N. Potočić, I. Seletković: STANJE OŠTEĆENOSTI SUMA U REPUBLICI HRVATSKOJ 1998. GODINE Šumarski list br. I 2, CXXIV(2000), 51-56 oštećenost krošanja crnogorice znatno je porasla u odnosu na 1997. godinu zbog utvrđivanja prostorno-vremenskih trendova u oštećenosti krošanja monitoring će se nastaviti potrebno je utvrditi razloge većih odstupanja procijenjene oštećenosti pojedinih vrsta drveća u odnosu na prosjek oštećenosti za te vrste u Europi, osobito kod vrsta kod kojih je utvrđen isti trend .

In this paper the results of the 1998 assessment are shown. The crown condition data for our most important tree species is given separately, including the comparison with the results of European assessments. Based on the results of monitoring in the past years, the graphs were made showing the trends of crown damage in Croatia and Europe.
