What does zonation mean?
Zonation is the arrangement or distribution of something into recognizable zones, bands, or belts. In modern specialist writing, it most often describes ecology: how vegetation, animals, or communities are layered vertically on a slope or distributed across latitude, elevation, depth, or another environmental gradient. The word can also refer more generally to the act or pattern of dividing a space or system into zones, and specialists in fields such as geology may use it for belt-like distributions of materials. Unlike everyday zoning, which can refer to legal restrictions on land use, zonation focuses on the resulting spatial or structural pattern and is normally technical rather than conversational. It is useful because it names order in apparently varied systems: a forest may form distinct belts on a mountain, while organisms in a lake may occupy different depth zones. The term’s Latin- and Greek-based history also links it to the broader family of words meaning a girdle, belt, or encircling band.
nounZonation is the arrangement or distribution of something into distinct zones, bands, or belts. It is especially used for the layered or latitudinal distribution of organisms and communities in an ecosystem.
- The patterned distribution of organisms or communities into ecological zones, often along an environmental gradient such as altitude, latitude, or depth.
- The division or arrangement of an area, system, or material into distinct spatial or structural zones or bands.
"As the water deepens, the zonation of coral communities becomes increasingly distinct."
"As the water deepens, the zonation of coral communities becomes increasingly distinct."
"Core samples reveal a pronounced zonation of minerals through the rock."
The plural is grammatical but uncommon; the singular is normally preferred for the general process or pattern.
"The study compared the zonations found on opposite sides of the ridge."
A forest climbs a mountain in bands; zonation is the name for that vertical choreography.

Etymology of zonation
Zonation was formed in English from the zone word family, using the related form zonate and the suffix -ion. Zonate and the related words zonal and zonary belong to the family of zone, which entered English through French from Latin zona, a borrowing of Greek zōnē, meaning a girdle or belt. The development of zonation extended this idea of an encircling area to the arrangement or distribution of something in distinct zones.
How zonation is actually used
This is a technical and relatively uncommon word in general prose. In contemporary usage, it is especially associated with ecology, geography, oceanography, and geology; outside specialist contexts, words such as arrangement, distribution, or division may be clearer.
Easily confused with zonation
Zoning often denotes the regulation of permitted land uses, whereas zonation describes an observed or planned arrangement into zones and is especially common in scientific writing.
