Sažetak
Gentiana cruciata L. is widely distributed species in Europe and western part of Asia. In Croatia, it has not been considered endangered. According to the existing data, it was considered rare in Nature Park "Žumberak - Samoborsko gorje". For this reason, we put emphasize on its observation during our mapping of vegetation of Nature park. We observed 17 localities in altitudinal range from 290 to 868 meters, on moderately steep terrain (mean slope equal to seven degrees) on various aspects with southeast aspect being slightly more frequent. In addition to already mentioned ecological factors, using the GIS environment, we associated the corresponding NDVI values calculated from LANDSAT ETM+ satellite image to the Gentiana localities and determined zones of the Nature Park that satisfies ecological requirements of the species. According to the spatial distribution of observed localities, the species is widely distributed in the Nature Park. However, observed number of specimens was mostly small, that together with species relation to the Bromo-Plantaginetum mediae association, that is slowly disappearing as a result of the natural forestation, arise question of population viability and survival in the future. Dependence of the endangered butterfly Maculinea rebeli on Gentiana as the host plant for complete life cycle, additionally arise necessity of better knowledge of ecology and preservation of Gentiana cruciata in Nature Park "Žumberak - Samoborsko gorje".
