Floristic diversity in silver fir – beech forest on Croatian karst explained with ecological and forest stand structural factors

Silver fir – beech forest represents almost continuous area of 3000 km2 making it the most widely distributed altimontane forest on Croatian karst. Its syntaxonomical status is still not completely resolved. To give further insight into its ecological and floristic characteristics, survey across complete areal was carried out. Sample consisted of 151 plots (cca. 500m2) with two smaller ones (cca. 80m2) positioned insight each of them, i.e. 302 small plots. Data about floristic composition of over 200 species, available light (measured with hemispherical photographs), stand structures (e.g. increment, crown damage, volume) and geographic coordinates were sampled in the field. In frame of the GIS, data about altitude, climatic variables, and DEM derived variables (e.g. slope, aspect) were sampled. Using multivariate analyses (cluster and ordination analyses) several distinct groups were identified based on their floristic profile, with most important ecological and forest stand structural factors recognized.
