littoral zone
Let an agent explain the littoral zone and its subdivisions, relay ecology, physical processes and regional forms from marine and freshwater science sources, describe management and threats, and distinguish the littoral zone from the sublittoral, pelagic and terrestrial zones and from legal definitions of the coast.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain the littoral zone and its subdivisions, relay ecology, physical processes and regional forms from marine and freshwater science sources, describe management and threats, and distinguish the littoral zone from the sublittoral, pelagic and terrestrial zones and from legal definitions of the coast.
The part of a sea, lake or river close to the shore, in marine ecology the zone between the high and low water marks and its adjacent fringes, including the wrack zone where seaweed and debris are deposited, the vegetated phytolittoral of lakes, and coastal grassland such as the machair of Scotland and Ireland formed on shell sand behind beaches; the littoral zone is highly productive, tidally stressed and a focus of coastal ecology and management.
What it is for: Not applicable; a coastal zone.
It can be explain subdivisions; relay ecology and processes; describe management; distinguish related zones.
Distinguishing features
Tidal influence
High productivity
Marine and freshwater forms
Regional habitats
What it looks like
The shore between tides, with rock pools, sand, seaweed lines and dune grassland behind.
Physical character
subdivisions: supralittoral, intertidal, infralittoral list - marine
machair extent: about 25000 hectares - Scotland and Ireland
lake littoral: photic zone near shore note
How it is recognised
Nearshore zone around the tide marks
Intertidal, wrack zone, phytolittoral, machair
The sublittoral is always submerged; the pelagic is open water; legal coastlines follow statutes

What the second pass must settle
- Should intertidal zone, machair and wrack zone be separate primary entries?
- How should marine science sources be linked?
- The registry entry has merged aliases naming distinct habitats; should they be split off?
