Provincial nature reserve - Biotope not established

The peat bogs that characterise the biotope can be divided into two groups according to floristic types.
The larger ones (4-5 hectares of surface area) are characterised by the predominance of vegetation peculiar to low peat bogs, with Cariceto (Carex spp.) and Trichoporum caespitosum (Trichoporum caespitosum), while the smaller ones (5000-9000 m2) are occupied by vegetation more typical of high peat bogs, with abundant mounds of sphagnum (Sphagnum spp.), and with the typical species that are able to colonise them.

The biotope is included in the Adamello Brenta Natural Park territory.

Description

In general, all wetlands are characterised by a wide variety of species.
Among the species in the raised bogs, established on the sphagnum mounds, Drosera rotundifolia, Drosera anglica (in large numbers), Vaccinium oxycoccus, Vaccinium vitis-idaea, Calluna vulgaris, Potentilla palustris were found.
The arboreal vegetation, spruce (Picea excelsa) and larch (Larix decidua), and shrub vegetation, juniper (Juniperus communis), rhododendron (Rhododendron ferrugineum), green alder (Alnus viridis), tend to colonise the peat bogs, distributing themselves mainly in groups in the areas with less water.

From a faunistic point of view, it can be seen that these peat bogs, so rich in brooks and rivulets that furrow them forming loops with stagnant water, are a very important feeding and breeding area for amphibians. In fact, a great diffusion of the mountain frog (Rana temporaria), both adults and larvae (tadpoles), has been found.

The strip of woodland immediately surrounding the peat bogs represents an ecotone, i.e. an intermediate environment between the wetlands and the forest environment, where the flora and fauna are particularly rich; in fact, the animal and plant populations of the two environments interpenetrate.

The biotope performs an important function for the macrofauna and ornithofauna of the surrounding woods, as it is a feeding and refuge place for Ungulates, such as the roe deer (Capreolus capreolus), and Tetraonidae, such as the capercaillie (Tetrao urogallus) and black grouse (Tetrao tetrix).
