Enumerants (presented in a natural order)
Status Attribute label Enumerant label ▾ Concept definition Code Ref type Reference Supplemental references
STD
2005/06/07		 WETLAND_SURFACE_FORM SLOPE_BOG A <BOG> occurring in areas of high rainfall on appreciably sloping land <SURFACE>s. The <BOG> is fed by rainwater and by water draining from other nutrient-poor peat lands. The peat may exceed 1 metre in <<THICKNESS>>. 16 IR [ECORC, Wetland Surface Forms, B18]  
STD
2005/06/07		 WETLAND_SURFACE_FORM SLOPE_FEN A fen occurring mainly on slow-draining, nutrient-enriched seepage slopes; slope fen. Pools are usually absent, but wet seepage tracks may occur. Peat <<THICKNESS>> is usually less than 2 metres deep. 17 IR [ECORC, Wetland Surface Forms, F11]  
STD
2005/06/07		 WETLAND_SURFACE_FORM STREAM_MARSH A <MARSH> occupying <SHORELINE>s, <SAND_BAR>s, stream beds, or <ISLAND>s in continuously flowing <WATERCOURSE>s, and which is subject to prolonged annual flooding; stream marsh. The <MARSH> is commonly covered by thick layers of <SEDIMENT>s. 18 IR [ECORC, Wetland Surface Forms, M06]  
STD
2005/06/07		 WETLAND_SURFACE_FORM STREAM_SWAMP A <SWAMP> occurring along the <WATERBODY_BANK>s of permanent or semi-permanent streams; stream swamp. The high water table is maintained by the level of <WATER> in the stream. The <SWAMP> is seasonally inundated with subsequent sediment deposition. 19 IR [ECORC, Wetland Surface Forms, S01]  
STD
2005/06/07		 WETLAND_SURFACE_FORM STRING_BOG A <BOG> characterized by a pattern of narrow (<<WIDTH>> 2 to 3 metres), low (<<HEIGHT>> less than 1 metre) <RIDGE>s oriented at right angles to the <DIRECTION> of drainage; string bog. Wet <TERRAIN_DEPRESSION>s or pools occur between the <RIDGE>s. The <WATER> and peat are very low in nutrients because the <WATER> has been derived from other ombrotrophic wetlands. The peat <<THICKNESS>> is greater than 1 metre. 20 IR [FACC, Annex B, BOC:2] [ECORC, Wetland Surface Forms, B15]
Group membership:

In addition to the status and date information for each entry, a colour coding scheme highlights the database holding to which an entry belongs. The following highlight colours are used:

  • white - the entry is in the standard
  • yellow - the entry has been added to the register
  • pink - the entry has been submitted for inclusion in the register, but it is not approved
  • cyan - a deprecated entry that was originally either in the standard or was added to the register, but has since been deprecated

The following icons are used to identify items that have figures, modifications and/or clarification notes:

  • F n - has Figures and, if more than one figure, n figures
  • M - has Modifications
  • C - has Clarifications
