Salt-marsh Communities in The British National Vegetation Classification System - Introduction

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)

    “The role of the stepmother is the most difficult of all, because you can’t ever just be. You’re constantly being tested—by the children, the neighbors, your husband, the relatives, old friends who knew the children’s parents in their first marriage, and by yourself.”
    —Anonymous Stepparent. Making It as a Stepparent, by Claire Berman, introduction (1980, repr. 1986)

    “For better or worse, stepparenting is self-conscious parenting. You’re damned if you do, and damned if you don’t.”
