Description :
Field surveys were carried out with aerial photo interpretation and vegetation mapping on the island of Stord (W Norway). Spatial analysis was carried out using GIS. Historical sources were used to generate information on land-use during recent centuries. Supplementary methods consisted of soil profile analysis and dendrochronology. Climate data were used to analyse climatic trends in the past 90 years since 1923. Forest expansion was a major trend during 1956–1994. Forestation continued during 1994–2003 and 2003–2007, but at rates far lower than in the previous period. The different starting times of forestation is reflected in the present age structure of the forest stands on the 8 landholdings studied. The conclusion is drawn that changes in land-use are the major driving force behind the distinct process of forestation that occurred during the 20th century.
