title: BAYSICS Citizen Science Data (ecoclimatological observations, here: animal observations, focused on Bavaria)

description: This is the first dataset released from the BAYSICS project (Bayerisches Synthese-Informations-Citizen Science Portal für Klimaforschung und Wissenschaftskommunikation – Bavarian Citizen Science Information Synthesis Portal for Climate Research and Science Communication). The data in this release cover the core project phase and extend from April 2020 to March 2024. The dataset includes observations (quantities and images as submitted) and additional metadata (e.g. time and place). 
The BAYSICS web portal has been collecting citizen scientists’ observations on four main research topics: 
 
Plants - investigating the phenology of plants to track the effects of climate change. 
Allergenic Species - investigating changes in pollen loads as a result of climate change. 
Animals - exploring changes in animal distribution and behavior as a response to climate change in both urban and rural areas. 
Tree Lines - investigating the altitudinal limits of tree species in mountainous regions to understand the impacts of climate change.  
The datasets are organized to contain: 
 
one main recording table (as .xlsx and .csv) 
one .zip file with observation pictures, sorted by submission year/month/day and referenced from the table (in the “Photo” field)  
This sub-dataset comprises animal observations. The observation pictures are in baysics_animals_by202403.zip. The fields in the recording table (baysics_animals_by202403.xlsx/.csv) for ANIMALS (German: TIERE) are as follows: 
 
AnimalSpecies: Identified animal species 
Certainty: Confidence in identification 
Number: Number of individuals observed 
Observation: Activities of the species at the time of observation 
PlaceInfo: Type of area where the species was observed 
ObservationMethod: Method used to conduct the observation 
Latitude: Latitude coordinates 
Longitude: Longitude coordinates 
Position: How the position was recorded 
AccuracyGPS: (In)accuracy of GPS in meters (automatically determined when using GPS features of a smartphone) 
ObservationDate: Date of the observation 
ObservationTime: Time of the observation 
Photo: Path to the image  
Observation data has been submitted via an online form on the BAYSICS portal, where additional guidance and information has been provided to support the observation process. Data quality has been managed through a reporting system that can be used by users to flag inappropriate data. Reported data, in particular images, have been temporarily hidden and only made public after a successful verification by the project team. 
The BAYSICS data set is valuable for integrating with other climate data, such as temperature and precipitation records, to assess the impact of climate change. It also serves as ground-truth data that can be combined with remote sensing data and other sensor networks. Furthermore, the project has been promoting the FAIR principles (Findable, Accessible, Interoperable, Reusable) for citizen science data, including the availability of data to a wider community of researchers. BAYSICS has been highlighting the growing importance of citizen-generated data in scientific research. 
The project has been carried out from 2018 on in partnership by the Technical University of Munich, the Leibniz Supercomputing Center of the Bavarian Academy of Sciences and Humanities (LRZ), the Catholic University Eichstätt-Ingolstadt, the University of Applied Sciences Weihenstephan-Triesdorf, the University of Augsburg, the University of Regensburg and the Ludwig-Maximilians-Universität München. Based in Bavaria, Germany, BAYSICS has engaged citizens in research on nature dynamics, conservation, and climate change.
