Sažetak
The research of infection of silver fir (Abies alba Mill.) with mistletoe (Viscum album L. ssp. abietis (Wiesb.) Abrom.) was carried out in natural fir stands in Croatia. In the area of Gorski Kotar 32.8 % of the examined dominant trees were infected with mistletoe. The mistletoe incidence was presented according to the damage degrees of silver fir from 0 (healthy trees) to 4 (dead trees), rated by the crown defoliation and needle discoloration. With the increase of infection, mistletoe spreads more onto more vital, i.e. less damaged silver fir trees. In the Dinara Mountains region 28.6 % of the examined fir trees were infected, this percentage amounting to 27.1 % for the mountainous regions between the Sava and Drava rivers. The site and stand parameters (exposure, soil type, elevation, site quality, forest community and crown closure) were analysed in order to establish whether there was a correlation between these parameters and infection of silver fir with mistletoe. The correlation of silver fir mortality in 2004 and mistletoe incidence in 2002/03 was analysed, and their strong correlation was established. Mistletoe could be consider as a bioindicator of silver fir decline, and probably a significant contributor to that decline. In the areas where mistletoe incidence is great it can be presumed that silver fir is significantly damaged.
