Here you can submit user reports on specific development phases of plants. These are used by the DWD, among other things, to obtain a better assessment of the current plant development in Germany. From this, conclusions can be drawn about climatic changes. In addition, the messages are displayed within the WarnWetter-App.

Via the guided dialog, the development phase of the plant (=stage, e.g. beginning of flowering), plant species, as well as location (automatically from coarsened GPS, from image data or manually) and date are queried. To verify the report, a photo of the observed plant should -if possible- be sent. Information for the DWD can be entered in a free text field. There is also the option to report other plant observations via "Other stage" and "Other plant species". In this case, a photo is mandatory. Subsequent reporting is possible by manually entering date and location.

To ensure data quality and for legal reasons, we use various methods to check the authenticity of the report and to rule out misuse of the function. If necessary, messages are objected to by the corresponding checking algorithms and are therefore not published. However, these messages are still sent internally to the German National Meteorological Service for further analysis. In the event of improper use, the DWD reserves the right to block the function for individual users.

Important: Please make sure that no persons or body parts are visible in the photos. Otherwise, the affected messages will be automatically discarded by the quality assurance.

Please also note the terms of use for user reports and the disclaimer (in German)
