The Marshland Vegetation (Phragmito-Magnocaricetea, Isoëto-Nanojuncetea) and Hydrology in the Hutovo Blato Natural Park (Neretva River Delta, Bosnia and Herzegovina)

The natural park of Hutovo Blato, Bosnia and Herzegovina, is one of the most important parts of the upper reaches of the Neretva River delta. In total, 11 plant communities of Phragmito-Magnocaricetea, and three plant communities of Isoëto-Nanojuncetea were noted, based on 64 phytocoenological relevés. Of all the associations of the Phragmition alliance, the stands of the Scirpetum lacustris colonize the areas with deepest waters - 0.5-1 m. The association Phalaridetum arundinaceae develops on the dryest habitats on the external margins and in terrain depressions along the Krupa River. The communities of the Isoëto-Nanojuncetea class represent annual pioneer vegetation on soils with temporary flooding in the period from autumn to early spring. Regulation of the Neretva River waters, where a few hydropower plants have been built in the upper reaches, can have an impact on the vegetation growth and distribution in the wetland. Among other factors, the survival of vegetation will depend greatly on the water level in the wetland that has decreased over recent years, owing to the general change in the hydrological regime. The final outcome will be the destruction of habitats.
