BBC’s Springwatch are asking everyone to look out for signs of spring by monitoring some commonly seen natural events. From this they aim to calculate how fast the arrival of spring 2015 sweeps across the UK from south to north.

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.

Check out the BBC’s website http://www.bbc.co.uk/programmes/b007qgm3 and click on the Big Spring Watch.  Lots of help is given, including a free downloadable nature identification booklet.

Your help is needed! 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 any changes in our climate.
