17 Postojna Planina Cave System (SI)


eLTER TA site

  • Dominant ecosystem: Underground habitats, caves
  • Access: 1.5 km from Postojna. PPCS and related sites accessible all year round
  • DEIMS site code: LTER_EU_SI_002_001

Postojnska jama (Postojna cave) is a part of the Postojna-Planina cave system (PPCS), the most biologically diverse cave in the world. Postojnska jama is a cradle of speleobiology, a locus typical of the cave beetle Leptodirus hochenwarti, the first recognized cave adapted animal, and many other aquatic and terrestrial species. PPCS consists of 24.1 and 6.6 km of passages, respectively, connected by flooded corridors, and has more known species of stygobionts (obligate, permanent resident of aquatic subterranean habitats) than any other subterranean site in the world. Scientific focus: Interdisciplinary karstological research covering chemistry, hydrology, physics, geology, cave meteorology, ecology, zoology, and geomorphology. Studies address biodiversity and ecosystem functions, anthropogenic impacts, climate change and socio-economic impacts.
