In dieser Heidegesellschaft dominieren die immergrünen trockenheitzeigenden Zwergsträucher wie Juniperus communis ssp. nana, Arctostaphylos uva-ursi und Calluna vulgaris in Begleitung anderer Heidekrautgewächse. Juniperion nanae wächst auf sonnigen Felsabhängen der subalpinen und unteren alpinen Stufe in Regionen oder Geländeabschnitten, in denen ein kontinentales Mikroklima herrscht. Angepasst an Sommertrockenheit, müssen diese Pflanzen auch tiefe Wintertemperaturen (bis – 40 °C) aushalten, weil sie oft nicht von einer isolierenden Schneedecke geschützt sind. Der Boden ist sauer und nährstoffarm und eher flachgründig.
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. |
