The biodiversity of plant and animal species
The Palù di Livenza, as well as a dwelling site of great value from the archaeological point of view, it is an area of great natural interest.
The Palù di Livenza, also called Palù della Santissima, takes its name from the marshy valley of the source of Livenza, on the south-eastern slopes of Mount Piancavallo. The marshes of the area, between the springs of the river and water meadows in the valley are home to many species of plants and animals.
The marsh of the sources of Livenza was formed in a structural natural depression , bounded to the east by the Col Longone , to the west by the slopes of Cansiglio and crossed to the north by gravels transported by Gorgazzo river. At the base of the mountain range Cansiglio / Cavallo, from which they are derived, are aligned on a range of 5 km he three perennial springs of Livenza river: Gorgazzo (north-west), Santissima (in the village of Polcenigo) and Molinetto (in the village of Caneva ). We have a pool of water with fluctuating heights since prehistoric times, that in the last two centuries was subjected to various reclamation and plumbing works (excavation of ditches, canals, draining, the construction of a canal that runs through Col Longone for the supply of a power plant) that partially altered the natural moist environment. Despite the introduction of these changes, we still have a stratified deposit of extraordinary importance for prehistoric archeology and for the study of environmental change over the past 15,000 years.
