Phytosociological database of non-forest vegetation of Croatia

Phytosociological research of vegetation in accordance with the Braun-Blanquet methodology has been carried out in Croatia for about 80 years. The foundations of vegetation science were established by Ivo Horvat and Stjepan Horvatić, followed by many botanists, resulting in numerous phytosociological publications. A phytosociological database of non-forest vegetation of Croatia has been in construction for several years. The programme TURBOVEG is used for the input and storage of data. So far, 5610 relevés and more than 135, 000 records of plant species-locality have been collected. Various attributes are associated with each relevé, some of the most basic being: literature source, date of sampling, locality, coordinates, relevé area, exposition, inclination, vegetation cover, name of community, type of management. Best covered by the data are grassland, water, marshland and halophilous vegetation. For these types of vegetation almost all available relevés have been collected, while the database of ruderal, weed and other types of non-forest vegetation is still in preparation. The grassland vegetation of Croatia shows great biological diversity. As of now, about 110 associations of grassland vegetation are known, and a total of 3350 relevés have been entered into the database. The best-represented communities are of the Molinio-Arrhenatheretea class. The most widespread association is Arrhenatheretum elatioris, in broad terms. Water and marshland vegetation are represented by 1040 relevés. Most of the data belongs to the Phragmito-Magnocaricetea class, and the most frequent marshland association is Phragmitetum australis. The database of the halophilous coastal vegetation of Croatia embraces 510 relevés. The most widespread is the vegetation of maritime rocks that belongs to the association Plantagini-Limonietum cancellati. In the database, other types of non-forest vegetation are represented by 710 relevés. Since the vegetation syntaxonomic system in Croatia is neither unified nor processed by numerical methods, the current database will serve for further phytosociological investigations, various ecological analyses, as a basis for protection actions, and for many other aspects of vegetation research.
