Capitolo 34
an excellent illustration. In the inside states this kind
it reproduces under cover to of the extension, because there is a stronger
light average in the whole year and because the stand is not this way
dense. In the Douglas typical fir forests of Oregon and Washington,
discussed in this book, it never does this way. While hemlock, cedar
and the white poverty of fir can be abundant, Douglas young plant of fir
you/he/she is seen except in scorching, slashings, roads or open stains rarely
in the wood. And the trees of fir that compose the dominant stand are
of almost the same age.
How, did it make this equal-aged forest of fir then, do you start? Poll nearby
it will practically always find the answer in fragments of charred
wood. A long time ago another similar forest occupied the earth up to that
lightning or the fire of an Indian started a new cycle. Possibly going again
swept scorching the area a lot of times in front of seeds wind-without breath started
you start groups of advance of fir that, when fifteen or twenty years
old, they bore fruit and they filled the empty spaces among them. Perhaps
the destruction was not trees so suits and sopravviventi made the trial
a more express. Except in the greater forests, where he/she remains
some original stand has to decompose completely street, the history in
both case can be read in ancient protuberances and you/he/she can be fallen trunks.
However supposes that fire, you/he/she had not come to help the fir in to perpetuate
it? Also, this that we can respond from the signals today. Each
Woodsman northwest knows lines of different ransom (usually small
because fire has been almost universal) covered with the great old hemlock,
white fir and cedar, with here and there a giant and dying fir, perhaps,
but only mainly showing occupation of fir rotting fetterses and trunks. No
signal of fire is seen. When this forest of fir average was approaching himself/herself/itself
you grow old, the shade that kind that brings has started to appear under of him. As the
firs started to crowd out, the later comers they shot above with
