Sphagnum is the foundation of a raised bog. To improve the situation in areas formerly used for peat cutting or pasture, sphagnum growth is very important. Sphagnum will absorb water, and then the area will get wetter. Sphagnum will also make the area more acidic. This will improve the conditions for vegetation naturally occurring in a raised bog. It will also make it harder for plants that are not adapted to this environment to survive. Thus, growth of sphagnum is a first step towards getting back the naturally occurring vegetation.
Sphagnum is the foundation of a raised bog
The preserved areas of raised bog in Lille Vildmose are fragmented. Consequently, it will take a long time for sphagnum to immigrate on its own. If sphagnum spreads faster, it can speed up the process of raised bog restoration.
In a demonstration project, sphagnum is spread in areas formerly used for peat cutting. The objective is to investigate whether this can speed up the restoration of severely damaged raised bog. This has been tested in Lille Vildmose before, but only in a small-scale project. In this project, the testing will be conducted in larger scale. The test is expected to be conducted in two areas, each covering approximately 10 ha.
Before sphagnum is spread, the top soil is removed. It is too rich in nutrients. Fresh sphagnum is harvested from another raised bog. It is then cut in small pieces and spread on top of the dark peat soil.
Sphagnum has recently been spread out on an area in Mou-fenner
