Remarks on the ecological network new functions The ecological network was born as a response to the processes of fragmentation, although over time it has been understood in different ways, depending on the features that are intended to favour, translated in turn into different operative consequences that often have little to do with the functions of a ecological network. Currently, the total functional aspects of the landmosaic elements emerge gradually in a decisive way with a direct dependence between ecosystem services and functionality of the ecosystem. Biodiversity, as an indicator of ecosystem functionality, becomes key to achieving goals of economic, social and ecological management. Consequently, an ecological network must maintain space for the evolution of the ecological system in which biodiversity must move forward independently without any hindrance and the weight of anthropogenic actions must be commensurate with high levels of autopoiesis system, functional to maintain the highest efficiency of ecosystem services. The structural elements of an ecological network may define ecosystems where it is distributed even Critical Natural Capital and which assume a role of invariant landscape, both in the form of landscape structure (structural invariant), both in terms of processes (functional invariant). The quality of the landscape may be associated thus safeguarding of those territories which have special goods and services also depend on welfare of man, and that must be recognized that function as real and tangible value for the territory. The Ecological Network offers so formidable an opportunity to produce useful actions aimed at increasing the quality of the landscape and to preserve the capital stock of natural resources including biodiversity. Finally it becomes a key instrument for addressing the changes on portions of renewable resources and not inhibiting the processes by maintaining, acquiring a structural value as territory programplan of ecological improvement for the integration of planning tools to help identify quality territorial standards. This program-plan must be functional to characterize the landscape in accordance with the provision of ecological goods and services (and not only) that the system produces.
