Capitolo 72
cutting in fetterses, while showing, I/you/he/she allow us to for example say, approximately five trees of each
diameter from 6 to 12 thumbs or thirty-five in everybody that are ended
6 thumbs. If the study of growth points out there that in 20 years the wish
you/he/she has been assistant 6 thumbs in diameter we can appraise a crop of
five trees each of classes that extend him from 12 to 18 thumbs. Really
the trial won't be so simple for the elderly and different trees,
doesn't grow with equal rapidity, and many other factors owe
is calculated with, but the general principle is to apply percentage of
knowledge of growth to the material on hand and study of this material
it is essential.
To foretell picked equal-elderly that am the result of supplying whole,
the acquisition of information of base and necessary it is as difficulty, or
this way, but its question is simpler far. What a the ground wish
is fully provisioned from natural or artificial he/she wants to say it has to be presumed,
but we can also suppose that the result will only be influenced from
normal place conditions and not from accidental condition of the
present forest. Therefore we use a table of product and not a growth
table. This can be served as actual measurement of according to existing
growth is standing of centuries different that try not only the growth
rates but also the number of trees that the natural one that it shade-becomes bald
trial results in to different periods of the life of forest. The
principal danger of inaccuracy in such information lies in to found him/it on
insufficient measurements or in to apply him/it where ground or the damp
conditions are greatly different. The error according to you/he/she can be protected
against, however, from use of figures of growth taken in conjunction
with him. For example, if an exposure of table of product 25,000 feet to the
acrid to 50 seed you/he/she is accompanied by an exposure that the
middle stand that represents is 125 tall to 50 years and its average
50-year-tree is 14 thumbs in diameter, the small investigation is
necessary to determine if in some determined place the growth
