Planting operations are underway at the regional natural space of the Moulin des Marais, north of the woods and along the path leading to the Fontaine Gravier pond. These new plantings will replace the dangerous ash trees affected by chalarose that had to be removed in 2024.
The work is being managed by Île-de-France Nature, responsible for the site's development and management. The preliminary stage, which began in early October, involves preparing the soil and clearing the affected plots, notably by removing invasive young sycamore maples that have started to colonize them. Planting will follow in early November, depending on the technical constraints of the project and weather conditions.
A total of 1,600 trees will be installed, including alder, willow, field maple, service tree, pedunculate oak, common maple, and common walnut. These species were chosen for their increased resilience to climate warming and various diseases, thereby ensuring the good health and renewal of the woodlands.
For safety reasons, entry into the work areas is prohibited.
