Inland salt meadows are exclusively rare in Bulgaria. One of the most representative localities of this habitat in the country are the Inland salt meadows near the town of Radnevo. The object of this study is the inland salt meadow located north of the town of Radnevo near the village of Daskal Atanasovo between coordinates 42o19.60 and 42o 19.185 N, 25o53. 890 and 25o 54.506 E.It was developedonGleycVertisols, surface water logging, slightly saline soil. The aim of the study was to investigate the relationship between soil salinity and the vascular plants in the Inland salt meadows near the town of Radnevo. The survey was conducted in 2011-2012. A total of 60 soil samples were taken from a depth of 0-20 cm. In each sample taking point the vascular plants existing there were also collected. Electrical conductivitiy (EC) and pH of soils were analyzed. The relationship between soil EC values and the recorded 57 vascular plants was studied. A different saltiness level has been registered on the territory of the inland salt meadow. Four species - Taeniatherum caputmedusae (L.) Nevski, Trifolium repens L., Elymus elongatus (Host.) Runemark, Cynodon dactylon L. have been found at locations with varying saltiness level from weak to medium, and six species - Carex divisa Huds, Hordeum hystrix Roth, Alopecurus geniculatus L., Bromus commutatu Guss. ex Steuds, Carex distans Host. and Trifolium resupinatum L. have been found both on saline and non-saline soils. The dominating species on the studied territory have also been specified.
