Description
EUR_OXY_SPH_Expert_system_file is an expert system for automatic classification of European bog vegetation plots of Oxycocco-Sphagnetea class. The expert system allows classification of new vegetation plots to seven alliances (Ericion tetralicis, Oxycocco-Ericion tetralicis, Erico mackaianae-Sphagnion papillosi, Oxycocco microcarpi-Empetrion hermaphroditi, Sphagnion medii, Rubo chamaemori-Dicranion elongati, Sphagno baltici-Trichophorion cespitosi).
In short: The Oxycocco-Sphagnetea class is defined on the basis of the ratio between the sum of square-root transformed percentage covers of 'Bog species' (groups ##D +01 Bog-species-vascular, ##D +02 Bog-species-bryophytes), and the sum of square-root transformed percentage covers of species occurring in bog hollows and species occurring out of the bog habitat (groups ##D +01 Vascular_negative, ##D +02 Bryophytes_negative). Similarly, for classification of a plot to an alliance, the plot must contain a greater proportion of discriminating species group of a certain alliance than that of other alliances. Compliance with more stringent conditions will allow direct classification, while other plots will be assigned only on the basis of the result given by the ratio of species covers. This makes it possible to classify all plots to alliances. The use of discriminating species groups excludes the possibility of classifying a vegetation-plot record in more than one group at the same hierarchical level.
The principles of the expert system follow the methods described by Chytrý et al. (2020) .
The classification of a set of vegetation plots can be run in the JUICE program (Tichý 2002; https://www.sci.muni.cz/botany/juice/), TURBOVEG 3 program (Hennekens 2015) and an R script developed by H. Bruelheide et al. (2021).
