Description
Its genesis, like that of many other wetlands in the Cembra Valley, is linked to the moraine blanket that covers the bottom of the depression in which it lies. The morainic material has favoured the slowing down of the small streams and springs that flow into it, thus leading to the formation of a small lake that has progressively swamped, transforming itself into the present peat bog.
As far as vegetation aspects are concerned, some research has made it possible to make interesting assessments of the dynamics of the vegetation.
Over a period of more than 60 years, the peat bog has undergone a profound evolution that has led to the progressive silting up of some ponds that were once present in the area. This occurred mainly due to the invasion by the marsh reed (Phragmites australis), which now occupies the entire surface of the peat bog with the exception of marginal areas acquired by the meadow.
The decrease in free water spaces has led to the disappearance or rarefaction of those plants that vegetate in the areas most closely connected to the water, while other plants characteristic of peat areas have expanded. The stand of black alders (Alnus glutinosa) is also more luxuriant today than it once was.
The biotope is also of considerable scientific interest with regard to the fauna population.
The invertebrate species, in particular, are numerous and some of them are rare for Italy. One of the species of Hydroadephagidae (aquatic beetles) found here, Agabus lagabrunensis, was even given the name of the peat bog, where most of the specimens collected by the scientists came from. For several invertebrate species, therefore, the Lagabrun peat bog represents one of the few provincial or even national stations where they still survive.
The biotope also constitutes an optimal environment for numerous species of vertebrates associated with both the marsh vegetation and the surrounding hay meadows and forests.
