Abstract

Dolomite outcrops are well known for their high ability to retain plant diversity. Due to isolation and reduced sizes, they often support small plant populations, which may be exposed to anthropic pressure due to tourism. We evaluated the botanical and ecological importance of the small isolated outcrop Csóka-kő and of the surrounding Kő-hát, located in the Keszthely Mountains. We grasped the concept of biodiversity by assessing its three different aspects: species richness, diversity of plant families and the number of protected species, and we evaluated the influence of climate on the geoelement composition. In a relatively short study period, we identified 188 vascular plant species across 141 genera and 55 families, of which several were red listed. Submediterranean geoelements were the third most frequent, indicating the expected influence of the Submediterranean climate in this region. Our findings signal outstanding floristic diversity and conservation value of Csóka-kő and its surroundings.
