Pladias Database of the Czech flora and vegetation

The Pladias (Plant Diversity Analysis and Synthesis) Database of the Czech Flora Vegetation was developed by project team in 2014–2018 has been continuously updated since then. flora section database contains critically revised information on vascular flora, including 13.6 million plant occurrence records, which are dynamically displayed maps, data 120 characteristics (traits, environmental associations other information), divided into sections: (1) Habitus growth type, (2) Leaf, (3) Flower, (4) Fruit, seed dispersal, (5) Belowground organs clonality, (6) Trophic mode, (7) Karyology, (8) Taxon origin, (9) Ecological indicator values, (10) Habitat sociology, (11) Distribution frequency, (12) Threats protection. vegetation types extracted from monograph Republic. supplemented national botanical bibliographies, electronic versions standard monographs, a more than 19,000 pictures taxa types, digital maps (shapefiles) with information. available online public portal www.pladias.cz, also provides download options for various datasets identification keys to species In this paper, we describe general scope, structure content database, details characteristics. To illustrate main geographic patterns selected characteristics, provide mean values numerical or proportions categories categorical map country grid 5 longitudinal × 3 latitudinal minutes (approximately 6.0 km 5.5 km). We summarize variation functional traits using principal component analysis.
