Figure 2 DCA ordination plot of 52 vegetation samples. Samples are marked with the sym-
bols denoting the treatment (Z – abandoned land, G – forest). First and second
axes explain 11.6 % and 7.5 % of variability in species data, respectively.


Slika 2.DCA ordinacija popisa označenih po tretmanima (Z – zemljište u zarastanju,
G – šuma). Prva os pojašnjava 11,5 % a druga 7,5 % varijabilnosti podataka


o distribuciji vrsta po popisima.
cies per plot between forest and
abandoned land at p<0.05. But
there was a significant difference in
the average number of shrub species
per plot.


In forest there were mainly


(91.5 %) tree species individuals,
while shrub species represent only
8.5 %. On abandoned land the proportion
was more balanced, where
tree species represent 53.0 %, and
shrub species 47.0 % of the share.
In the forest area, Fagus sylvatica
was the most abundant tree species,
followed by Carpinus betulus and
Quercus petraea. For shrubs, Sambucus
nigra was the dominant species,
followed by Corylus avellana
and Cornus sanguinea. On abandoned
land, Carpinus betulus was the
dominant tree species, followed by
Alnus glutinosa and Acer pseudoplatanus.
Among the shrub species,
Cornus sanguinea was the most
abundant, followed by Corylus
avellana and Prunus spinosa.
