In ecology: zonation defines recognizable bands or groupings of plant and animal communities in certain environments, such as within salt marshes and along rocky shorelines[1]

In coastal zone management buffer zones ate established for coastal protection.

Marie McMahon has borrowed the word to describe an aesthetic zonation in which the elements repeat the patterns of zonation found in the intertidal zone and splash zone – and in concentrations of bracket fungus in the bush. Zones, bands and patterns belong equally to the domain of the artificial.
