FINALIST IN THE PEOPLE'S BOOK PRIZE FOR NON-FICTION 2022/2023 - WRITTEN BY THE WAINWRIGHT-CONSERVATION-PRIZE-WINNING AUTHOR OF REBIRDING. Transform your understanding of the natural world forever and discover the wild forces that once supported Britain's extraordinary natural riches, and could again. Our precious archipelago is ravaged by climate change, bereft of natural ecosystems and lies at the mercy of global warming, flooding, drought and catastrophic biodiversity loss. But could restoring species that once helped protect our islands help turn this crisis around? From familiar yet imperilled honeybees and ancient oak woods to returning natives like beavers and boars, Britain's cornerstone species may hold the key to recovering our biodiversity on land and in our seas. In Cornerstones, we discover how beavers craft wetlands, save fish, encourage otters, and prevent rivers from flooding. We learn how 'disruptive' boars are seasoned butterfly conservationists, why whales are crucial for restoring seabird cities and how wolves and lynx could save our trees, help sequester carbon and protect our most threatened birds. Benedict Macdonald transforms our understanding of the natural world forever, revealing lives that once supported extraordinary natural riches and explaining how humans - the most important cornerstone species of all - can become the greatest stewards of the natural world.
