5.4.2. Kontinentale Zwergstrauchheide (Sefistrauchheide)

Juniperion sabinae

Description

Phyonomy and Ecology (© Delarze & al. 2015)

Die kontinentale Zwergstrauchheide besteht aus einem dichten Teppich aus flachen Sefisträuchern (Juniperus sabinai). Sie werden von anderen immergrünen Trockenpflanzen begleitet wie der Bärentraube (Arctostaphyllos uva-ursi) oder dem Wacholder (Juniperus communis). Die Krautschicht ist relativ artenarm. Diese Zwergstrauchheide erscheint oft im Mosaik mit Steppenrasen und trockenen Föhrenwäldchen, meist an sonnigen Abhängen, wo trockene, kontinentale Verhältnisse herrschen. Ihre Temperaturansprüche sind sehr gering, man findet sie von der submontanen bis in die alpine Stufe (Vispertäler) hinauf. Sie besiedelt flachgründige Böden auf kalkreichen oder -armen Substraten. Der Boden ist ausgesprochen humus- und nährstoffarm.

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.
