Abstract :

Determination of the Flora of natural areas and identification of plant species is the basis for environmental planning in any region and identification of the vegetation status. The aim of this study is to investigation of the flora and chorotype of plants in Alagol, Almagol and Ajigol wetlands in Golestan province. In order to study the region's flora, plant species were collected during the growing seasons of years 2015 to 2016 and were identified. In total, 105 species belong to 84 genera and 39 families were recognized. Asteraceae with 18 species, Chenopodiaceae with 18 species and Poaceae with 14 species were the largest families according to species number. Results of the life form spectrum indicates that therophytes (48.3%) and hemi-Cryptophytes (21.9%) were the most frequent life forms of the region. With regard to the geographic distribution, most of the species were belonged to pluriregional (20%) and Irano-Turanian (16.19%) elements. Comparison of wetlands based on life form indicates that therophytes are most dominant life form in all three wetlands; Hemi-cryptophytes are in the next order. Comparison between wetlands based on geographic distribution indicates that bi or tri-regional elements consists most of the flora in all three wetlands.
