The ecological corridors allow protected species to migrate autonomously between the areas defined by the Natura 2000 project. Although corridors bring multiple advantages in theory, in practice their addition increases exponentially the complexity of managing the territory and monitoring the fauna. Through the use of the software suite exposed in this paper, it is possible to study the ecological corridor simply and effectively thanks to the classification and representation of the central and critical patches. The paper will focus on the structure and functioning of ECGraph, the software that deals with the logic needed to identify the crucial nodes of the corridor thanks to the theories of complex networks. Some considerations have also been added to the description of the software for its future refinement thanks to some metrics not yet implemented. Each step of its functioning will also be represented thanks to ECOverview, a graphic software designed and developed for a simpler representation of the results obtained by ECGraph.
