optimum just there on the very forest edge and can be found only sporadically
inside a canopied forest stand.


The shrub associations on the forest edge are very important for forest
protection against the wind, by reducing its force and by changing its direction,
and at the same time they keep moisture and precipitation and reduce
pollution of the environment. The shrub species are also very important in
fighting erosion, so they are used in the development of various surfaces
obtained after the construction of roads, railway lines, transmission lines, etc.
In that, special attention must be paid to plant autochthonous shrub species
whenever possible, which will fit better in the environment and in some places
will present and form a succession stage toward the forest.


So far the forest edge shrub associations have not been researched much in
Croatia. Thus, Horvat (1962) researches the forest edges and describes the
associations Corno-Ligustretum croaticum awt/Berberidi-Rhamnetum fallacis.
However, in the work no releves or tables are given (cf Barkman etal. 1986,
Art. 7). Later, the table was published (Horvat et al. 1974), but the name with
the geographical indication Corno-Ligustretum croaticum was chosen, that is
not in compliance with Code (cf. Barkman et al. 1986, Art. 2c). This association
with three releves was renamed by Trinajstić & Zi. Pavletić (1991)
who designated it by the name of Corno-Ligustretum, however they did not
determine the nomenclatural type (cf. Barkman et al. 1986, Def 8), namely
they did not refer to the description of the association Corno-Ligustretum
croaticum (Horvat et al. 1974; Barkman et al. 1986, Art. 2b). In the further
analysis it will be necessary to determine the resemblance of this association
to the association Ostryo-Cornetum sanguineae Čami 1997, which was
described in the south-eastern Slovenia (Čami 1997).


The research of the shrub forest edges was carried out in June and July
2001 in Central Slavonia in the vicinity of the villages Musić, Levanjska Varoš,
Slobodna Vlast, Ovčara, Hrkanovci, Majar (near Đakovo) and Djedina
Rijeka, Imbrijevci, Paka (near Požega), (Fig. 2). A total of 10 releves was
made (Tab. 1).


Consequently, the researched forest edge shrub vegetation in Slavonia can
be divided into two groups, namely into the group with the mixed species of
classes Salicetaea purpuraea and Rhamno-Prunetea (Tab. 1, releves 1-8),
which we included in the alliance Šalici cinereae-Viburnenion (Pas. 1964)
de Foucault 1991, and into the group where dominant are the species of
class Rhamno-Prunetea (Tab. 1, releves 9-10), which we included in the
alliance Prunion fruticoae Tiixen 1952.


The research was made in compliance with the standard Central
European method (Braun-BIanquet 1964). On all releves two numerical
analysis methods were carried out - the cluster analysis and the multidimensional
scaling. According to the floristical (Tab. 1) and numerical (Fig. 1)
analyses, we decided to divide the releves in two associations inside which
dominant is the subspecies Prunus spinosa L. ssp. dasyphylla (Schur.)
Do min. One association occurs in thermophilous habitats and is known
under the name of Crataego-Prunetum dasyphyllae Jurko 1964 (releves 9
and 10). The second association occurs on more humid habitats with another
combination of species and presents a new association designated by the
name Viburno opuli-Prunetum dasyphyllae Čami, Franjić et Škvorc
2002 (releves 1-8).
