Sažetak
The last comprehensive study of the genus Sphagnum in Croatia from 1928 was the basis for all newer species lists, but without any newer data. However, some new localities were discovered, but only the presence of unidentified peat mosses was stated. To gain recent data concerning diversity, distribution and habitat preferences of peat mosses in Croatia, new extensive field research has started in 2009. Up to now 23 species on 24 localities were found. In 1928 number of known species was 22, of which 20 was confirmed by recent research. Sphagnum warnstorfii can be treated as extinct due to habitat destruction and Sphagnum rubellum was most likely mistaken for Sph. capillifiolium. Three new species were found: Sph. teres, Sph. platyphyllum and Sph. tenellum. 19 of 27 localities from 1928 have disappeared, 13 among them were bogs. All together, in 1928, 18 bogs, 5 forest, and 4 meadow habitats were known. Thereafter 16 new localities have been discovered, resulting in 11 bogs, 11 forest habitats, 1 wet meadow and 1 habitat in karst field. It is quite certain that majority of those newly discovered localities existed in 1928. Therefore, it can be assumed that around 45% of peat moss sites in Croatia disappeared in last 84 years. Majority of those “old” localities have impoverished peat moss communities compared with the status in 1928. Although the number of Sphagnum species itself has been more or less unchanged during the last 84 years, habitat loss and impoverishing is enormous, making peat mosses one of the most threatened plant groups in Croatia.
