Introduction
The salt-marsh communities of the NVC were described in Volume 5 of British Plant Communities, first published in 2000, along with the other maritime communities (those of shingle strandline and sand-dunes and maritime cliffs) and vegetation of open habitats.
In total, 28 salt-marsh communities have been identified.
The salt-marsh communities consist of four separate subgroups:
- three eel-grass and tassel-weed communities of tidal flats, pools and ditches (SM1, SM2 and SM3)
- thirteen communities of the lower salt-marsh (SM4, SM5, SM6, SM7, SM8, SM9, SM10, SM11, SM12, SM13, SM14, SM15 and SM26)
- nine communities of the middle salt-marsh (SM16, SM17, SM18, SM19, SM20, SM21, SM22, SM23 and SM27)
- three communities of the upper salt-marsh (SM24, SM25 and SM28)

Famous quotes containing the word introduction:
“We used chamber-pots a good deal.... My mother ... loved to repeat: “When did the queen reign over China?” This whimsical and harmless scatological pun was my first introduction to the wonderful world of verbal transformations, and also a first perception that a joke need not be funny to give pleasure.”
—Angela Carter (1940–1992)
“Such is oftenest the young man’s introduction to the forest, and the most original part of himself. He goes thither at first as a hunter and fisher, until at last, if he has the seeds of a better life in him, he distinguishes his proper objects, as a poet or naturalist it may be, and leaves the gun and fish-pole behind. The mass of men are still and always young in this respect.”
—Henry David Thoreau (1817–1862)
“For the introduction of a new kind of music must be shunned as imperiling the whole state; since styles of music are never disturbed without affecting the most important political institutions.”
—Plato (c. 427–347 B.C.)
