The Species Composition on Agricultural Terraces in NW Part of Slovakia

Abstract

The article contributes to a deeper understanding of agricultural terraces in NW Slovakia. The agricultural terraces found in 12 mountain ranges were characterised in detail on 32 localities. The slope parts of the studied terraces are on average only 2.3 m wide and current and former agricultural areas between them are on average 11 m wide. Furthermore, seventy phytosociological relevés were made on the terraces. Overall, 360 species of vascular plants were found in the relevés, 66 of which appeared regularly The localities were evaluated by DCA analysis. The main factor infuencing the species composition appears to be the geological composition of the bedrock and, probably the altitude as well. High coverage of the herb layer (median value 95%), low coverage of the shrub layer (median value 5%) and the absence or a very low coverage of the tree layer is typical for these terraces.
