The Bavarian Environment Agency = Bayerisches Landesamt für Umwelt (LfU) fulfills a number of official duties, among them tasks in the area of biotope mapping and species conservation. The data packages concerning vascular plants in Bavaria are gathered starting with the 1970th and provided for the project "Flora von Bayern" hereby. They mainly originate from long-term species and biotope monitoring programs run by Bavarian state agencies, e. g. the biotope monitoring as of Bavarian Lowlands and the Alpes and of the Bavarian species monitoring.
Occurrence data from survey studies of the LfU in online portals
Since 2017 a regularily updated version of these occurrence data is organised, processed and archived at the SNSB IT Zentrum using the data management system Diversity Workbench. These data records are quality-controlled and selected for online provision using data exchange schemas (ABCD and DwC standard). In the case of data portal of the Flora of Bavaria (formerly BIB) a special exchange schema and cache databases are used.
Currently (status 2018), more than 7 million plant occurrence records from biotope and species mapping programms in Bavaria are available via several national and international portals in order to receive various user groups. They are mostly categorized as observation data. The time (span) of the observation is given. The name of the observer respectively collector is not published. The locality is represented on Messtischblatt (MTB) quadrant level (i.e., official topographic maps (DTK) of Germany, GRID System TK25/4) or calculated to receive equivalent accuracy. (The calculations are explained here).
The data are available via the following portals:
Data portal of the Flora of Bavaria (BIB)
Occurrence data in Bavaria, with additional occurrence-assigned information, e. g., literature citations, and taxon-assigned information, e. g., the floristic status and images
Global Biodiversity Information Facility (GBIF)
Occurrence and checklist data worldwide, with additional occurrence-assigned information, e. g., basis of records, type status, links to images
German Federation for Biological Data (GFBio)
Occurrence and biodiversity data worldwide (provided by German research data centers), with additional occurrence-assigned information, e. g., links to images and visualisations, provided by German data centers
Nomenclature and taxonomic concepts follow the Taxonomischen Referenzliste der Gefäßpflanzen Bayerns.
Currently, the LfU data set delivered for GBIF and GFBio by a BioCASe provider software installation does not include timespan information. The representations show the start of the timespan only. If you need this information, contact the BFL data team.
The data of the online data set "Floristic records from survey studies of the Bayerisches Landesamt für Umwelt" are offered according to the regulations Richtlinien des Fachdatenzentrums der Staatlichen Naturwissenschaftlichen Sammlungen Bayerns (SNSB IT Center) zum Umgang mit Beobachtungsdaten, the special regulations to the realisation of a Flora of Bavaria and the regulations Richtlinien des Bayerischen Landesamtes für Umwelt (LfU) zum Umgang mit floristischen Daten aus dem Projekt „Flora von Bayern“.
