The occurrence of bands of characteristic vegetation in an area. Examples include the bands of different types of seaweed that occur progressively up a shore from the low-tide to the high-tide levels. Species from the low-tide zone would dry out and die at the high-tide level, whereas high-tide species could not withstand prolonged immersion in seawater in the low-tide zone. The varying vegetation in turns attracts varying animal species.
