Evaluating and mapping naturalness of agricultural areas. A case study in central Italy

An assessment of the natural value of some extensively managed agroecosystems in Latium region (central Italy) has been made, through the collection of floristic and phytosociological data and the development of new indices (Floristic Naturalness Index – FNI and a set of synthetic indices). The survey allowed the evaluation of the study areas as High Natural Value Farmland areas. In a GIS environment, a mapping of the naturalness levels was then carried out.
