Delineation of mountains and mountain areas in Europe - a planning approach

Journal of the Geographical Institute Jovan Cvijic, SASA, 2015
Mountains are usually understood as high elevation areas, which are sparsely populated and where nature is preserved. The elevation above sea level is the most commonly taken as a criterion for mountain delineation, but the complexity of the task arises when definitions are compared in different national contexts, between projects and particularly when
