Nature lovers will be invited to cast their votes later this year to identify Hong Kong's most beautiful stream, raising public awareness about conservation at the same time. Co-organised by the Tai Po Environmental Association and the Hong Kong Federation of Countryside Activities, the poll is the first of its kind in the city. Votes can be cast from May to August. The poll comes after the eco-vandalism of the Tung Chung stream, which was ruined by illegal excavation by villagers, and the concreting over of two streams in Sai Kung. Voters will be able to pick one of 10 shortlisted streams. The candidates are Ping Nam, Wang Chung, Sheung Luk, Ma Tai, Ng Tung Chai, Tai Shing, Lin Fa, Wong Lung, Ling Fung, and Shui Lo Cho streams. Most of the streams are located in the northern New Territories, including Ng Tung Chai stream in Tai Mo Shan, which has the highest waterfall in Hong Kong. 'We hope the poll will raise public understanding of the ecology of the streams, and the happiness they bring us and the threats facing them,' said Tsim Siu-tai, conservation adviser to Tai Po Environmental Association. Votes can be lodged at www.taipoea.org or www.hkfca.org.hk .
