Description
Phyonomy and Ecology (© Delarze & al. 2015)
Diese Einheit umfasst Lebensgemeinschaften mit frostempfindlichen Farnen und Moosen an überrieselten Kalkfelswänden, deren Mikroklima dank ihrer Lage, besonders im Winter, mild ist. Der Kalkniederschlag wird durch eine Vielzahl mikroskopischer Algen und die schnelle Erwärmung des Wassers beim Quellaustritt gefördert, wodurch Tuff und Travertin gebildet werden. Das Adiantion besetzt im Allgemeinen gut geschützte Standorte, häufig in Schluchten oder unter beschatteten Überhängen. Die Bestände sind kleinflächig und oft sehr weit voneinander entfernt.
Distribution map
- Calculation method
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.
