For nature and climate research, it is becoming increasingly important to know when the plants start to bloom, fruit or shed the leaves and the animals are active. With the app you can photograph animals and plants, enter what they are doing and thus help climate research. The natural calendar runs on the SPOTTERON Citizen Science platform.

Climate research for the whole world
Your observations flow into the European phenological database, which is maintained by the Central Institute for Meteorology and Geodynamics. This makes them useful for climate researchers all over the world.
