All over the world, animals are constantly on the move, travelling to find mates, forage for food and seek safety and shelter. But what happens when man-made barriers get in the way? From motorways and railways to housing developments and gas pipelines, humans have made it harder for animals to get to where they need to go. But now humans are reconnecting wild spaces and helping animals of all shapes and sizes find safe passage. They're using overpasses, underpasses, rope bridges and ingenious engineering to move between fragmented forests and habitats. From tiny toadlets to the world's largest mammals, animals cross over and under, up above and down below. With 18 true stories of animal crossings written by Rachel Ip and brought to life by Katie Hickey's artwork, 'Wild Crossings' is the perfect blend of engineering and nature stories for children.
