Carte du gradient du niveau trophique en Hauts de France

Carte brute issue du modèle sur les variations spatiales du pH bioindiqué de l'horizon A. C'est un modèle construit à partir de données géologiques, topographiques (MNT) et des données peuplements (IFN).. Elle permet de visualiser dans l'espace comment varie la richesse des sols avec un gradient allant des sols très acides (rouge), acide (orange), assez acide (jaune), peu acide (vert clair), neutre (vert) à calcique à calcaire en gris.
