This article explores the environmental transformation of the moorland (landes) of southwestern France from a much maligned “wilderness” or “empty space” to a forested landscape coveted for its productive potential as well as its aesthetic beauty. This occurred in two stages from the eighteenth century to the present and was effected by the French state and local landowners. It bears resemblance to processes of environmental change in North America, Central Asia, and Africa, where states and colonial or imperial powers took measures to develop alleged empty spaces through seizure, development, and settlement. Drawing on paradigms of colonial rule and Henri Lefebvre’s theory regarding the production of space, the article examines the eradication of the “wilderness” of the region of the Landes, which led to the displacement of its pastoral populations and the end of their way of life. It explores the role of technology in consolidating the power of territorial states and empires and the significance of the parallels that can be drawn between the Landes and France’s overseas empire. Finally, it attests to the porosity of the boundary between man-made and natural landscapes, while illuminating the process by which the artificial forested landscape of the Landes ironically came to be redefined and revalorized as “natural” national heritage that was ripe for environmental protection by the second half of the twentieth century.
