We monitor fine-scale grassland dynamics in permanent plots in 16 grassland patches at an annual basis since 1999. Patches dominated by either Stipa borysthenica or Festuca vaginata were selected in 1999 in the Fülöpháza Sand Dunes, in the Kiskunság National Park. In each patch, we have one control plot and two plots that were experimentally disturbed (digging or cutting) in 1999. Percentage cover of all vascular species were visually estimated in each year. During the study period, several drought events occurred in the area (2000, 2003, 2012, 2013), which affected species dominance. Drought caused high mortality in both dominant species, but Stipa recovered faster after drought events and gained importance. Years with average or above-average precipitation favoured Festuca recovery.

Temperature and precipitation from the site Kralova hola for period 2015-2018. The automatic climatic station is located in the acid alpine grassland.

The aim of the dataset is studying the effect of land-use on the plant species richness of different dry habitats. The field site network consists of 16 sites, of 5 km 5 km each, representing all major land-use/land cover types characteristic to the region (agricultural land, abandoned agricultural land, tree plantation, semi-natural grassland, and forest) in varying proportions. The first survey was made between 2006-2008, the second between 2019- 2021.
