Environment and society Transformation of 'small structures' and stream courses 1977–2003 Definitions/Comments: Transformation of the countryside has been analysed based on the changes in maps (sample survey of surface areas). Periods of observation correspond to the rhythm with which Swiss maps have been renewed (e.g. the 1972–1977 edition is compared to 1978–1983 edition; in the diagrams, however, only the last year is shown). Single trees: detached trees, trees in a group or array which are not part of the open forest or hedges. Hedges: striking array of trees or bushes. Source: FOEN (2007), Landschaft unter Druck. 3.
