Natural community succession, moving targets due to an environmental pressure. E. g. in water absence a community may drift or migrate to adapt to the ecological pressure. Core areas of habitat where special environmental circumstances have enabled a species to survive after extinction in surrounding areas. Critical for strategic, long term planning of protected areas.
