Naturbase is the Norwegian Environment Agency's database of protected areas (nature reserves, national parks, natural monuments and more) and habitat types mapped under DN handbook 13.

Used in environmental assessments, land-use and development cases, and as a nature/land signal in the Living Business Record.
