Arbres et groupes d'arbres remarquables (AHREM)
What this layer shows
Tree or group of trees entered on the Walloon list of arbres et haies remarquables. Felling, severe pruning or any substantial alteration require a permis d'urbanisme under the CoDT: this is a check to run as soon as a project comes near a property boundary. The measurements and the year of observation may go back several decades; an on-site survey remains necessary.

Constraints
What a consultancy or a notary checks first in Wallonia: Natura 2000 and its unités de gestion, reserves and Ramsar sites, plan de secteur and additional prescriptions, flood zones and karst, abstraction points, listed properties and remarkable trees, pre-emption, sites à réaménager and Habitat Permanent. The other municipal instruments and the rest of the water have their own set.
