A varied vegetation
Since its declassification, the quarry battery has been overgrown with vegetation. The shooting ranges and the exterior barrier are now covered with trees. The main species are oak (Quercus pubescens), maple (Campestre Acer), hawthorn (Crataegus monogyna), cherry (Prunus mahaleb) and common white beam (Sorbus aria).
On the edge of the wooded area, on the crossings and the barracks, grow spingle (Evonymus europaeus) whose fruits, pink capsules showing orange seeds at maturity, are often called "bishop's caps", the dogwood (Cornus mas), the wayfaring tree (Viburnum lantana).
