Bog woodland

In Wallonia, wooded peat bogs are represented only by sphagnum peat bogs, which are boreal forests occupying damp, highly acid peaty soils, mainly in the Upper Ardennes. These are clear, low woodlands dominated by downy birch (Betula pubescens). Shrubby vegetation is sparse, and mainly consists of the eared willow (Salix aurita). The bryophytic flora, consisting mainly of sphagnum moss, is almost completely covered, which is characteristic of this habitat. The flora includes a majority of boreal species, in particular the purple moor-grass (Molinia caerulea) and the european blueberry (Vaccinium myrtillus).

These forests correspond either to the woody colonisation of certain acid low marshes, acid rush swamps or peaty heaths with moor-grass, or to forests on creeks of very acid water seeps, or to afforestation phases of sphagnum bogs.

In 2015, at the level of the project's Natura 2000 sites, this habitat represented 142 hectares. The aim of the project was to recreate/restore 25 hectares of bog woodland.
