Welcome to Nature's Calendar


Nature's Calendar is the home for thousands of volunteers who record the signs of the seasons where they live.

It could mean noting the first ladybird or swallow seen in your garden in spring, or the first blackberry in your local wood in autumn.

You don’t have to be an expert to take part

Lots of help is given, including a free downloadable nature identification booklet.

This kind of recording has moved from being a leisure hobby to a crucial source of evidence as to how our wildlife is responding to climate change.

What next?

"Since starting to do the Nature's Calendar survey each season, I have learned so much about nature - trees, flowers, insects and birds - that I never knew before"
