Context and bénéfits
This parcel was previously made up of a few Douglas fir and pectinated fir trees but mostly of Sitka spruces. In recent years, they have been attacked by a beetle, the scolyte. This insect is a member of the bark beetle family and attacks spruce forests, which are mountain ranges populated by spruces. In order to limit the proliferation of the pest it is necessary to cut down affected trees as well as the weakest ones that will not resist.
This tree planting project will restore a degraded ecosystem, strengthen the reception of biodiversity, and make the stand more stable with a diversity of species. Indeed, Douglas fir, Nordmann fir and sessile oak are planted. In addition, some hardwoods naturally arrive at the edge, they will allow a better resistance to climatic hazards.
This planting project uses the innovative mycorrhization technique, which aims to promote tree growth and strengthen tree resistance to pathogens and water stress. In practice, the roots of young plants are selected for their adaptation to the soil and climate change. They will be coated on the day of the mushroom planting. The association created between these fungi and the roots will form mycorrhizae that will promote the supply of water and nutrients to the trees. The soils will benefit from a liquid treatment composed of bacteria as fundamental to their regeneration as to the nutrition of the trees.
