Abstract

This paper presents the results of a phytosociological study conducted on the southeastern Adriatic islet of Proizd (0.632 km²). Based on 48 phytosociological relevés collected in 2024, following the Braun-Blanquet method, six plant associations, one subassociation, and one community, representing six alliances and classes, were identified. The benthic cormophyte community at depths of 1.5 to 15 meters is characterized by Posidonietum oceanicae. The halophytic vegetation of coastal low rocks is dominated by Plantagino holostei-Limonietum cancellati, with a new subassociation, helichrysetosum italici, proposed. Forest vegetation is represented by the Pistacio lentisci-Pinetum halepensis association, while the maquis is dominated by Pistacio lentisci-Juniperetum turbinatae. The garrigue is represented by the Erico-Rosmarinetum association and the Cistus monspeliensis community. The thermophilous late-summer weed vegetation on sandy soils is represented by the Portulacetum oleraceae association. Although historical vegetation plots for Erico-Rosmarinetum are limited, recent data do not indicate significant changes in biodiversity at the local community or individual species level.
