Identification of basic ecological resources such as flora and vegetation is one of the most important activities in the protected areas. These researches have especial importance in the arid regions due to habitat sensibility. The large part of Iran possess arid and semiarid climate and coastline of Persian Gulf have noticeable importance. Mond as a protected area with 53000 ha is situated in S. W Bushehr. Mond is a conspicuous symbol of saline habitat of Persian Gulf and is a biological museum that represent diverse spectrum of habitat and plant species and have important ecological values. Totally 142 plant species from 114 genera and 46 families were determined in the area. Poaceae, Asteraceae and Chenopodiaceae have 23, 17 and 14 species and are the largest families in the area. In case of life form, therophytes have higher proportion which followed by phanerophytes and chamaephytes. Chorologically, 24.4% of plants have monoregional distribution, of which Saharo-Sindian plants have the highest proportion. The remained percent of plants are related to more than one phytogeographical region ofwhich Irano-Turanian-Saharo-Sindian plants have the highest proportions. Plant habitats are including: mangrove, riverside, wetland, sand dune, humid, island and abandoned. Tahmadon, Omolgorm and Nakhilo represent island habitats that have high ecological and conservational values.
