Otters in this country are a conservation success story. When Paul Chanin first started studying otters their numbers were so low that they had disappeared entirely from most of England. Over the last forty years they have recovered until, in 2011, otters finally returned to Kent, and are once more present in every English county. Paul Chanin has substantially updated his original book on otters for this new volume. He reports on the results of recent research studies and comments on what is now known about the causes of the decline and the eventual recovery of this charming - and still very elusive - mammal. A feature of Otters is the beautiful and accurate line drawings and cartoons by renowned wildlife artist Guy Troughton. This special edition also features an eight-page gallery of stunning colour photographs.
