Capitolo 50
enough it uniformly represented, succeeded in reproduction, and not this way
dense as you/he/she is ideally adapted for introducing the mechanical difficulties,
to this form of management. The important fundamental principle is
what, since for one period of his/her life the individual and normal tree
you increase in wood production and then the rebates, it is the bad economy
to cut him/it while you/he/she is quickly growing still or to allow him/it, later
slowing down, to occupy earth that anchors would be used by a tree
in the vigor of production. For example, if to 100 old it
it contains 500 feet of axle, you/he/she has made the average of a sum of 5 feet,
one year in all life of his. If to 125 old it contains but
560 feet, the middle increase will be but 4-1/2 feet for year.
It won't give equal return for the ground, the damp and light
it monopolizes during these 25 years. To the same duration, probably
I am near there until here the young trees of which what you/they have made the average under
the maximum one, but if you/he/she is released by his/her competition it will imitate before
for one period at the end of which they will give a greater annual plant
you return that if you/he/she is currently cut. It would be as the bad economy to cut
these today as to save the end-mature tree. In short, the production
some forest is not only sustained, but indeed it increased, from
removing the greatest trees to only the correct duration; and you/he/she has decreased
not taking out still the young trees one to the natural age of
greater bad annual increase or able artificial stimulation
becoming bald.
Studying the of age relationship to production in the particular one
place, the proportion of classes of different age and also finding
the middle and approximate diameter to which it corresponds to the age
what he desires to cut, the professional forester can do a lot a
accurate selection of the trees that you/they can be removed to the better advantage
currently and you also mend the time and produces some next cut.
