Ce projet est situé en Isère dans la ville de Crets-en-Belledonne. Cette ancienne monoculture d’épicéas a été fortement affaiblie par son mode de gestion monospécifique qui facilite la propagation de maladies et de ravageurs. La composition de ce peuplement a donc favorisé l’invasion de scolytes dont il a été victime. Malheureusement, le peuplement ne montre pas de signe de régénération naturelle depuis, ce qui menace l’avenir de la forêt. Désormais, 2 100 arbres y sont plantés, l’occasion de diversifier le peuplement. Grâce à la variété des essences, la forêt sera plus résiliente face aux aléas extérieurs et au changement climatique. Cette démarche permettra aussi d’enrichir la biodiversité environnante. Par ailleurs, les arbres plantés stockeront du carbone, participant ainsi à la lutte contre le changement climatique.

Influences the quality and integrity of the soil-water system, and the cycling of water and nutrients.

Supports human well-being, by providing resources, income, education, and supporting recreation and heritage.

Contributes to the mitigation of the greenhouse effect and influences precipitation patterns and the local microclimate.

Preservation of local biodiversity by providing suitable habitats and resources.

This project is located in Isère department, in the city of Crets-en-Belledonne. This old spruce monoculture has been greatly weakened by its monospecific management - which facilitates the spread of diseases and insect pests. The composition of this population favoured the invasion of bark beetles which it was a victim of. Unfortunately, the population doesn't show any sign of regeneration since, which threatens the future of the forest. From now on, 2 100 trees are planted, which diversifies the population. Thanks to the variety of species, the forest will be more resilient against natural hazards and climate change. This process will help enrich biodiversity. Besides, the trees planted will store carbon, which will help fight climate change.
