Скачать или смотреть Exploring British Wildlife: Bluebells | Natural History Museum

Voted Britains favourite flower, the bluebell captures the very spirit of springtime with its intensely coloured carpets appearing in many woodlands in spring. But is it flowering earlier than it used to? Bluebell flowering times can be used as powerful evidence of climate change.

That is why the aim of this year's new survey is to build up a nationwide picture of when bluebells, both native and non-native species, start flowering each year.

Find out more about the different species of bluebell, how they can help us monitor changes in season, and how you can help scientists by taking part in this year's survey: http://www.nhm.ac.uk/bluebells
