“…In this dry, semi-arid zone, the distinction between tall-forb vegetation dominated by Apiaceae and the scree vegetation, which can also be dominated by species of Ferula, Prangos or Tetrataenium, is not clear (Nowak et al 2020a). Despite physiognomic similarities, the vegetation with the domination of Apiaceae species can be significantly different in species composition, abundance and habitat preferences.…”

“…However, towards the south such hygrophilous vegetation gradually gives way to the more thermophilous and drought-tolerant tallforb communities of the Irano-Turanian region. Middle Asia, as in the case of chasmophytic, steppe and forest vegetation (Nowak et al 2017a(Nowak et al , 2018(Nowak et al , 2020a, stretches on the borderland of these different, although closely related, types of vegetation. Distinct communities are formed here, particularly in the relatively moist and nutrient rich habitats of the Afghano-Turanian subregion sensu Kamelin (2010).…”

Aims: To complete the syntaxonomic scheme for tall-forb vegetation of the montane and alpine belts in the Pamir-Alai and western Tian Shan Mountains in Tajikistan and Kyrgyzstan with some remarks on its environmental predictors. Study area: Middle Asia: Tajikistan and Kyrgyzstan. Methods: A total of 244 relevés were sampled in 2013–2019 using the seven-degree cover-abundance scale of the Braun-Blanquet approach. These were classified with a modified TWINSPAN algorithm with pseudospecies cut-levels 0%, 5% and 25%, and total inertia as a measure of cluster heterogeneity. Diagnostic species were identified using the phi coefficient as a fidelity measure. NMDS was used to explore the relationships between the distinguished groups. Results: Our classification revealed 19 clusters of tall-forb vegetation in Middle Asia. Among others we found forb communities typical for Tian Shan, western Pamir-Alai, forb-scree vegetation of Pamir-Alai, dry tall-forbs and typical forbs of the alpine belt. A total of eight new tall-forb associations and five communities were distinguished. The forb vegetation of Middle Asia has been assigned to the class Prangetea ulopterae Klein. The main factors differentiating the species composition of the researched vegetation are elevation, mean annual temperature, sum of annual precipitation and inclination of the slope. Conclusions: The paper presents the first insight into the comprehensive classification of the alpine forb vegetation in Middle Asia and fosters progress in explaining the relationship of boreo-temperate and Mediterranean-like (Irano-Turanian) vegetation in western Asian and central Asian subregions of the Irano-Turanian phytogeographical region. Taxonomic references: The nomenclature of the vascular plants follows generally Cherepanov (1995) and for Bromus spp. The Plant List (2020) Version 1.1. http://www.theplantlist.org/. Syntaxonomic references: The names of syntaxa are used in accordance with Ermakov (2012), Gadghiev et al. (2002) and Nowak et al. (2018). Abbreviation: NMDS = Non-metric Multidimensional Scaling.

Tulipa L. (Liliaceae) comprises approximately 150 species. Although Central Asia, the main center of its diversity, includes around 66 species, detailed mapping of their distribution is limited and research on their ecoregional and phytogeographical dispersion is insufficient. This study aimed to map and analyze the distribution patterns of Tulipa across the Central Asian ecoregions and phytogeographical regions to identify potential hotspots for effective conservation efforts. The results identified the Gissaro-Alai open woodlands ecoregion, which hosts 41 species of Tulipa, as the leading hotspot ecoregion. The Ferghana Valley phytogeographical district (Afghano-Turkestan province) was found to be the most suitable habitat for 25 species of Tulipa. We also determined that altitude has a strong influence on the diversity of Tulipa and indicating increase of species richness as elevation rises. However, as elevation rises up from ca. 2000 m a.s.l. species richness also decreases slightly. An analysis of the distribution of sections of Tulipa in Central Asia revealed that around 61% of all species dwell in this area and that the sections Kolpakowskianae and Biflores, which have their greatest diversity of species, are specific to this area. The findings provide valuable insights into the distribution of Tulipa and allow for feasible recommendations and suggestions for their conservation.

“…This tall-forb vegetation is extensively grazed by sheep and, sporadically, goats. Ranges (Nowak et al 2020a). Occasionally, it occurs in forest openings and alpine meadows, but forms the com-munity in the valley bottoms, particularly often in sites with coarse blocks of rocks from eroded rock walls (Figure 6a).…”
