From vast plains spreading across the seabed to intertidal flats exposed by the low tide, mud supports an incredible variety of wildlife.

Hedgerows are one of our most easily encountered wildlife habitats, found lining roads, railways and footpaths, bordering fields and gardens and on the coast.

These grasslands, occupying much of the UK's heavily-grazed upland landscape, are of greater cultural than wildlife interest, but remain a habitat to some scarce and declining species.

From otters to freshwater shrimps, all animals are dependant on an abundant and reliable supply of clean water. Rivers sustain the natural environment, wildlife and people in equal measure.
