This study is about evolution of landscapes in the slopes of low mountains. The rural exodus has transformed the XXth century’s landscapes of low and middle mountains, with the development of large forests of conifers and deciduous trees. While this dynamic is well-known in other French mountains, as the Massif Central and in Les Vosges, it has not been studied in the Jura mountains. We propose to think about the actions that we could implement to re-open the landscape of the slopes in the low mountain of the Revermont, which is the first buttresses of the Jura mountains in the Ain department (France). This study analyses both literature documents and interviews with people in the field. A definition of the phenomenon of “landscape closure” is proposed to check if it is the process involved on the studied territory. After validating this assumption, we study the Conservation Status of the open spaces of the slopes. We then identify the various actions to maintain or promote these spaces. To conclude this study, 3 scenarios are suggested to enhance the landscape slopes of the territory.
