11 cm diameter dry pitfall traps are placed in the ground and left open for a week before counting the organisms. The organisms are identifiedon site to the best recognizable unit, and they are released soon after the count.

Night visual observations using UV torches, in moonless or first quarter moon nights. The observations are conducted by 2-3 observers, walking along three belt transects,20-30 minutes for each transect. The data is collected using ArcGIS Survey123 app.

Moths are observed by using light traps of the “Jalas” model that are equipped with 160W mixed light or 125W Mercury (Hg) vapour bulbs (Jalas, 1960; Söderman, 1994). Traps are run every night from the early spring to the late autumn, typically between April and October. Traps are usually emptied weekly and the moth specimens are identified

The aim of the yearly sampling of “Compositional Diversity Transects” (FH-CDT) at the Fülöpháza LTER site is to study the effects of weather on the spatial organization of open sand grasslands. Two open sand grassland patches have been sampled yearly from 2004 at the time of the phenological optimum of the communities. We collect data about the co-occurrence of vascular and non-vascular plant species in transects of contiguously arranged micro-quadrats. Transects are permanently marked. Plant presence is considered if there is an overlap between the aboveground part of a plant individual and the sampling unit (micro-quadrat). We sample 5 cm x 5 cm contiguous micro-quadrats arranged along 52 m long transects. One transect sampled in each patch. From the base-line data we estimate Compositional Diversity (i.e. diversity of species combinations), the number of realized species combinations, mean species richness and the spatial variance of species richness at three representative scales (5 cm x 5 cm; 5 cm x 25 cm; 5 cm x 200 cm) using computerized sampling.

Soil and water samples are collected every year during the summer in the RMO site and species composition was determined using DNA metabarcoding.
