PLOT 5: the Krumholtz area at 2100m a.s.l.
We are in the transition zone between the kingdom of the larches and that of the high altitude meadows. Here the shrubs alternate with ever wider stretches of meadows, mixed with large boulders emerging from ancient landslides, now vegetated and stabilized. In this environment the climatic conditions are rigid to the point of deforming and contorting the few, daring larch trees that are ambassadors of the luxuriant larch forests of Alta Vallesinella. Shrubby and twisted species, such as the mountain pine, the rhododendron and high-altitude willows are the most suitable for these environments. It is the so-called twisted wood area (from the German Krumholtz).
Here find a home, just to name a few, species such as the water pipit (Anthus spinoleta) that nests in open areas of high altitude and then winters in the plains, the northern wheatear (Oenanthe oenanthe), the Alpine accentor (Prunella collaris) that nests in the Alps between 1800m and 3000m a.s.l. in the cracks of the outcropping rocks and the black redstart ((Phoenicurus ochruros) which, very eclectic, nests from the cities to the mountain areas.
Within the Plot there are two habitats that have become part of the “Natura Network 2000 ” due to their value and to their scarce distribution on community level. A network of areas recognized by the European Union as strategic for biodiversity conservation at a supra-national level.
4070: Thickets of Pinus mugo and Rhododendrum hirsutum (Mugo – Rhododendretum hirsuti)
6170: Alpine and subalpine calcareous grasslands
8120: Calcareous scree and mountain and alpine calcareous schist (Thlaspietea rotundifolii)
