PINE OF SUGAR (_P. Lambertiana_)
This extremely precious pine, commercially limited to Oregon and
Mountains of California, are difficult in its choice of the conditions. Not
a carrier of frequent or prolific seed, insists still on a loose dampness
seed-bed and he/she prefers the natural floor of earth burn-ended forest. It
you/he/she cannot sustain the drought when young and it omits on northern and fresh slant
young plant you/they can be killed or shabby from exposure to the full light of the sun. On
the contrary one that requires lighter as more old man grows and
you/he/she will be suppressed or you/he/she will be killed if incapable to assure him/it. Under natural
conditions him perpetual better filling open places in
the forest.
For the reasons on, pine of sugar is naturally a component of mixed
forests and it is doubtful if you/he/she will be grown with success as
a pure stand. Unfortunately, also, cutting in fetterses methods that are both
the simplest and more favorable to the reproduction of his/her partners
you/he/she can be discouraging to sweeten reproduction of pine. Nevertheless, his/her
value guarantees strong efforts to favor him/it and is a matter, where
young pine of considerable sugar exists, against both clean cut
or the use of fire.
The Service of Forest for that the a lot of authority of the discussion on
of this kind was taken, he/she offers the general and following contour
for management in California:
"Since the forests in which sugar and yellow pine happen various greatly
in composition, the method of treatment has to also vary. For this
the types of forest already separate you/they can form a base.
"On the lowest portion of the sugar type of pine-yellow pine, where
forms of pine of sugar but a small proportion of the stand, only the yellow
pine should be considered for the future forest. Entirely marketable
pine of sugar can be removed therefore. It will be necessary to permission
only some trees of seed of yellow pine to supply the earth, even if
it will be usually a wiser policy to leave an equitable stand, since then
