Sand eels are a hugely important part of our marine ecosystem. In fact, the fledgling success of our breeding seabirds entirely depends on them.

Bell heather is our most familiar heather. In summer, it carpets our heaths, woods and coasts with purple-pink flowers that attract all kinds of nectar-loving insects.

The tiny, grey-brown house mouse is one of our most successful mammals. It thrives around buildings but is less likely to be found in our houses these days due to better construction.
