The Pietzmoor Bog

The Development of the Pietzmoor Bog

The Pietzmoor bog is located on the southern border of the Lüneburg Heath Nature Reserve and now covers an areas of approx. 2.5km2. It is situated in a location that is the perfect setting for a bog landscape, with a depression in the land and several water-impermeable layers of clay in the ground. Profile examinations carried out in 1975 revealed that the maximum peat depth of the bog is 7.50 metres. If we assume that the peat moss (sphagnum) grows approximately 1mm every year, the Pietzmoor bog is now nearly 8000 years old.

During its lifespan, the Pietzmoor has undergone a rather untypical development. Unlike other bogs, it was not created from a nutrient-rich lake that became a swamp and then transformed into a raised bog over time. Instead, different species of cottongrass, sedge and sphagnum started to grow in a watery depression at a very early stage after the Ice Age and continued to cover the area more and more. This form of raised bog development, in which the acidic and siliceous ground plays an important role, is characteristic of a multitude of heathland moors.

 

After being used for many centuries, this treasure almost faced its demise, but successful land restoration measures are now enabling the Pietzmoor to grow again, thus preserving it as a 'natural history book'.
