Abstract: Association Camphorosmetum annuae was reported in the second half of 20th century from relatively large areas of south-western Slovakia. The community retreats in Slovakia nowadays due to conversion of saline soils to arable land. This work deals with recent distribution and condition of the community in Slovakia. Phytosociological relevés were sampled using the adapted Braun-Blanquet scale and classified by TWINSPAN software. The results showed that the community has still occurred only on three sites near the villages of Veľké Kosihy, Iža and Kamenín, covering total area not larger than 70 m2. However, typical Camphorosmetum annuae was found only in the Kamenínske slanisko Nature Reserve near the village of Kamenín where covered total area only 0.01-1 m2. All other recent localities with occurrence of Camphorosma annua represent only secondary and disturbed habitats on more or less degraded saline soils. The vegetation cover on these localities is usually close to Festucion pseudovinae communities. The results documented that Camphorosmetum annuae is fast vanishing plant association in Slovakia and its survival and conservation is probably impossible without human impact
