Britain’s wildlife is in trouble. Wild creatures that have lived here for thousands of years are disappearing, because of pollution and persecution, competition with alien species, changing farming and forestry practices, and climate change. It’s not just rare creatures such as the Scottish wildcat or the red squirrel that are vanishing. Hares and hedgehogs, skylarks and water voles, even the humble house sparrow, are in freefall. But now, at last, there is hope. Author and naturalist Stephen Moss has travelled the length and breadth of the United Kingdom to see just how Britons are fighting back to save the wildlife they love.
