These soils are more poorly drained than those of map unit 3, buthave similar morphology .These soils have severe limitations for use astrails or recreation sites due to a high water table,susceptibility toflooding and ponding, and deep organic surface horizons .Soil Map Unit 5(Peaty Rego Humic Gleysol)These very poorly drained Gleysolic soils are found in areas ofgroundwater discharge on steeply sloping (topography class F) land surfaces .The water table is at or near the soil surface throughout the year andstrongly influences soil and vegetation characteristics and use potential .Vegetation characteristically consists of sedge communities withEriophorum polystachion and Carex sp .being dominant, and Senecio triangularisand Sphagnum sp . are often present in abundance .A 15 to 20 cm layer of peaty organic material (Of)overlies awater saturated soil profile .Anaerobic conditions result in dull grayreduced soil colors (gley) in the C horizons which vary in texture from
