Blue-green network

An interconnected spatial system in which a blue network and green elements together provide complementary landscapes and connectivity required by organisms or ecological processes. Green elements may be adjacent to or spatially separated from blue elements; their inclusion in the network depends on relevant structural or functional connections rather than adjacency alone. For organisms requiring aquatic, riparian, and upland environments during different activities or stages of their life cycles, the blue-green network describes the larger landscape across which those requirements can be met.
