Put simply, stepping stones can be anything that will help wildlife to move between isolated fragments of habitat. When pockets of habitat are linked in this way it makes it much easier for wildlife to find food and water, a mate and somewhere safe to raise a family. You could think of them as little service stations where wildlife can rest and refuel on their journeys from place to place.
From adding potted plants along an alleyway, to growing wildflowers on road verges, there are so many different options to choose from. Whichever you pick, providing stepping stones is a great way to not only help wildlife but bring different parts of your community together for a common cause.
