We studied the non-forest vegetation of the Runina village, located in the Poloniny National Park (north-east Slovakia). We mapped 90 vegetation stands, recorded their structure and species composition. The species diversity, naturalness and nature conservation value of individual records were assessed. The mapped stands have a high degree of naturalness, a very small representation of non-native and invasive species was found. We found a significant number of threatened (34) and protected (20) taxa. Mountain meadows have the highest nature conservation value followed by wetland habitats in lower positions. The continuation of the extensive agricultural use of the landscape, sensitive management in wetland habitats and restoration of regular mowing of mountain meadows are the most important measures for maintenance of the high natural values of the studied area.
