Description :
The elaboration of a scheme for a barrage on the river Ourthe occidentale has been for the Laboratoire d'Ecologie Végétale of the University of Louvain the incentive to an ecological landscape study of that forest valley of the Belgian Ardenne. This note gives the valuation drawn up down the valley. The ecological estimation based on valuing how rich in ecotopes a given place is can be read on a reticulate map, the value of the meshes expressing a five-class-distribution. The original method of the landscape sights makes it possible to produce an objective quantification of the landscape as a whole. Reticulate maps provide a valuation over five classes of two major parameters (the landscape observable value and the visual perceptibility frequency) and their combination into a landscape index. These valuations make it possible to quantify the impact of the projected barrage on two points: the fall in value will reach 50% or more, both for the ecological value of the sport and for the quality and the interest of its landscapes.
