title: Rare shady chasmophytic habitat communities (8210) in Ukraine
abstract: Abstract The characteristics of shaded chasmophytic habitats on calcareous rocks in forest conditions are described, where the forest canopy primarily acts as a shading factor that determines microclimate, humidity and light levels. These communities can be found in deciduous forests of the Carpinion betuli , Fagion sylvaticae and Tilio-Acerion alliances, where they are confined to steep calcareous rock faces and cliffs. Syntaxonomically, these communities belong to the Polypodietea class ( Cten
