Capitolo 52


Under this system that perhaps goes again cuts you/he/she can be done to periods of
30 or 40 years, taking every time the trees that I/you/they are passed
the least diameter since the last cut precedent. It is obvious,
however, that if the trial is to indefinitely continue protection,
it has to be absolute. The destruction of the young growth will stop the rotation
to the duration the oldest material sopravvivente is picked. To each
you cut the brush you/he/she should be prepared than with this end in sight. If the
stand is very thin you/he/she cannot add a lot to the danger of fire and,
especially if reproduction is difficult and asks for refuge,
better both left expansion on the earth to of the distance to be remained
trees. Otherwise, and this is the rule, you/he/she should be accumulated and
it usually burned. In this trial and in to cut in fetterses every effort owes
is done for protecting the young growth existing from damage. Earth's fires
now and you/he/she should be always in expectancy prejudiced.

We am considering therefore however, as to do more anymore the
of a stand of a lot of centuries, because of permitted continuous reproduction
from the light provisioning in an enough open forest. On the other hand,
yellow pine sometimes produces so a mature stand bad that there
it is few the young growth under of him, or also an old thin stand with
small reproduction or an invasion of pine of lodge-pole. This way
conditions are usually because of fire to of the period. In the first one
of these cases, the dense stand has usually been the result of a fire
what it didn't so entirely destroy his/her predecessor as to remove the
provisioning of seed, but sufficiently to afford more uniformly himself/herself/themselves light for a
picked dense of young plant that would happen in the normal forest.
These have been become bald out as the stand it grew old, but never to a
degree that allowed a lot of reproduction under of them. The natural one
cycle be starts again in duration, for toward the end of the life of
this heavy stand unusually, young plant they will start to gradually to appear
