Thanks to the possibilités to refer to the past and actual records of floristic abundance about the moors around Lessay, it can be proved that the most characteristic and interesting species have decreased. It's directly linked to the fading or to the modifications of the biotops which are absolutely necessary for them to survive. Neither this very well known biologic high grade, nor the exceptional initial size of the complex, nor the protections and ranks have managed to stop the constant and repetitive destruction of the natural heritage of this region, due to some inadequate developments.La disponibilité de données anciennes et actuelles, sur la richesse floristique des Landes de Lessay permet de prouver la réduction importante des esp...
