The importance of Long Valley

Discover the significance of Long Valley, the largest remaining freshwater wetland in the northwestern part of the New Territories in Hong Kong. With over 210 bird species and several vulnerable and near-threatened species, Long Valley is a crucial habitat that must be protected from habitat destruction and environmental disturbance. Learn about the potential threats faced by Chinese White Dolphins, Romer's Tree Frog, and Black-faced Spoonbills, and the measures taken by Hong Kong to preserve these species and their habitats.

Presentation Transcript

  1. The importance of Long Valley Largest remaining freshwater wetland in the northwestern part of the New Territories More than 210 bird species have been recorded, accounting for nearly half of the Hong Kong list. Eleven species are regarded as "vulnerable" and "near-threatened" according to global standards

  2. Effect of the original KCRC development plan The fragmentation of habitats will lead to increased environmental disturbance, which will seriously affect the habitation of wildlife. Habitat destruction is permanent and reduce the chance of birds' survival and cause soil and water quality deterioration.

  3. Chinese White Dolphins

  4. Potential threats • disturbance and destruction of natural habitats • pollution • mistaken predation • hit by ships • reduction of food supply

  5. Protection by HK Sha Chau and Lung Kwu Chau, the main habitat of the dolphins are designated to be Marine Park in November 1996. can avoid threats such as being hit by high-speed ships and being hurt in destructive fishery activities like shrimp trawling and double trawling.

  6. Protection by HK To improve water quality and reduce possible threats caused by toxic pollutants in the water by setting up a series of waste disposal system and upgrading the existing sewage treatment facilities. Deploys artificial reefs in marine parks and other sites in order to rebuild the local fish stock and therefore enhance the availability of the dolphins' preys.

  7. Romer’s Tree Frog

  8. Potential threats Habitat destruction: Romer's Tree Frog is endemic to Hong Kong and has only been recorded in some locations, namely Lantau, Lamma, Po Toi and previously in Chek Lap Kok.

  9. Protection by HK Part of Ngong Ping in Lantau which support the largest population of the frog has been designated as a Site of Special Scientific Interest (SSSI) in May 1999 Development within the site is subject to statutory planning control

  10. Black-faced Spoonbill

  11. Potential threats Habitat destruction: The Lok Ma Chau plan of KCRC will affect 5% of the world's wetlands. 9.5 hectares of fish ponds will be destroyed in that area to build Lok Ma Chau Station. KCRC claimed that this would increase the environmental value of the neighbouring 28.5 hectares of fish ponds. However, the fact is that the 28.5 hectares of fish pond are originally wetlands.
