Change of land use classes and vegetation types between 1927 and 2013 south of Linköping (English)
Abstract [en]

In 1927, the forest in Östergötland was inventoried for the first time by Riksskogstaxeringen. The original, hand-written field protocols have recently been digitized. This made it possible to repeat the fieldwork in the same transects and using the same methodology. The purpose of this study was to re-inventory an area in Sweden south of Linköping to assess changes in land use classes and vegetation types. Another purpose was to identify practical problems with the re-inventory as well as get an idea of the type of questions that are possible to address. A total of 45 two kilometers transects were inventoried in an area that covers much of Linköping oak woodlands. The results show that forests, moors and various impediments had increased since 1927. By contrast, rock outcrop, pastures and more intensively used farmlands had significantly decreased. Among forest types, spruce forest had increased while spruce/pine forest and broad-leaf/pine forest had decreased in the study area. My conclusion is that it is possible to perform re-surveys using the same methodology that was used in 1927. Representative data for all parameters may be difficult to obtain because some methodological descriptions are inadequate. The ratings used for land-use classes are generally clear and the results based on them are thus likely to be representative for the area. Because of problems to classify forest types, however, conclusions regarding them are less reliable.
