S. Redžić, S. Barudanović: THE PETTERNS OF DYVERSITY OF FORESTVEGETATION OF THE CRVANJ ...Šumarski list br. 5–6, CXXXIV (2010), 261-274
The analysis of floral elements spectrum– Analiza spektra flornih elemenata


In the structure of forest vegetation 135 plant species
have been found (Graph 1).The richest is thermophillos
community Quercetum petraeae-cerrisand
Querco-Carpinetum. Going to colder habitats in higher
position number of plant species has decreasing tendency
(Graph 1).


The 14 categories of floral elements have been
found in floristic composition of forest communities on
the Crvanj Mt. (Tab. 2).


To Dinaric floral element belongs only one species
found in the association Quercetum petraeae-cerris.
Species of Balkan floral element are present in all asso-

ciations with interval of 5 % (Quercetum petraeae-cer-The presence of these floral elements shows the siris)
to the 10 % (Phyteumo-Fagetum). Species of south-gnificant difference in comparision to forest communi-


European distribution are dominant
Seslerio-Fagetum sylvaticae.

1993;Solomakha,1966).


The species with subalpine floral
element show significant increa


sing in spectrum, with increase of
altitude.They are most abundant in
the association of subalpine beech
forests (29 %). Similar relations ha ve
been found in species of Euroasiatic-
suboceanic floral element.
With decrease of altitude, number
of species of northeastern-Euroasia tic
and sub-Mediterranean floral
ele ment increases. Sub-Atlantic floral
elements is most abundant in
mountain beech forests.

parameters show intermediate
