Summary Under the perspective of forest ecosystem management, landscape is interpreted as a functioning structure. From an inventory and monitoring operational point of view, such an approach implies wise use of geographic information systems and remote sensing techniques enabling a global view of the territorial mosaic. From a methodological point of view, landscape ecology theory may be used as the assessment framework. Remotely sensed data provide excellent opportunities for the involved analyses, using both vegetation density measures and spatial statistics. The objective of this paper was to assess landscape spatial heterogeneity using an analysis method based on Shannon's information theoretic entropy applied to satellite remotely sensed inputs of plant biomass. A forested mountainous landscape of Central Italy was examined as a case study. In this area, anthropogenic disturbance resulted as opposing the natural tendency of vegetation towards an horizontally homogeneous landscape giving way to a mic...
