(Photograph) - Road hog: of 12 hedgehogs released and radio-tracked in the wild, one died in a motoring accident, one was eaten by badgers, one died of a fatal snout injury and another of pneumonia. The others have settled, mainly in private gardens, according to Nigel Reeve, lecturer in the school of life sciences at Roehampton Institute in London. He has just published Hedgehogs, a book which reviews research in an area where he believes there is great ignorance.
