Sažetak
The «Žumberak – Samoborsko gorje» Nature Park is situated in the western part of Central Croatia. Its biggest part consists of the Žumberak hills, a geographycally compact mountain massive which also encompasses the Samobor hills. During the vegetation period of 2002 and 2003 the research was conducted in the Park area in order to establish the number, distribution, and the state of endangerment for certain plant species and their habitats as accurately as possible. The research included habitats where these species were supposed to grow due to their very specific characteristics. The presence of plants was recorded, most of them were photographed, and only some of them were collected as a reference material. Vegetation records were made for documenting the present state of vulnerable habitats and estimation of endangerment. Some of the records were compared with the existing ones, made a few years ago. The habitat endangerment was estimated on the basis of the qualitative and quantitative changes in the floristic composition. We recorded the considerable amount of plant taxa which are listed in the Red Book of plant species of the Republic of Croatia, as well as 5 endemic taxa and 17 taxa protected by Law. We also made a list of rare species of this area: Iris croatica, Equisetum hyemale, Paeonia mascula, Ranunculus cassubicus, Polygala chamaebuxsus, Daphne cneorum, Daphne blagayana etc. Many natural habitats were established in the Park which are still not endangered. Some of them are worth protecting because of the important or unique floristic composition. Only wet and swampy habitats near human settlements and habitats on which medicinal plants grow are endangered by the negative anthropogenic influence. The most endangered habitats in the Park are especially the anthropogenic habitats: different types of grasslands are endangered by the lack of human activities, which is a consequence of depopulation and abandonment of traditional rural way of life. These habitats will eventually disappear in the natural process of succession, which will result in losing many species, and in decline of floristic diversity of this area.
