BgMA-ESy: Expert system for automatic classification of vegetation plots of subalpine tall-herb vegetation (class Mulgedio-Aconitetea) from Bulgaria

***** BgMA-ESy is an expert system that classifies vegetation plots of the class Mulgedio-Aconitetea (Mucina et al. 2016) occurring in Bulgaria. The expert system can be run using the JUICE program (Tichý 2002; https://www.sci.muni.cz/botany/juice/). The aggregation of vascular plants included within the BgMA-ESy is adopted from EUNIS-ESy (Chytrý et al. 2020; https://doi.org/10.5281/zenodo.4812736), and in a few cases, it is adjusted. ***** Specifications The analyzed data (vegetation plots) cannot: include scrub vegetation (cover of tall shrub species > 8%; e.g., Pinus mugo, Salix spp.). contain tree species with cover > 1% (e.g., Fagus sylvatica, Picea abies). contain Pteridium aquilinum as a dominant species. The expert system was trained on vegetation plots with 5–100 m2 area that occur above 1000 m a. s. l. * Exceptions from EUNIS-ESy aggregation: Heracleum sphondylium agg. does not include H. sphondylium subsp. verticillatum. ***** When using this work, please cite: Szokala D., Kočí M. & Vassilev K.
