Mechanism
When the space can be done by the fallen dawn tree by deforestation
and the typhoon, etc. because the cryptomeria germinates in the place
where sunlight strikes in the intolerant tree, a new cryptomeria puts
out the bud with various tree kinds. This is a first step where the
cryptomeria of nature grows up.
As for YAKUSHIMA, because the replenishment of indispensable moisture
for the growth of the tree because it is rainy much and fogs is easy,
the cryptomeria is growing also on the stump and the fallen dawn tree
though only the one that the struggle for existence was overcome will
grow up in a big cryptomeria. This is called the stump update and a
fallen dawn tree update, and it is possible to see comparatively
easily in YAKUSHIMA.
This regards the cryptomeria in old times, and Ki is done, and the
every one is regarded that it is because the cryptomeria updated it
to the space with a wide the mark all together though the cryptomeria
woods of about the 300th grader is seen in the surrounding of the
Wilson stock and the flower mountain and KOHANAYAMA, etc.
Update on fallen dawn tree
It thinks about age of a tree KOSUGI of 1000 years or less, so-called
ecosystems of children of the Yaku Japan cedar,
It rains much, and it is not few in YAKUSHIMA that the tree begins to
sprout from the moss that grows in the tree skin and the rock. It is
possible to meet the entertaining spectacle when observing it well.
There is no place that grows up newly in the woods etc. of KOSUGI
thickly blocked because a bright place it doesn't grow up in the
Japan cedar.
However, if the big tree falls because of the influence such as the
wind and rain of something, the place where the positive is hit can be
done.
The bud comes out when the Japan cedar seed falls on the bright fallen
dawn tree and it grows up. This is called an update on the fallen dawn
tree. The bud newly comes out on the fallen tree and it grows up.
I can feel vitality with a stout small, young bud on the fallen dawn
tree and the stump.
The update on the fallen dawn tree is a mechanism of the strange generation
change developed in a deep forest to exceed.
YAKUSUGI and KOSUGI
In the enforcement of national forest, everything of YAKUSUGI and
less than
1000 of the age of a tree from 1000 years or more has
been divided as KOSUGI.
When you compare YAKUSUGI with the cryptomeria in the inland
１、The infant age leaf is very hard and sharply sharp.
２、Bark is exactly smooth and ash brown has been.
３、Zai is a reddish brown, and has six time or more inland material resin.
The fragrance doesn't rot easily very much high.
４、The amount of the minor is compared with the size of the trunk and there are
features such as few when becoming a big tree.
