  • woodruff beech forestst


  • wood hairgrass beech forests

  • hard- and softwood alluvial forests
  • alder swamp forests

Overview

correlating main forest types

  • weichselian moraines - east


  • central sandy deposits - center

  • holocene marshes - west





Main landscape types

woodruff beech forests

  • main species red beech
  • ca 35 m, dense tree crown
  • rich ground vegetation, blooms very colourful in early spring
  • deadwood is habitat for many animal species

located on weichselian moraines

woodruff beech forests

  • sandy, low pH soils

  • red beech main species


  • not much ground vegetation

crinkled hairgrass beech forests

central sandy deposits

crinkled hairgrass beech forests

Alluvial woods

  • flooded less frequently
  • wet for shorter time period
  • higher over water level
  • mainly populatet by oaks, ash trees and elms

hardwooded

  • flooded often
  • wet for long time period
  • lower and close to water level
  • mainly populatet by willows

softwooded

alder swamp forests

  • permanet high water levels
  • only small fluctuation
  • mainly populatet by alder trees, adjustet to wet habitats
  • home for animals adapted to water

holocene marshes

human impact

  • large areas of beech forests replaced for wood production
  • deadwood gets removed by forestry
  • general loss of forest area
