1950, and Fagetum croaticum abietetosum Horv. and Fagetum croaticum subalpinum
Horv. (Fagetum croaticum allietosurn Horv.). On the basis of these investigations the
following — as a general rule — can be concluded:


a) From Beech trees belonging to the subassoeiation Fag. cr. seslerietosum
(autumnalis) Horv., and somewhat elss from Beech trees belonging to the association
Fag. cr. calamagrostetosum Horv. (thermophilous Beech forests) were worked up
assortments white in colour, the so-called »white Beechwood«. The gross volume of
these trees — determined after Šurić´s volume tables — may be utilized on an average
in the forest (according to JUS-standard from 1955) with 86.48% including in
the utilized volume also short-cut billets of firewood (3—7 cm. mean diameter).


The average distribution of the assortments is as follows: veneer logs 6.54%,
peelers 9.92%, boule-logs 3.06%, grade I sawlogs 4.66%, grade II sawlogs 13.1070, and
grade III sawlogs 11.12%).


The share of sleeper logs was 16.36%, that of pitprops 4.74%, of pulpwood
10.20%, while the share of firewood (depending upon the grades) was 17.84(;,/o, and
that of short-cut billets of firewood 2.40%.


Beech trees belonging to this plant association yield high-grade timber.


b) From Beech trees belonging to the association Fag. cr. abietetosum Horv. on
certain exposures were worked up assortments white in colour (»white Beechwood«),
but, as a rule, the processed assortments are red in colour (»red Beechwood«), which
are inferior in quality to the »white« variety.


Beech trees of this plant association may be utilized in the forest (according to
JUS-standard from 1955) with 86.79% (including short-cut billets of firewood).


The average distribution of assortments is as follows: veneer logs 3.78´%, peelers
6.36%, boule-logs 0.67:%, grade I sawlogs 9.20´%, grade II sawlogs 18.12"/», and grade
III sawlogs 17.67s/».


The share of sleeper logs was 12.85%, that of pitprops 3.99%, of pulpwood 4.14%,
while the share of firewood (according to grades) was 20.89%, and that of short-cut
billets of firewood 2.33%.


Beech trees belonging to this plant association are as a rule of lower quality
than Beech trees belonging to the plant association mentioned under a).


c) From Beech trees belonging to the montane Beech forest (Fag. cr. allietosurn
Horv.) were worked up as a rule assortments red-black in colour (»red-black Beechwood
«), which are of lower quality than those of pure »red Beechwood«, and notably
inferior to the »white Beechwood« variety.


Beech trees of this plant association can on an average (according to JUS-standard
from 1955) yield 84.82% of assortments of wood in the rough (including short-
cut billets of firewood, 3—7 cm. in diameter).


In the yielded roundwood there occur neither veneer logs nor boule-logs. Peelers
participate with 5.41°/», grade I sawlogs with 9.72%., grade II sawlogs with 17.73%,
and grade III sawlogs with 8.91%.


The share of sleeper logs was 21.24%, that pitprops 2.72%, of pulpwood 3.10°/»,
while the share of firewood (according to grades) was 28.91%, and that of short-cut
billets of firewood 2.26%.


Beech trees belonging to this plant association are a sa rule of very poor quality,
and by far inferior to those originating from the previously mentioned plant
communities.


d) And, finally, on the basis of the performed investigations in 6 forest districts,
7 management units, and 15 compartments covering an area of about 700 ha., and on
2,499 Beech trees with a gross volume od 4,437 cu.m. — we can reckon (from the
standpoint of the global volume) with a utilization % of ca. 86 (if the gross volume
is determined afin the utilized volume).


Within the utilized volume we can reckon with the following percentage distribution
of assortments: veneer logs ca. 4%, peelers ca. 7%, boule-logs 1%, grade I
sawlogs ca. 8%, grade II sawlogs 17%, grade III sawlogs ca. 17%.


Further we can also reckon with the following assortiments: sleeper logs ca.
14°/», pitprops ca. 4%, and pulpwood ca. 5% the total volume of firewood (irrespective
of grades) ca. 21%, and short-cut billets of firewood ca. 2%.


In the total of the utilized volume logs (sleeper logs included) accounted for ca.
68%, while the share of the remaining assortments was ca. 32%. These data may
also be applied to other Beech stands growing under similar ecological and silvicultural
conditions.
