ENSELY spaced hedgerows form the dominant landscape motif wherever they are found. These rectilinear arrangements of trees or shrubs occur in areas of differing physical, cultural, or economic complexity, and the motives for their implantation and persistence are diverse.1 Unlike the hedges of northwestern Europe that have long served a variety of purposes, those in the south of France are used mostly for wind abatement. The exceptional density of windbreaks in the flat, irrigated zones of Provence (Fig. i) provokes reflection on their origin, composition, and perceived role in a specialized and dynamic agricultural system.
