Provincial nature reserve
This is undoubtedly one of the best known nature reserves, as its protection, recognised in 1974 by the municipality of Baselga di Piné, has become a model for these small protected areas.
It is a 'peaty-palustrine basin', in that it is an ancient lake that has been almost completely swamped and transformed into a marshland in which, however, there still remains a residual sheet of water of fair size, surrounded by a large reed bed.
The Reserve is also a Special Area of Conservation.
