Estimate of Switzerland’s Organic Soil Surface, 2015
The 2015 estimate of Switzerland’s organic soil surface used the approach of collating existing information sources (e.g., soil maps, geology maps, forest habitat maps, historical observations of peatlands, as well as inventories of fens and raised bogs) to generate an estimate or the current extent of organic soils. In a first step, the information sources were assessed for their reliability as a source of information about organic soils, spatial precision and spatial accuracy. This was carried out mostly by studying the metadata of information source, as well as comparing each data set to more reliable data sets, e.g., soil maps. For two information sources however (forest habitat maps and the fen inventory), field work was carried out to assess their suitability and reliability. In a second step the data sets were harmonized and inserted into a data model, allowing the semi-automatic combination of the various data sets. In a third step, the data sets were combined (more specifically, overlain) and a rule-based method was used to characterise the resulting surfaces as organic soil, or not organic soil. In a fourth step, information on the mineral soil surface was used to delete surfaces for which the evidence of mineral soil was stronger.
The soil surface recommended for use in most applications is 27,813 ha. This corresponds to the ‘less conservative’ estimate or organic soils, excluding those surfaces for which there was contradictory information from mineral data sets.
Because of the heterogeneous nature of the information sources that were used to generate this indicator map, it is not possible to define the scale for which this map is appropriate. The following recommendation can however be made: The map is suitable for use at the regional scale (e.g., cantonal or district, ca. 1:100,000) and larger scale only; it is unsuitable for field-scale use.
The technical report (Wüst-Galley, Andreas Grünig, Jens Leifeld (2015) “Locating organic soils for the greenhouse gas inventory” Agroscope Science 26, 100 pp.) describes the above-mentioned steps and information sources in detail, and it is strongly recommended that this report should be read by anybody wanting to use this data set.
The information sources that were used to generate the map were collated mostly in 2012-2013. This map will be superseded by a newer estimate of Switzerland’s soil surface, in 2024 / 2025.
