It represents the gradual transition between the coniferous wood and the alpine pasture. It is also called the “contorted shrubs” horizon due to the presence of woody species with prostrate and crawling habits.
A typical specie is the alpenrose, an evergreen shrub that grows on soils rich in humus, preferring  north facing slopes where it receives a prolonged protection under the snow cover.

Blueberries are also widespread, renowned for their edible berries, along with several species of lichens.
The dwarfed juniper is present on the more exposed slopes, a shrub that grows very close to large boulders and exploits the heat retained by the rock.
