Diese Schuttfluren kommen auf mächtigen Kalkgeröllhalden der alpinen Stufe vor. Ihr Deckungsgrad ist immer gering, und sie sind leicht zu übersehen. Die meisten Pflanzenarten dieses Lebensraumes sind an das «rutschende» Substrat der instabilen Schutthalden eng angepasst. Ihre lang gezogenen und geschmeidigen unterirdischen Organe finden nach Verschüttungen während der schlechten Jahreszeit immer wieder an die Oberfläche. Es gibt aber auch relativ unbewegliche («ruhende») Kalkschuttfluren des Thlaspion (Leontodontetum montani).
Current distribution: Weighted sum (number of characteristic and frequent species) per hectare based on current observations. Reported characteristic species are given a weighting of 10, while others are counted without weighting. The habitat is considered to be present in a grid cell (5 x 5 km) if it contains at least one hectare with a minimum value of 11 points. Potential distribution: Weighted sum (number of characteristic and frequent species) per hectare based on species distribution models. The calculation strategy is the same as for current distribution, but maps derived from species distribution models are used instead of current observations. |
