Background & challenges
In 2018, chestnut trees in forests to the north of the Ile-de-France region were found to be dying out due to a pathogen causing the devastating chestnut ink disease. Provoked by an organism present in soil water, this disease penetrates the root system of trees and triggers rapid necrosis. The tree can then no longer take in water and becomes extremely susceptible to drought. It can die in just a few days.
The chestnut tree is an emblematic species of Ile-de-France and particularly well established in the forest of Montmorency with an occupancy rate of 70%. The damage is such that in 2018 the forest was classified as being in a health crisis. When the trees are diseased or dead, the ONF must then resort to sanitation cutting. Next, planting is carried out to restore healthy afforestation with more resistant species.
Through sanitation cutting and replanting 1,000 trees on a plot of land, the project aims to:
- restore forest cover that is more resilient to climate change thanks to the species installed;
- protect the habitat of deer, wild boar, foxes, badgers, endemic birds like the woodcock, amphibians, as well as many species of beetles and lepidoptera. Finally, the forest is also home to the royal fern, a species protected because of its rarity;
- restore rainwater filtration to the forested area. The forest of Montmorency is key to tackling erosion in the region;
- carbon sequestration in the soil, branches, and trunks. According to ONF calculations, over the long term (160 years) this project on the plot could sequester some 720 tonnes of CO2 per hectare, i.e. 820 tonnes of CO2 for this project;
- ultimately produce timber by exploiting this forest for the next 160 years.

Works timeline
Beginning of December 2019: soil preparation using mechanical digger
February 2020: planting
2021 or 2022: partition grinding if necessary
2023: replenishing if regrowth is under 80%
2025-2030: the first clearing operations to be every five years
First thinning operation 35 years after planting
Logging of the forested area after around 160 years
