Description
The surrounding area, which is rich in streams, consists of wet meadow shelves into which the spruce (Picea excelsa) is gradually entering, causing the area to become closed as a result of the formation of the forest.
The biotope consists of a flat depression in which a peat bog has formed with elements typical of both lowland and transitional peat bogs.
In a first zone, the vegetation, established near a resurgence, consists of a stand on silty pools made up of infrequent entities such as Carex limosa or decidedly rare ones such as Scheuchzeria palustris.
Alongside these species of the low fens, there are characteristic accumulations of sphagnum mosses on which species typical of high fens such as the rare Carex pauciflora and Vaccinium microcarpum and the more common Vaccinium uliginosum and Vaccinium vitis-idaea appear. Elsewhere, Carex rostrata, a species with a broader ecology and linked to the presence of free water, predominates, while the uncommon Trichopohorum alpinum is abundant on sphagnum.
Adding to the biotope's value is the insectivorous plant Drosera intermedia, present forming a dense carpet over almost the entire surface.
Among the tree species that colonise part of the peat bog, in addition to spruce, there are a few rare stone pines (Pinus cembra ), which have descended from higher altitudes.
The neighbouring wet meadows are also of great naturalistic importance.
