already allow for the cost of restoring a 
stand by planting, which is probably 
considerably greater than the actual 
intangible loss. No additional value, 
therefore, has been allowed for “ in¬ 
tangibles, n except in the case of brush- 
land and grassland, and subalpine 
areas that do not produce merchant¬ 
able timber, and the southern Califor¬ 
nia hardwood bottomlands type, that 
has small commercial value and a very 
great intangible value. For these 
types, arbitrary intangible values were 
assumed. Except in the case of the 
Southern California stream bottom 
type, it was also assumed that very 
little or no damage would be done to 
the intangible values by fires covering 
less than 40 acres. In this type, even 
small fires, if they destroy the cover, 
do considerable damage, even though 
natural restocking quickly follows, and 
the damage where stands of mature 
trees are destroyed is at least as great 
as for younger stands, regardless of the 
timber value. 
TOTAL VALUES 
The standard total destructible 
values per fully stocked acre of young 
growth of the different types and in 
the several regions have been given in 
Table XVII. For the use of field 
officers within a given region, these 
values are not as complicated as they 
may appear here, because any one 
officer will have to consider only the 
figures that apply to his particular 
region, and to the types which are 
found on his particular district.
