The novelties in Croatian bryology

Although Croatia is bryologically one of the best- known regions of former Yugoslavia, most of the data originates from the time of the Austro– Hungarian Monarchy, gathered during the 19th and early 20th century. Until recently, the state of knowledge of the bryophyte flora of Croatia was largely insufficient, mostly due to the lack of local bryologists. In the last eight years a great effort was done in order to collect and digitize all literature and herbarium archives containing bryophyte data from the territory of Croatia. This yielded a large dataset which was finally incorporated into the national Flora Croatia Database as a new Bryophyte Modul, interconnected with Herbarium Croaticum Virtual Herbarium Webpage. In total, 160 literature references in several languages dating from 1832 to recent times were digitized resulting in more than 25, 000 spatio-temporal records. After a decade of digitization focused solely on vascular plants, a comprehensive systematization, digitization and nomenclature updating of bryophyte collection in Herbarium Croaticum was performed. This revealed around 12, 000 specimens belonging to as many as 1177 taxa from 408 genera, originating from all continents and major archipelagos. A new updated catalogue of Croatian liverworts and hornworts, containing all relevant literature data and contemporary records, was published in 2021, while a checklist of mosses is in preparation. Intensified field surveys and inventories across the whole country revealed over 40 new national records in the last ten years. Special focus was put towards some endangered bryophyte habitats such as peatbogs and fens and macrophyte vegetation of rivers and lakes, the research into altitudinal patterns of bryophytes diversity, Mediterranean ephemeral bryophyte flora, as well as monitoring of invasive Campylopus introflexus (Hedw.) Brid. Consequently, data on national bryoflora have been constantly increasing, resulting in stepping beyond 800 taxa.
