Decline of the sessile oak [Quercus petraea (Mattuschka) Lieblein] in Bosnia and Herzegovina is increasing recent years. Investigation carried out in a sessile oak stand on the mountain Motajica (northern Bosnia) shows that both environmental factors (e.g. climatic changes, mismanagement etc.) and attack of the mistletoe Loranthus europaeus are responsible for this process.
Regarding climatic factor it is worth to mention that the year 2003 was extremely dry (Table 1). This very year drought index for this region was below 26 during eight months, and even below 25 during seven months continually (February-August). In addition, the minimum air temperature during previous winter (December 2002 to April 2003) was below 0 oC and coming down even to -22,5 oC in January 2003.
The mistletoe was present in all tree dbh. classes, but its occurrence increases with the tree diameter. Number of the infested trees over 70 cm was 77,8% (Table 3). The intensity of the attack measured according to the number of the mistletoe brooms per infested tree depends also on the dbh. classes (Table 5).
It is concluded that lack of a proper forest management was among the factors responsible for the mistletoe spread.
