This is a forest area that covers part of the Mont Vengé plateau, a limestone formation that rises above the surrounding plains. The forest is composed mainly of oaks and hornbeams on the plateau and a mixed oak and beech forest on the slope. The forest is home to various species of birds, mammals, insects and plants, some of which are rare or protected. For example, there are the green woodpecker, the red-backed shrike, the hazel dormouse, the horseshoe bat and the swallow-tailed butterfly. The Bois de la Montagne forest in Changey is a magnificent and varied place to explore and enjoy.
