In this second of three podcasts on the theme of nature, Barbara and David are joined by two guests: Jonathan Preston, Conservation Manager for the Norfolk Wildlife Trust, one a series of such posts he has held across the country over three decades, with current responsibility for wildlife conservation at 30 different sites in Norfolk; and Nicola Davies, who trained as a biologist, was an original presenter on the BBC’s The Really Wild Show, and is the acclaimed author of over 80 illustrated children’s books on animals, habitats, ecology and the sea. Jonathan, to begin, please can you introduce us to what nature conservation is for, and broadly how it’s done?
