Sažetak
The aim of this work is the analysis of marshland vegetation flora of the Phragmito-Magnocaricetea class in Croatia using proportions of chorological types (floral elements). Chorological types are divided in accordance with Horvatić and collaborators, published in 1967. The analysis was carried out on a data set of 40 communities, 680 relevés and 420 plant species. As a result, it was obtained that plants of Eurasiatic chorological type predominate, with a 36% share, followed by cosmopolites with 25%, Circumholoarctic chorological type with 12%, European plants with 9%, South-European-Mediterranean plants with 5%, and neophytes with 4%, while all other chorological types are represented with 9%. The results show that most species are distributed over large areas, and there is only a small number which are restricted to small areas. The proportions of floral elements reveal that marshland flora and vegetation are rather unified across large areas, which is a consequence of the medium of water as an equalizing ecological factor, and migratory birds which are connected with marshland habitats. Analysis of chorological types of marshland communities can also serve in nature protection. For example, the species Carex randalpina and appertaining community are distributed over a relatively small area of Central Europe, and with a small number of known localities, especially in Croatia, and therefore more attention should be paid to the preservation of such habitats.
