Not the fertile fields or pastures, but the less productive or barren lands such as heathlands, moors and lowlands, woods and different reservoirs of water and their shores, were used as commons. They served important functions, as grazing area, and as a source of fertilizers, obtained through removing the topmost layer of the soil. In addition, they offered a variety of marginal resources especially for the lower rural classes. They were supposedly the ones who were burdened with the overuse of common areas starting at the end of the eighteenth century. The thesis of overexploitation of the rural poor was an important argument in favour of the partition of common property. No less important was a new attitude towards the agrarian landscape. For the "enlightened" middle-class observer, uncultivated land came to be regarded as a potential goldmine as well as a reserve for projected increases in agricultural productivity. Control over former barren land was tightened after the dividing of the commons and the overcoming of the agrarian crisis of the 1820s, when traditional agriculture was replaced by the methods of capitalist agriculture. In the wake of its ambitious, wide-ranging projects of improvement, the government, together with a new kind of peasant entrepreneur, discovered water as a resource instead of merely an unchangeable medium, like wind or the weather. Former barren lands thus underwent a process of drainage and irrigation with enormous consequences, not only economic and social but also ecological. Former wetlands were transformed into fertile fields, heathlands could be turned into meadows by irrigation and with the help of artificial fertilizers. This fits into a process of a general drying out of the Central European landscape and the loss of wetland vegetation and wildlife. The area under cultivation was extended greatly. At the same time, the newly created pasture and arable land was -and still is -dependent on constant water management. The appearance of today's cultural landscape is the result of a struggle which grew increasingly embittered towards the end of the nineteenth century, when conservationists entered the arena and fought for their vision of protecting spaces of nature against capitalist agriculture, as a kind of aesthetic commons.
