Preserving sensitive ecosystems

Preserving habitats of community interest

The specific studied habitat is the acidic holly beech tree, found in a fairly rainy Atlantic climate and at an altitude of more than 500 m. Several indicator species of this type of habitat are found, such as blueberry (Vaccinium myrtillus) and rockfish (Galium saxatile).

Atlantic hollyhock beech wood is represented by a tree-dominated stratum of beech, accompanied by willow birch and mountain ash, where the holly is very present, as well as a grassy carpet overlapping.

This habitat often takes its place after the abandonment of agropastoral areas. It can also be linked to silvicultural management with coppices under beech forest. These beech stands are often transformed into coniferous stands, which is a serious threat.

Vigilance maps for this habitat in the Natura 2000 zone are produced and allow to propose new silvicultural management routes in the context of climate change.
