 In Europe, afforestation has become an important issue during the last few decades. Partly as a response to changing conditions for agriculture, partly following a demand for nature conservation, environmental protection and recreational facilities. The national goal for Denmark is a doubling of the current forest cover of 11% in a "tree generation", i.e. 80 to 120 years, as expressed in the Forest Act of 1989. The study site used in this study is Vendsyssel in Northern Jutland. Today, the average forest cover within the study area is 9.5 per cent, but even within this limited area, forests are very unevenly distributed.

As an example of the possible use of spatial metrics and moving-windows methods in planning at regional level, the impact on landscape structure of different afforestation strategies is assessed in this paper. A number of common GIS and image processing operations have been used to create different scenarios that represent very different afforestation strategies. Changes in spatial metrics and Hemeroby index values were compared with the present situation.
