Local youngsters have singled out the saltwater crocodile as one of the most endangered species in Hong Kong - even though only one has been documented here, and that was a visitor. Sixty per cent of children in a survey chose the Chinese white dolphin as the most endangered. But 17 per cent - the second-largest group, obviously influenced by the saga of Pui Pui, the Yuen Long renegade - chose the saltwater croc. They put it ahead of Romer's tree frog, the black-faced spoonbill and coral reefs. Pui Pui is the only documented salt water crocodile in Hong Kong, thought to have been freed by its owner, while coral comprises about 800 reef-forming species. Asked what they believed Pui Pui needed most, 43 per cent said family, 20 per cent said freedom while 37 per cent thought she could do with some mates. The survey of 500 children aged between six and 14 by the National Geographic Society found that 84 per cent of local youngsters felt wildlife conservation was important and 67 per cent enjoyed reading news stories about wildlife. Speaking at the launch of the 24-hour bilingual National Geographic Wild channel in Hong Kong, marketing vice-president Terri Seow said conservation awareness among local children was heavily influenced by the media. 'Conservation has always been the talk of the town,' Ms Seow said. 'If students know more about other species that require the same protection then efforts to conserve them will increase. Through this channel we hope to promote better understanding of nature by showing visual and compelling stories.' Reptile expert Brady Barr, presenter of National Geographic's Crocodile Chronicles, said he was inspired as a child by documentaries and visits to the zoo, and hoped the new Wetland park and the wildlife channel would breed a new generation of nature lovers. 'A lot of people ask me how I got my job with National Geographic. They think I must have been the best student and had the best opportunities. But in fact, I am a product of institutions like the Wetland Park,' he said. 'I believe 24 hours of wildlife on this new channel will foster a whole new breed of guys and girls like me that share my passion and interest for wild animals.'
