Tai Ho Stream is located in northern Lantau Island. It is a medium-sized natural streams stretching from uplands to the lowland esturay continuously without being channelized and is a Site of Special Scientific Interest. The middle course passes through famrland and woodland reaching mangrove and mudflat in the lower course. There is high species richness of freshwater fish (53 species), including the rare Ayu (Plecoglossus altivelis) and amphibians (10 species), including the famous Romer's Tree Frog (Liuixalus romeri). Rare birds of conservation concern such as Brown Fish Owl (Ketupa zeylonensis) and Swinhoe's Egret (Egretta eulophotes) have been recorded in Tai Ho. Moreover, Tai Ho is included in the List of Priority Sites for Enhanced Conservation ranking the third, just after Mai Po and Sha Lo Tung.
However, Tai Ho is facing severe threats. Since 2001, land developers have been planning to build residential buildings in Pak Mong and Tai Ho Wan, as well as a ecology and monument park. This act would only damage the pristine habitats. In 2004, the government proposed a logistics park outside Tai Ho Wan to boost trading between Mainland China and Hong Kong. In 2014, some villagers destroyed large stretches of mangroves in response to the government's planning control over the building of New Territories Small Houses.
