Along with a brief introduction to the four research articles of the Special Issue “Classification of Palaearctic grasslands”, we present a bibliometric analysis of publication trends regarding classification of Palaearctic grasslands in journals included in the Web of Science database. Regional studies (covering only a part of a country’s territory) prevailed (51%), but supra-national studies were more numerous (34%) than national overviews (15%). Four European countries (Austria, the Czech Republic, Italy and Slovakia) were included in the highest number of grassland classification studies (12 each). The publication of grassland classification studies in Web of Science journals continuously increased during the last 15 years. Festuco-Brometea and Molinio-Arrhenatheretea were the most frequently studied grassland classes. Phytocoenologia and Tuexenia were the most popular outlets for original grassland classification studies, while Journal of Vegetation Science had a leading position in publishing methodological articles with relation to grassland vegetation. Methods of unsupervised hierarchical classification were most common in grassland classification studies. Publications outside the Web of Science were not analysed although they represent an important source of knowledge in grassland classification.
