corridor: a standalone construct

In conservation ecology a corridor is a strip of suitable habitat that connects two or more larger patches of habitat that would otherwise be isolated, so that plants and animals can move between them, recolonise empty ground, and keep breeding across the whole area rather than in separate pockets. Beier and Noss's 1998 review Do Habitat Corridors Provide Connectivity? weighed the field evidence and found that corridors often seem to help but that their benefit is hard to prove and remains contested. Here the corridor is a piece of living landscape measured in metres of width and kilometres of length, and it has nothing to do with a bundle of roads and rail between cities or a strip of territory that gives a country a route to the sea.[1]
