In Belgium, a stand of various species has been created out of a spruce monoculture that used to be gnawed by bark beetles.

In Roupage, our planting project enabled the reforestation of a plot of land populated by spruce trees, which used to be attacked by wood-eating insects. The project has been carried out with the support of our Reforest'Actors and our contributors, Puratos and Revolve.
The plot used to be populated by spruce only. Unfortunately, this species can be attacked by insects, particularly bark beetles. Those bugs essentially feed on dead wood, accelerating its decomposition and thus participating in the enrichment of soils. However, their multiplication, fostered by global warming, leads them to attack living trees, especially those already weakened following a great drought or a storm, for example.
Bark beetles dug galleries under tree bark, preventing the sap from circulating normally. Eventually, it causes the death of the spruces. A sanitary cut was thus performed to prevent the bugs from spreading.
A total of 1,244 trees of various species have been planted or protected, in order to restore a dynamic and resilient stand:
- 670 maple trees protected
- 350 beeches
- 224 sessile oaks
The planting of three different species will provide habitat for more biodiversity on the plot. The mix of coniferous and deciduous trees will thus accommodate and feed a diverse fauna!
This diversity will help the stand resist climatic hazards and insect attacks.

The planting was completed in autumn 2019. Ever since, the recovery has been excellent, reaching 95%! The owner carried out the planned clearings. Another positive note is that no game damage has been observed on site by our teams. Therefore, the planted trees continue to grow.
