Meet the rare, obscure, and utterly British species found nowhere else on earth.

Around 70,000 species call Britain home, but how many of them can be found here and only here? Join conservationist James Harding-Morris as he uncovers the stories of our endemic wildlife – the plants, animals and fungi that are unique to these islands.

Determined to give these irreplaceable species their moment in the spotlight, James goes in search of them across the length and breadth of Britain, from wild and rugged Orkney, the only known location for the Orkney vole, down to suburban Plymouth where the horrid ground-weaver spider faces global extinction at the hands of developers. He explores Devon's depths on the hunt for ghostly cave shrimp, seeks out alien fungi on Norfolk roadsides, and traces the tribulations of interrupted brome, the grass that has gone extinct not once, but twice.

Along the way, he meets the experts devoted to the study and survival of these vanishingly rare creatures and plants, determined to save them from the brink of global extinction, often single-handedly. Because many of these species are at risk of disappearing forever, before most of us even realise they exist.

A tapestry of wonder and weirdness, tragedies and triumphs, Endemic celebrates what makes our natural history so special and calls on us all to cherish and protect it.
