Wildlife-friendly gardening is about making a haven for you, as well as for wildlife. Up to a quarter of a city's area can be made up of gardens. Although each garden on its own may be small. together they form a patchwork linking urban green spaces with nature reserves and the wider countryside. With an estimated 24 million gardens in the UK, the way they are managed can make a big difference for wildlife. Hedgehogs, sparrows, song thrushes and stag beetles are all declining species in the UK If we manage our gardens for wildlife, these creatures and many more will feel the benefits.
