Graph models of Natura 2000 sites in Sardinia. a Raw-distance graph. Edges link pairs of nodes with a geographical distance up to 30 Km between boundaries. The position of each node roughly corresponds to the coordinates of the site centroid. b Full single-species graph for Cervus elaphus corsicanus (species code 1367). Edges correspond to a subset of the edges in the raw-distance graph; each edge links pairs of nodes with the target species reported to be present in both
