The system used to describe fringing coral reefs. These reefs are commonly have six distinct areas (or zones): shore, back reef, flat reef, reef crest, fore reef and drop-off. (From the Beautiful Oceans on-line course.)
The presence of organisms within a particular range, as in the vertical zonation observed in the intertidal.

distribution of plants or animals arranged in zones or bands, caused by gradations of abiotic and/or biotic factors.
Distinct plant and animal associations; recognisable as horizontal bands along the seashore that divide the habitats.
The distribution of plants and animals into different geographic zones
