Wild Kingdom - Bringing Back Britain's Wildlife

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.
