The CONA project focuses on the river basin of the Corno, which is also part of the river basin of the Idonzo and the nature conservation area of the Cona island, and discharges into the Adriatic sea. Everything planned for the basin will contribute to improve water quality and improve the preservation state of natural habitats and animal species. The action in the area of the municipality of Monfalcone is an important part of the project, as it will have a significant influence on the direct reduction of environmental pressure in the nature conservation area of Cona island.
