1) Reconstruction of semi-natural vegetation at LEGO factory area
Our goal is to create a mosaic of open sand oak forest and open and closed sand grasslands at factory area in Nyíregyháza. In our study we investigate the effectiveness of different seed introduction methods and tree planting techniques.
2) The effect of seed quality in grassland restoration
The aim of our study is to investigate the effect of seed quality on in situ establishment of restored dry grassland. We study the relationship between seed germination of native species, and their in situ establishment, and the effect of short-term seed storage on field survival. We also study how to determine planting boundaries for restoration purposes based on population fitness and genetic variability of selected species.
3) The bryophyte propagule bank and its comparison with ground floor assemblage in
Central European temperate mixed forests
Species richness, composition and cover of the bryophyte diaspore bank of temperate mixed forests in Őrség is compared with the ground-floor bryophyte assemblage. The most important environmental variables (tree species composition, stand structure, microclimate, light conditions, soil and litter properties, management history, landscape properties) are explored that potentially influence species composition and richness of the bryophyte diaspore bank.
