The Pladias Database contains critically revised data on Czech flora and vegetation managed by the Department of Botany and Zoology, Faculty of Science, Masaryk University (MU) and the Institute of Botany, The Czech Academy of Sciences (IBOT), including data files provided by other institutions or individuals (hereafter "providers"). Its aim is to promote the use of data on plant diversity of the Czech Republic for the purposes of scientific research, education, nature conservation and environmental assessment. The decisions about the concept of the database, inclusion of specific data files and data provision are made by the Management Board of the Pladias Database (hereafter "Governing Board", Appendix 1), which follows these Rules and respects the observance of the interests and rights of the individual providers.
The decisions about the inclusion of particular data files into the database are taken by the Governing Board. The provider is responsible for obtaining permission to transmit data to the Pladias Database from any other parties that may have property or intellectual rights to these data or their subsets. Provider of each data set specifies to what extent and under what conditions the data may be used or provided to third parties. The Governing Board supports the largest possible public availability of data, while respecting the rights of providers to restrict the public access to their data, and securing compliance with the conditions of use set by data providers.
Public data (both freely available and available after registration) can be used for basic and applied scientific research, teaching, nature conservation and environmental assessment. Their potential use for commercial purposes is subject to approval by the Governing Board or the provider of particular data subsets. The use of data for the purposes of funded projects or expert reports contracts by governmental, educational and research institutions, and NGOs is not considered as commercial use.
Non-public data can be provided upon request sent by e-mail to members of the Management Board (Appendix 1). The application must contain a delimitation of the extent of the required data, description of the purpose of their use, and specification of the final product (e.g. publication, research report or educational presentation). If the expected data use assumes cooperation of several people, their nominal list is added to the application. The decision about the provision of species trait data and conditions of their use for the given purpose is made by their provider or, in the case of trait data owned by MU or IBOT, or species distribution data, by the Governing Board.
When using any data from the Pladias Database (including distribution maps) in publications, research reports or teaching and public presentations, the user specifies the data source "Pladias – A Database of Czech Flora and Vegetation, www.pladias.cz", or (especially in the scientific literature) cites the article with a basic description of the database (after it is published). 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. https://doi.org/10.23855/preslia.2019.001. When using specific plant trait data or species lists 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 (especially Flora of the Czech Republic, Vegetation of the Czech Republic, Phytocartographic Syntheses of the Czech Republic and articles with species distribution maps published in the journal Preslia), the user cites only those 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".
Public or non-public data obtained from the Pladias Database must not to be transferred to other institutions or persons, or posted on the Internet. The exception is sharing them with colleagues working on a project that uses specific data (in the case of non-public data after prior approval by the provider or by the Governing Board).
The user of data obtained from the Pladias Database helps to improve the quality of the database by reporting any detected errors in the data to the Governing Board or the provider of the particular data file.
The regional phytogeographical division of the Czech Republic was prepared for the purpose of the Flora of the Czech Republic (Skalický 1988). It recognizes three phytogeographical regions based on the dominant flora and vegetation: Thermophyticum, Mesophyticum and Oreophyticum, including in turn areas with thermophilous flora and vegetation with continental and submediterranean affinities, mesophilous flora and vegetation typical of the European temperate zone, and mountain flora and vegetation with boreal and arctic affinities. Each of these three regions is subdivided into two provinces: Thermophyticum into Bohemian Thermophyticum and Pannonian Thermophyticum, Mesophyticum into Bohemian-Moravian Mesophyticum and Carpathian Mesophyticum, and Oreophyticum into Bohemian-Moravian Oreophyticum and Carpathian Oreophyticum. These provinces are further subdivided into 99 phytogeographical districts, of which 21 are in Thermophyticum, 63 in Mesophyticum and 15 in Oreophyticum. Some of the districts are subdivided into subdistricts.
The map and shape files are based on digitized hand-made unpublished fine-resolution maps that were prepared by the team of authors of the Flora of the Czech Republic in the 1980s and slightly differ from the coarse-resolution map published in the first volume of the Flora (Skalický 1988). A map based on this digitized version was first published by Kaplan (2012).

The file contains the definition of the grid used for the Central European flora mapping. The basic cells of this grid (Central European Basic Area, CEBA) measure 10 × 6 minutes (10 in the west–east direction, 6 in the south–north direction), which corresponds to approximately 12.0 × 11.1 km (133.2 km2) on the 50th parallel. The Czech Republic comprises 679 of these basic cells including incomplete ones on the state borders. The basic grid cells can be divided into four quadrants measuring approximately 6.0 × 5.55 km (33.3 km2) on the 50th parallel.
