About the project

Pladias (Plant Diversity Analysis and Synthesis Centre) was a project funded by the Czech Science Foundation in 2014–2018. It integrated research capacities dealing with the diversity of temperate flora and vegetation from Masaryk University (Brno), Institute of Botany of The Czech Academy of Sciences and the University of South Bohemia in České Budějovice, in cooperation with many external specialists. An extensive database of critically revised data on Czech flora and vegetation, available at this web portal, was created as an infrastructure to support research within this project. It is continuously updated also after the end of the Pladias project.

The database focuses on native and naturalized flora occurring in the Czech Republic. Cultivated plants are not within the scope of the database, although the most commonly cultivated crops and woody plants are included.

The taxon concepts and nomenclature largely follow Danihelka J., Chrtek J. Jr. & Kaplan Z. (2012): Checklist of vascular plants of the Czech Republic. – Preslia 84: 647–811. The names of newly recorded and some other taxa follow the submitted manuscript of the second volume of Key to the Flora of the Czech Republic (Kaplan et al. 2019).

When using data from the web portal Pladias.cz, the source has to be referred to as “Pladias – Database of the Czech Flora and Vegetation, www.pladias.cz”. When using species distribution data, the user also cites the article Wild J., Kaplan Z., Danihelka J., Petřík P., Chytrý M., Novotný P., Rohn M., Šulc V., Brůna J., Chobot K., Ekrt L., Holubová D., Knollová I., Kocián P., Štech M., Štěpánek J. & Zouhar V. (2019): Plant distribution data for the Czech Republic integrated in the Pladias database. – Preslia 91: 1–24. When using specific plant trait data, the user also cites the original sources referred to in the Pladias Database. When using texts or images that the Pladias Database has taken from published sources, the user only cites the published sources. When using images of plants or vegetation types from the Pladias Database website, the user quotes the author of the image and the source “www.pladias.cz”.
