Field agriculture cannot be conducted in a large part of ground lands exposed to salinity in Igdir Plain, and the lands are benefited by grazing or reaping. Study was conducted with the aim of determining species composition of never before studied natural ground meadows affected by salinity at different levels and the differences between them, and providing a base for subsequent studies. Vegetation measurements in meadow zones with no salinity problems (EC=0.4 dS/m, DSY=4.3%), saline (EC=4.82 dS/m, DSY=11.6%), alkaline (EC=1.48 dS/m, DSY=39.1%), and saline-alkaline (EC=4.31 dS/m, DSY=39.7%) in the years of 2012-2013 were carried out with Quadrat method (0.5x0.5=0.25 m2) at the end of blossoming period of dominant species. Accordingly, 39 species from the meadow zone with no salinity problem, 41 species from that with salinity problem, 38 species from that with alkaline problem, and 26 from that with saline-alkaline problem were determined. As a result, it was found that species composition of meadow zones differed according to family in particular, that decreased the number of legume species in saline conditions, and that the number of species less preferred by animals increased.
