Freshwater is the lifeblood of our wild isles. From highland burns in the Scottish Cairngorms to vast mudflats in Norfolk, Sir David Attenborough takes us on a journey from source to sea, following the course of our freshwater as it journeys through our landscapes.
Along the way we meet a host of wildlife that lives in, on and around our rivers, lakes, ponds and lochs, revealing the crucial role that water plays in supporting wildlife of all kinds. Determined Atlantic salmon battle their way upstream in one of the greatest migrations on the planet, beavers slow the flow with their expert dam-building, spiders become deadly assassins, millions of mayfly have mere days to live, and in shocking new behaviour caught on camera, an unlucky raft of young toadlets has to cross a ‘killing zone’ patrolled by carnivorous leeches...a tiny toad’s worst nightmare.
As our rivers slow, they spread out and huge areas of reedbed form. In spring, great crested grebes pair up in a complex and beautiful courtship ceremony, and hobbies – small, agile birds of prey - swoop low to catch dragonflies in the summer sun.
Where our freshwater reaches the sea, vast mudflats can form. These habitats are a magnet to hundreds of thousands of overwintering wading birds, and they in turn attract peregrine falcons – the fastest animal on the planet*.
Whether it’s our rare chalk streams, vast reedbeds, or rich mudflats, freshwater touches almost every corner of the British Isles, and every creature here relies on it.
