Sažetak
Carniolan lily (Lilium carniolicum Bernh. ex Koch) is a perennial herbaceous plant from the Liliaceae family, growing on the meadows and edges of forests and mountainous areas of the eastern alps: from Italy to Bosnia. Because of its beauty habitus and flowers it is often threatened and has been protected in Slovenia since 1947. In the Flora Croatica Red Book it is managed in the category of vunerable (VU) plants. Due to its great potential of Carniolan lily, the aim was to make a model of potential distribution with regard to ecological factors in Croatia. The field research was the mountain regions of Croatia and the model was done by the method of maximum entropy which proved to be reliable compared to other ecological modeling methods. The data of the distribution of Carniolan lily are taken from the Flora Croatica Database (FCD), while climatic layers in the form of raster are used from WorldClim databases, which are aligned to the same resolution, size and WGS86 (World Geodetic System) coordinate reference system (CRS). The model is based on 12 climate variables that are shown in raster form with pixel values at a resolution of 1x1 km. Each pixel point of the species is associated with the pixel value of each climatic variable. The results show that the variable Bio18 (percipitation of warmest quarter) has statistically significant influence on habitat suitability of Carniolan lily with 32.2%.
