Sažetak
Silver fir – beech forest is the most widely distributed altimontane forest on Croatian karst. Growing on almost 3000 km2 of very complex terrain structure it is exposed to various environmental conditions. To give further insight into its ecological and floristic characteristics, survey across complete areal was carried out. Sample consisted of 151 plots (cca. 500m2). Overall, 210 vascular plant species were identified, with number of species per plot ranged from 8 to 56 (i.e. 26 to 44 for plots between 10 and 90 percentile). For 80% of surveyed plots altitude were in range from 700 to 1200 meters, slope from 10 to 28 degrees, while southern and western slopes were slightly more frequent than northern and eastern ones. For all plots data about climate were averaged for the period 1956-1995 on monthly bases. Based on cluster analyses of climatic data, three distinct groups were identified: Gorski Kotar, northern and southern Lika. Plots from southern Lika tend to be quantitatively poorer with present plants (8 to 40). However, grouping of plots based on floristic assemblage didn't follow macroclimatic pattern. It was more similar to that obtained with analyses of terrain features (altitude, slope, aspect) that represent indirect microclimatic variables.
