With this editorial, we introduce the Special Collection “Classification of grasslands and other open vegetation types in the Palaearctic”. In searching the Web of Science for classification papers on Palaearctic grasslands, we found 207 studies from 1972–2021, including 106 typical classification works. These studies originated mainly from Europe, with only few from Asia and only one from Northern Africa. While Europe in the 20th century already had a strong tradition in regional classification studies, the launch of a common plot database (European Vegetation Archive, EVA) and a continental syntaxonomic reference list (EuroVegChecklist) have spurred the developments there in recent years. We then introduce the seven articles of the Special Collection. Four of them present regional studies of certain vegetation types, namely spring vegetation (Montio-Cardaminetea) in Grisons, Switzerland, dry grasslands (Festuco-Brometea) of the inneralpine valleys of Austria, montane to subalpine tall-herb vegetation (Mulgedio-Aconitetea) in the Sudetes Mts., Poland, and steppe depressions (Festuco-Brometea and Molinio-Arrhentatheretea) in Southern Ukraine. A new synthesis of the grassland vegetation of Navarre in Spain (all classes, focus on Festuco-Brometea), started with an unsupervised classification and translated it into a hierarchical expert system, while another study provided the first synthesis of the tall-herb vegetation (mainly Ulopteretea prangae) of Tajikistan. Finally, a study based on the GrassPlot database compared fine-grain beta-diversities across open vegetation types of the Palaearctic.
