Varambon forest is very old. It is primarily comprised of firs trees, spruces, beech trees, maple trees and rowan trees, and was partly used for livestock. Managed according to the selection system by foresters during the 19th and 20th centuries, this forest is still of major biological interest. As a part of the National Natural Reserve created in 1993, it must remain a calm and tranquil area to encourage the western capercaillie, the hazel grouse and many other birds to continue to come (excerpt of the booklet: “Au fil de l’alpage” or “Through the alpine pasture”).
