How can people help

Since the 1930s, we have lost almost half of our woodland to intensive agricultural practices and development, resulting in a dramatic loss of habitat for the creatures that live in dead and decaying wood. But you can help our minibeasts: by simply providing a small pile of logs in your garden, you'll make a refuge for everything from shield bugs to wood wasps, and a hunting ground for small mammals, reptiles and amphibians. To find out more about encouraging wildlife into your garden, visit our Wild About Gardens website: a joint initiative with the RHS, there's plenty of facts and tips to get you started.
