook fire of 1933, located 
mostly in the Oregon coast district, particularly 
affected the wood-using industries on the Columbia 
River, since probably at least three-fourths of the 
10 billion feet of timber burned would have been 
manufactured in Columbia River mills. Of the 
remainder, part would have gone to Oregon coast 
Salvage 
on the burned area has lagged behind expectations, 
and of the total volume removed to date a con- 
siderable part has been green timber. At the end 
of 1937 only about 5 percent of the timber burned 
had been salvaged.

boundaries of the burn have become tax delinquent, 
and even though assessed values have been reduced, 
the hazards of holding the timber make it doubtful 
that taxes will be paid on much of the burned area 
after 1940 or 1945. At current salvage rates the 
most that present owners can expect to recover be- 
for relinquishing their equities is about 2 billion 
feet. By about 1945 Tillamook County may own 
the greater part of the 7 or 8 billion feet that will 
remain uncut, unless the State or Federal Govern- 
ment takes over the area before that time. 
A study of deterioration of fire-killed Douglas-fir 
(7) showed that by the eighth to tenth year after 
fire killing, salvage for lumber logs is practical only 
for large slow-grown trees 50 inches d. b. h. and 
more. On the Tillamook burn Douglas-fir com-
