  PT PT: Peat and other highly organic <SOIL>s. 6
WETLAND_SURFACE_FORM   The type and/or structure of a <WETLAND>; the wetland surface form.  
  ATLANTIC_PLATEAU_BOG A <BOG> with a flat to undulating <SURFACE> raised above the surrounding <LAND>. The edges of the <BOG> commonly slope steeply downwards to the mineral soil <LAND>; an Atlantic plateau bog. Large pools scattered on the <BOG> reach depths of 2 to 4 metres. 1
  BASIN_BOG A <BOG> situated in a basin with essentially closed drainage that receives <WATER> from <PRECIPITATION> and <RUN_OFF> from the immediate surroundings; a basin bog. The <SURFACE> of the <BOG> is flat with peat generally deepest at the centre. 2
  BASIN_SWAMP A <SWAMP> developed in a topographically defined basin where <WATER> derived locally may be augmented by drainage from other parts of the watershed; a basin swamp. Accumulation of well-decomposed peat is shallow (less than 0,5 metre) at the edge but may reach 2 metres at the centre. 3
  BLANKET_BOG A <BOG> consisting of extensive peat deposits that occur more or less uniformly over gently sloping hills and valleys; a blanket bog. 4
  DOMED_BOG A large <BOG> (<<OUTSIDE_DIAMETER>> usually greater than 500 metres) with a convex <SURFACE> rising several metres above the surrounding <LAND>; a domed bog. The centre usually drains in all <DIRECTION>s; small crescentic pools commonly form around the highest point; a concentric pattern is formed if the highest point is in the centre, while an eccentric pattern is formed if the highest point is off-centre. Peat development is usually greater than 3 metres deep. 5
  FLAT_BOG A <BOG> having a flat, featureless <SURFACE> and occurring in broad, poorly defined <TERRAIN_DEPRESSION>s; a flat bog. The depth of peat is generally uniform. 6
  HORIZONTAL_FEN A fen with a gently sloping, featureless <SURFACE>; a horizontal fen. Occupies broad, often ill-defined depressions and may interconnect with other fens. Peat accumulation is generally uniform. 7
  LOWLAND_POLYGON_BOG A <BOG> with flat-topped or convex peat <SURFACE>s (often referred to as "high-centre polygons") separated by <TRENCH>s over wedges of <ICE> that form a polygonal pattern when viewed from above; lowland polygon bog. The peat was deposited in a permafrost environment as shown by internal structures. 8
  NORTHERN_RIBBED_FEN A fen with parallel, low peat <RIDGE>s ("strings") alternating with wet hollows or shallow pools, oriented across the major slope at right angles to water movement; a northern ribbed fen. The depth of peat is greater than 1 metre. 9
  PALSA_BOG A type of peat <BOG> with a core of <ICE>, formed adjacent to a mound of <SOIL> that was pushed up by or formed near the edge of a <GLACIER>; found in alpine and arctic regions; a palsa bog. 10
  PEAT_PLATEAU_BOG A <BOG> composed of perennially frozen peat rising abruptly about 1 metre from the surrounding unfrozen fen; the <SURFACE> is relatively flat and even, and commonly covers large areas; a peat plateau bog. The peat was originally deposited in a non-permafrost environment and is associated in many places with collapse scar <BOG>s or fens. 11
  POLYGONAL_PEAT_PLATEAU_BOG A perennially frozen <BOG> rising approximately 1 metre above the surrounding fen; the <SURFACE> is relatively flat, scored by a polygonal pattern of <TRENCH>s that developed over wedges of <ICE>; a polygonal peat plateau bog. The permafrost and wedges of <ICE> developed in peat originally deposited in a non-permafrost environment. 12
  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
  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 <LAKE> at both normal and flood levels. 14
  SHORE_MARSH A <MARSH> occupying the <REGION> between high and low water marks bordering semi-permanent or permanent <LAKE>s; a 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
  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
  SLOPE_FEN A fen occurring mainly on slow-draining, nutrient-enriched seepage slopes; a slope fen. Pools are usually absent, but wet seepage tracks may occur. Peat <<THICKNESS>> is usually less than 2 metres deep. 17
  STREAM_MARSH A <MARSH> occupying <SHORELINE>s, <SAND_BAR>s, stream beds, or <ISLAND>s in continuously flowing <MARSH> that is subject to prolonged annual flooding and is commonly covered by thick layers of sediments; a stream marsh. 18
  STREAM_SWAMP A <SWAMP> occurring along the <WATERBODY_BANK>s of permanent or semi-permanent streams; a 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
  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; wet <TERRAIN_DEPRESSION>s or pools occur between the <RIDGE>s; a string bog. 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
  VENEER_BOG A <BOG> occurring on gently sloping <LAND> underlain by generally discontinuous <PERMAFROST>; a veneer bog. Although drainage is predominantly below the <SURFACE>, overland flow occurs in poorly defined drain ways during peak <RUN_OFF>. Peat <<THICKNESS>> is usually less than 1,5 metres. 21
