upland karst habitats

The species gathered in this part of the botanical garden are representative of the part of the Karst furthest from the sea as well as the highest land where the cool climate and greater rainfall allow the development of beechwoods (Fagus sylvatica). These conditions of coolness and moisture have been recreated within the garden, along the southern  (north-facing) side of the doline using a system of interconnecting channels and basins. Evaporation from below causes a cooling of the upper layers of the soil allowing species such as Hairy Alpenrose (Rhododendron hirsutum), Dwarf Alpenrose (Rhodotamnus chamaecistus), Mountain Avens (Dryas octopetala), and endemics such as the Carniolan Primrose (Primula carniolica) and Scopolia (Scopolia carniolica) to exist away from their normal habitats.
