Status	Attribute label	Enumerant label ▾	Concept definition	Code	Ref type	Reference	Supplemental references
STD 2005/06/07	WETLAND_SURFACE_FORM	PEAT_PLATEAU_BOG	A <BOG> composed of perennially frozen peat rising abruptly about 1 metre from the surrounding unfrozen fen; peat plateau bog. The <SURFACE> is relatively flat and even, and commonly covers large areas. The peat was originally deposited in a non-permafrost environment and is associated in many places with collapse scar <BOG>s or fens.	11	IR	[ECORC, Wetland Surface Forms, B07]
STD 2005/06/07	WETLAND_SURFACE_FORM	POLYGONAL_PEAT_PLATEAU- _BOG	A perennially frozen <BOG> rising approximately 1 metre above the surrounding fen; polygonal peat plateau bog. The <SURFACE> is relatively flat, scored by a polygonal pattern of <TRENCH>s that developed over wedges of <ICE>. The permafrost and wedges of <ICE> developed in peat originally deposited in a non-permafrost environment.	12	IR	[ECORC, Wetland Surface Forms, B05]
STD 2005/06/07	WETLAND_SURFACE_FORM	SHALLOW_BASIN_MARSH	A <MARSH> occurring in a uniformly shallow marsh depression or swale, having a gradual gradient from an often poorly defined edge to the deepest portion, and whose water levels fluctuate rapidly; shallow basin marsh.	13	IR	[ECORC, Wetland Surface Forms, M11]
STD 2005/06/07	WETLAND_SURFACE_FORM	SHORE_FEN	A fen with an anchored surface mat that forms the <SHORE> of a pond or <LAKE>. The rooting zone is affected by the <WATER> of the <WATERBODY> at both normal and flood levels.	14	IR	[ECORC, Wetland Surface Forms, F07]
STD 2005/06/07	WETLAND_SURFACE_FORM	SHORE_MARSH	A <MARSH> occupying the <REGION> between high and low water marks bordering semi-permanent or permanent <LAKE>s; shore marsh. The <MARSH>, usually found along protected <SHORELINE>s, behind barrier <BEACH>s in <LAGOON>s, on <ISLAND>s, or in embayments, is subject to flooding by a rise in the level of the <LAKE>, <WIND_WAVE>s, or <RUN_OFF>.	15	IR	[ECORC, Wetland Surface Forms, M14]
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]

PHYSIOGRAPHY

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
