The Argonne forest (from the Breton "Argoat", meaning "land of woods") is home to centuries-old beech and oak trees, giving this massif the appearance of a green island. The Hauts de Meuse plateau is also largely covered by beech forest, but its permeable soil favours the presence of oak, hornbeam, maple, ash and wild cherry trees and shrubs such as dogwood, hawthorn and hazel.
The half-continental, half-oceanic climate favours the appearance of carpets of anemones in spring and sees periwinkle, orchids and grasses bloom throughout the département. This forest flora is rich in animals such as wild boar, roe deer, doe and stag, which are just as interesting to naturalists as they are to gourmets.
