Although it's classed as Britain’s only 'desert' - and despite its bleak aspect in the depths of winter - the shingle headland of Dungeness is home to an incredible array of wildlife, plants and birdlife. Matt meets Owen Leyshon, who's been the warden of the national nature reserve here for the past 25 years, to find out more about the rich and diverse species that make Dungeness their home.He also discovers that this is a landscape on the move – one that is growing outward at a rate of up to two metres a year. Matt also joins a group of volunteers to tackle an important winter job that keeps some of the unique species here in tip-top condition – clearing bramble from the blackthorn bushes that grow on the headland.
