As residents were complaining about loud noise and debris between the main road and the Etang de Chevrise, agents from the Réserve Nnaturelle went to see what the problem was. There they could see that a mechanical shovel had dug between three and four meters deep, close to the funeral parlor, and a large volume of earth and rubble had been used to fill in below the pond, but not where the water is, and that area belongs to the Conservatoire du Littoral and is managed by the Réserve. Yet the nature of the material, especially in case of heavy rain, represents a real threat of creating silt in the pond, and the Réserve remains vigilant in its surveillance of this worksite. Additional expertise will determine if such encroachment by depositing such materials on land already classified under a biotope protection order is possible, and see what to do about it.
