nost alepskog bora koji se bolje razvija u eumediteranu i crnog bora koji bolje
raste u hladnijoj zoni submediterana.


4. Nalazišta brucijskog bora u Istri i Kvarneru rasprostranjena su od 0 do
oko 400 m, najviše do oko 600 m n. v. Grubo uzevši, taj bor dobro uspijeva od
obale mora do oko 200 (300) m n. v.; na boljim staništima može se dobro razvijati
i do 400 m n. v. Na višim položajima, makar ponegdje može razviti veće
dimenzije stabala nego orni bor, vitalnost i kakvoća su mu uglavnom mnogo
slabiji.
U narednom članku razmotrit ćemo ekološke, biološke i ekonomske značajke
brucijskog bora na temelju istraživanja u makrostaništima i mikrostaništima.
Iznest ćemo i indikatore koji potpunije i razmjerno jednostavno omogućuju
izbor staništa za unošenje ove vrlo vrijedne četinjače.

PINUS BRUTIA TEN. — AREA AND SITES


Summary


In the Yugoslav area of the Mediterranean Basin the afforestations were made
in general with Austrian and Aleppo Pines (Pinus nigra et P. halepensis), very
little with Cluster Pine (P. pinaster), and only insignificantly with other coniferous
and broadleaved species. On the ground of investigations on P. brutia in the S. R.
of Croatia and with regard of ist characters, area and macrosites in comparison
to those of Austrian and Aleppo Pines, the following general conclusions may be
drawn:


1. Despite its similarity with Aleppo Pine, P. brutia is a definite tree species.
Owing to their interelationships these two Pine species have a great number of
different hybrids. Pinus brutia has developed different varities of which several
may be suited for forest economy, and the other (from the standpoint of growth
form, stocking density, crown breadth and colour) for the establishment of so-
called tourist forests.
2. The natural area of P. brutia in the Mediterranean is in its Eastern part, of
Aleppo Pine mostly in the Western part, and of Austrian Pine in the Northern part.
In Yugoslavia Pinus brutia has been spread only artificially, mainly on the territory
of Croatia, i. e. in the northern part of the Adriatic (mostly on Istrian peninsula)
and on the Islands of the Kvarner.
3. The stands, groups and individual trees in the mentioned part of the Adriatic
are about 70 years old. They are found in the Eumediterranean and the warmer
subJMediterranean zones. The most significant vegetation zone for the maintenance,
development and growth of the mentioned coniferous species is Carpinetum orientalis
croaticum. In this zone the volume production of P. brutia is low, developing
better in the warmer Eumediterranean, and also of Austrian Pine, which grows
better in the colder areas of the sub-Mediterranean.
4. Localities of P. brutia in Istria and the Kvarner spread from 0 up to about
400 m. altitude, highest to about 600 m. above sea level. Roughly taken, this Pine
species thrives well from the seashore up to about 200 (300) m. altitude; on more
favourable sites it may develop well even up to 400 m. Although on higher sites
it may sporadically produce larger stem sizes than Austrian Pine, its vitality and
quality are generally poorer.
The ecological, biological and economic characteristics of P. brutia and a list
of the reference literature will be given in the next issue of this periodical.
