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

The stinging nettle is a familiar and common plant, often firmly rooted in our memories after our first, hands-on experience - a prickling irritation that's not forgotten easily!

The wild rock dove is the ancestor to what is probably our most familiar bird - the feral pigeon, which is often found in large numbers in our towns and cities.

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.
