Raised bog and fen

Numéro d´article: P1521262

Principle

Bogs and fens are habitats of plants that are specialised in soils with constant excess water. Apart from this specialisation, bogs and fens differ significantly from each other. Raised bogs and fens, for example, have different plant communities, which is due to their varied conditions of life that are examined in this experiment.

Benefits

  • Experiment is part of an experiment set with numerous experiments in ecology
  • Universal handheld measurement device can also be used for other measurement parameters relevant in ecology, biology and chemistry
  • Outdoors measurement possible, for mobile use
  • Graphical display of measurement data
  • Data can be saved on SD memory card
  • All data can be transferred onto a computer for data analysis
  • Data analysis software can be freely distributed

Tasks

  1. Determination of the conductivity and the pH values of the surface water of raised bogs and fens
  2. Comparison of the measurement values of both types of water samples

What you can learn about

  • Raised bog
  • Fen
  • Plant community
  • Indicator plant
