塱原 Long Valley
地點介紹 Site Description
Long Valley is a piece of freshwater wetland at the north of Sheung Shui Downtown. It is a main wintering ground for migratory birds other than Mai Po.
Long Valley is manly farmlands and fish ponds. Among the farmlands are wet farms for planting Water Spinach and Watercress. Long Valley is not affected by habitat fragmentation and has little anthropogenic disturbance. In addition, it is a low land and holds a lot of different small habitats such as Blood Worm ponds and lotus ponds. Hence, over 210 species of birds live there, including the Greater Painted-snipe, Von Schrenck's Bittern and Pallas's Grasshopper Warbler, as well as 25 bird species under special protection.
As for plants, other than vegetables, there are also fruit trees, other trees, shrubs and climbers.
In 2003, KCR started constructing the Lok Ma Chau Spur Line, which passes through Long Valley and caused an uproar. KCR originally planned to adopt a viaduct design, but was strongly objected by green groups, who claimed that the viaduct construction would damage Long Valley's habitats and topography and pose threat to the birds' safety. In the end, an underground tunnel design was used to reduce the effects on the environment.
Since 2005, the Conservancy Association and the Hong Kong Bird Watchign Society have partnered up and been carrying out habitat management, conservation and envrionmental education in Long Valley with grants from the government.
