        Anzali Wetland is one of the 10 most valuable and international wetlands in the world. this wetland With an area of about 20,000 hectares is a habitat for a wide range of mammals, fish, birds, reptiles and, rodents. The study of plants species provides one of the required criteria for distinguishing a wetland area and is used in the process of ecological demarcation of the wetland. The vegetation in the water body and it’s around was studied by 42 sampling plots and its species were identified. 180 species belonging to 124 genera and 48 families were identified. The Poaceae, Asteraceae, Cyperaceae, Fabaceae, Brassicaceae and, Caryophyllaceae were the most abundant families, respectively. Classification of plants based on biological form showed that the highest biological form was related to therophytes with 43%. After that, hemicryptophytes with 18% and, geophytes with 16% had the highest ferequency, respectively. The plants in terms of geographical distribution, mainly belong to the cosmopolitan elements. 35% of species belonged to the obligate. The facultative upland with 32%, facultative wetland with 15%, facultative with 14% and Upland with 4% consisted other wetland indicator plants, respectively. Manuscript profile

        2 - Paleoflora and Paleoclimate of Norian (Late Triassic) in Iran
        JAVAD SAADATNEJAD
        Rock beds containing plant macrofossils of Norian in Alborz region belong to two stratigraphic units of Lalehband and Shahmirzad. The same beds in Kopeh-Dagh area belong to Mian-Kuhi Formation and in Central Iran belong to Qadir submember in Tabas region and Dehroud mem More
        Rock beds containing plant macrofossils of Norian in Alborz region belong to two stratigraphic units of Lalehband and Shahmirzad. The same beds in Kopeh-Dagh area belong to Mian-Kuhi Formation and in Central Iran belong to Qadir submember in Tabas region and Dehroud member in Kerman region. In general, plant diversity and vegetative cover during the Norian stage is less than Rhaetian especially Jurassic (Shemshak group) and the highest plant diversity of Norian in the Alborz basin is related to the phyllum of Pteridospermophytes (seed ferns) and in the Central Iran basin is related to the phyllum of Pteridophyta (ferns) indicating the higher humidity of the mentioned time in Central Iran basin and the drier climate in Alborz basin. The highest diversity of vegetation in Norian sediments throughout Iran belongs to the seed ferns (Pteridospermophyta) and the lowest diversity belongs to Ginkgophytes so that they comprise 32% (one third of the vegetation) and 6.5% of the total vegetation, respectively. Plant-covered areas throughout Alborz were interconnected during the Norian period and there was no extensive separation between them. The plant macrofossils assemblage in both Alborz and Central Iran basins confirms the relatively humid subtropical to tropical climate for the Norian but less humidity compared to the Rhaetian. Also, the vegetation of Norian in Alborz was less dense and scattered than Central Iran during Norian. Manuscript profile
