  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
  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
  VENEER_BOG A <BOG> occurring on gently sloping <LAND> underlain by generally discontinuous <PERMAFROST>; veneer bog.
