GGR288H5 Lecture Notes - Lecture 9: Sphagnum, Groundwater Recharge, Ericaceae
Document Summary
Area of swamp, marsh, bog, and/or fen-whether natural or artificial, permanent, or temporary-, with water that is static or flowing (fresh, brackish or salty), including areas of marine water where depth does not exceed six meters at low tide. The world conservation monitoring centre estimates that wetlands constitute about. Bogs fens important for groundwater recharge and discharge: water cycle functioning swamps: wetland flooded in the rainy season, dominated by woody plants, waterlogged conditions (++). Marsh: wetland frequently or continually flooded, dominated by emergent herbaceous plants, waterlogged conditions (++++). Bogs: peat deposition centers (depo-centers; high water table; high organic accumulation; acidic conditions; mostly green water fed (i. e. rain); sphagnum moss, spruce, ericaceae shrubs. Fens: peat depo-centers linked to nearby habitats (upland nutrients) and from groundwater movement; high water table; less organic matter, less acidic; reflect local geo-chemistry. Related to both blue water recharge and to discharge to groundwater. Peat=dead plant material (for bogs more frequently mosses)
