What is biodiversity and why does it matter? How can everyday observations and online databases help to increase our knowledge about the diversity of species? On this album, Jonathan Silvertown, Professor of Ecology at The Open University, presents a guided tour of iSpot, a nature website that gives anybody and everybody a chance to share their observations and learn more about wildlife. In the audio track, Professor Silvertown describes his work in South Africa, protecting the delicate ecosystem of a unique heath-land habitat called 'fynbos'.
