Megjegyzések:	In the course of the diversity studies carried out in 28 quadrant of five different habitat types (swamp, fresh grasslands, dry grasslands, bushes and woodlands) in the spring and early summer aspects of woodlands and grasslands in the Nyírség 226 plant species were identified in total. Following this, the social behaviour types, naturalness values and four ecological indicator values of all plant species were collected into tables. Most diverse and most complicated structured habitats are the open sandy oak woodlands with grassland mosaics and the closed sandy oak woodlands (29 species). At the same time habitats poorest in species were also found among woodlands: planted northern red oak with three species High number of species characterises natural open and closed sandy grasslands (25-27 species) and one studied site of fresh wet grasslands (24 species) as well. In the rest of the areas diversity was less with species number less than 20 and even less than 10 in the case of swamps. Analysing the social behaviour types of species and the naturalness values calculated from them it was revealed that not the most diverse habitats are the most valuable. They are the moderately diverse bushes (willow and birch marshes) and the least diverse swamps where the ratio of unique specialists, rare specialists, specialists and competitors is high.
