Why we record

Nature’s Calendar observations help us predict how wildlife will be affected as the climate changes.

The Nature’s Calendar database currently contains 2.9 million records. It is believed to be the longest written biological record of its kind in the UK. Its data is used by researchers from across the world to explore the effects of weather and climate on timings in wildlife.
