This study analysed a natural site located in Central Italy which is a part of the Circeo National Park. An integrated approach was developed to correlate Remote Sensing TM data with field measurements of leaf Area Index (LAI). Six vegetation types were discriminated by a supervised classification of the Circeo forest. Approximately 80% of the surface of the territory analysed is dominated by natural mixed oak woody communities. Pine reforested areas are also present, LAI field measurements were correlated with normalised difference vegetation index (NDVI) obtaining a high correlation (y=15.587x(2.2967); r(2)=0.88). An estimation of LAI for the entire forest was performed and an LAI map created. The correlation between the measured and the estimated LAI was also high (r(2)=0.91). The study shows the potential of spatial scale integration to analyse and to monitor plant coenosis in Mediterranean areas.

Abstract
This study analysed a natural site located in Central Italy which is a part of the Circeo National Park. An integrated approach was developed to correlate Remote Sensing TM data with field measurements of leaf Area Index (LAI). Six vegetation types were discriminated by a supervised classification of the Circeo forest. Approximately 80% of the surface of the territory analysed is dominated by natural mixed oak woody communities. Pine reforested areas are also present, LAI field measurements were correlated with normalised difference vegetation index (NDVI) obtaining a high correlation (y=15.587x(2.2967); r(2)=0.88). An estimation of LAI for the entire forest was performed and an LAI map created. The correlation between the measured and the estimated LAI was also high (r(2)=0.91). The study shows the potential of spatial scale integration to analyse and to monitor plant coenosis in Mediterranean areas.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
