Variable General Info
Naturalness vegetation index ?Comment:The Naturalness Vegetation Index (IVN) is derived from the Index of Landscape Conservation (Pizzolotto and Brandmayr 1996) and gives some concise information on the landscape conservation level based on the vegetation classification into degrees of naturalness and of area (%), occupied by each land-cover class (Ferrari 2001, Ferrari et al. 2008). A value close to 1 denotes a high naturalness of the landscape; lower values denote a landscape with a high level of anthropization. |
