This research was carried out on protected and grazing and driven to abandoned pastures with a story o f different uses in Karahisar village of Tekirdağ in 2011 and 2012 years. The measurements were taken on four line in each of four designated sampling areas on the pastures. In the study, In all three pastures, families of plant species, kind of longevity and peak properties of species, climax species characteristics, these species plant covered area and botanical composition participation rates with the similaritycoefficients among the pastures quality, grade of pastures was determined. 206different specieshave been identifiedin pastures. The most species have been found in these families as 59 of Poaceae, 55 o f Fabaceae, 22 of Asteraceaeve, 10 of Lamiaceae, 6 of Brassicaceaeve, 5 of Rosaceae, 4 of Apiaceae an d Caryophyllaceae and 41 of other families. On grazing, protected and driven to abandoned pastures species have been found in 149, 177 and 130, respectively. In the grazing pastures, 83 of 149 species areperennial, 7 ones are biennial, 59 are annual and 26 of 149 species are decreasing, 25 ones are increasingand 98 ones invaders species. In the protected pastures, 96 of 177 species are perennial, 5.5 ones are biennial, 75.5 are annual and 30.5 of 177 species are decreasing, 31 ones are increasing and 115.5 ones invaders species. In driven to abandoned pastures, 39.5 of 130 species are perennial, 14.5 ones are biennial, 73 are annual and 14 of 130 species are decreasing, 22.5 ones are increasing and 90.5 onesinvaders species. On grazing, protected and driven to abandoned pastures, plant cover percentages are have been found in 79.06%, 84.48% and 65.85%, respectively. Community similarity coefficients an d quality scores varied between 39.65% and 67.67 % and 37.65% - 53.27% as depending on the pasturesrespectively. According to the quality scores, on protected and grazing pastures were in good and healthy and driven to abandoned pastures were in middle and healthy. According to research results, it wasconcluded that some qualitative features of Thrace pastures have higher than our other regions of highe r pasture.
