an aggregate of landforms, together with its biological communities, often comprised of a mosaic of varying land uses. (Source: DRobinson). [ALSO] A heterogeneous land area composed of a cluster of interacting ecosystems that is repeated in similar form throughout. The concept differs from the traditional ecosystem concept in focusing on groups of ecosystems and the interactions among them. Although rarely less than a few kilometers in scale, landscape is not necessarily defined by its size; rather, it is defined by the interacting processes relevant to the phenomenon under consideration (at any scale) (see “ecoregion” – these terms are often interchangeable). (Source: SMurray)
