The "Conca di Fusine" site is large, covering an area of 3598 hectares and including some typical alpine landscapes of the northern Julian Alps. Its eastern and southern borders are limited by the boundaries with the Republic of Slovenia, while the western one follows the Val Romana incision. More articulated is its northern variable limit that follows the valley connecting Tarvisio to Ratece and that passes always upstream of the inhabited centres. There are therefore included some valleys that develop in a north-south direction, the entire basin of the Fusine lakes, as well as the mountain range culminating to the south with Monte Mangart and to the east with Ponza. From the hydrographic point of view, this site falls in the Slizza basin and thus in the great basin of the Danube river. Its substrates are predominantly carbonatic, although rather developed morainic deposits are also present, important for the conformation of the Ratece plain. The height ranges from about 830 meters along the northern edge of the site to 2676 meters of the Cima del Monte Mangart. The altitudinal excursion is therefore very wide, with subalpine and alpine mountain ecosystems. The presence of the two lakes, along with a small peat bog, enrich the Conca di Fusine with important hygrophilous systems and host some habitats of considerable naturalistic value.
