Context

In the North of the  Jura district, the forest plot of Chamblay was originally made up of a monospecific stand of spruce trees. The plantation was heavily affected by the Bostryche.

The bostryche is a species of bark beetle. They are wood-eating insects that feed on wood. They belong to the order Coleoptera, just like ladybirds and beetles. Normally, they feed mainly on dead wood, thus accelerating its decomposition, which greatly benefits the enrichment of the soil. However, when the population of these insects is too large for the dead wood resource, or when trees are weakened (after a period of severe drought or storm, for example), they may attack living trees. They then dig a network of galleries under the bark of trees to feed and reproduce. These boreholes affect the trees, disrupting and limiting the circulation of their sap and altering their development. These weakenings can lead to the death of the tree. 

The forest was recently acquired by its new owners, who wish to reforest the plot that was laid bare due to the trees' dieback.

The planting of various species on this plot is a key point of the project, since it will allow the plot to be revitalized, in particular with the integration of forest species adapted to the station, which will increase the resistance of the stands to diseases and climatic hazards. The resulting forest will thus be more resilient, capable of creating various habitats and providing varied food for local biodiversity.
