Monty Don presents Shared Planet, the series that looks at the crunch point between human population and the natural world. In this programme Howard Stableford reports from Conneticut on the complex decline of the once very ubiquitous Chimney Swift, a story Monty Don believes is the paradigm for the series. The wider issues of human population and nature are explored in the studio with Lord May, past president of The Royal Society and from Vienna, Professor Wolfgang Lutz, a specialist in human population dynamics.

In traditional Chinese culture the mandarin duck is believed to bring lifelong fidelity to couples and frequently used as symbols for wedding presents or in Chinese art. Formerly abundant in their native Far East, numbers of mandarin ducks have declined due to habitat destruction (mainly logging) and over-hunting. For this Living World, presenter Chris Sperring travels to the river Dart in Devon where starting underneath the busy A38 trunk road he meets up with naturalist John Walters who has been studying a winter roost of mandarin ducks here. In mid-winter up to 100 birds can roost here but in early spring they are beginning to pair up and disperse along the river Dart. Leaving this noisy suburban area, Chris and John then head off up the river to search for pairs of these wonderful tree ducks in the Devonian landscape.

For many the emergence of the daffodil is the real, true harbinger of spring. That flash of yellow across the countryside breathes vitality into a previously grey and dormant winter landscape. There are around 26,000 species of daffodil in the World, however Britain is home to a special collection of true wild daffodils; smaller and less showy than the more usual cultivated stock, but superbly adapted to survive in our cold wet climate. For Living World, presenter Chris Sperring joins botanist Ray Woods in search of one such daffodil, the Tenby daffodil, the National emblem of Wales. This daffodil is unique in that it is found nowhere else on the Planet except around Tenby and southwest Wales. Most often associated with places of habitation, its origins and history are now lost in history, but by the 1800's this species was abundant in hedgerow and field.
