  1. Conserving Hong Kong’s wildlife Resources

  2. Why we need to conserve wildlife in Hong Kong?

  3. Geography of Hong Kong - HK is well in side the tropics Tropic of Cancer 北回歸線

  4. Aquatic environment : west - Due to the Pearl River influence, more brackish water habitats in the western side of HK.

  5. Deep Bay – mud flat

  6. Mangrove

  7. Aquatic environment : east - The stronger oceanic current from the Pacific created more marine habitats in the eastern waters of HK

  8. Terrestrial environment: • hilly area (75%)

  9. secondary forest (8%) e.g. Tai Po Ngau

  10. Fung Shui Wood < 1% Planted woodland 4.5%

  11. Hong Kong Endangered species Reasons for extinction i. Destruction of habitats ii. Reckless predation of wild animals iii. Economic development: polllution

  12. Hong Kong Endangered species • Mammals • Marine • Only two species regularly occur in HK waters • i. 江豚 Finless porpoise • More common in eastern HK waters e.g. Sai Kung • ii. 中華白海豚 Chinese White Dolphin • More common in the western waters of HK e.g. North Lantau. A marine park at Sha Chau and Lung Kwu Chau has been set up to protect this species.

  13. b. amphibians • i. HK Newt • Occur in clean mountain streams • Of potential global importance • Once thought endemic to HK, recently found in various parts of Guangdong.

  14. ii. Romer’s Tree Frog • Endemic to HK and globally important • Found on several islands only • Once threatened by the Chep Lap Kok Airport development • The former Chek Lap Kok population has been relocated to several places on the New Territories

  15. b. birds • Greater Painted Snipe 彩 鷸 • A locally important species. Two sites (nesting) found in HK, one at Kam Tin, the other one at Long Valley • 2. Black-faced Spoonbill 黑臉琶鷺 • - Globally threatened! World population estimated at 660! Nest at Korea and northest China. Winter at Japan, Taiwan, HK, Macau, and north Vietnam. About 138 – 152 winter at Mai Po in the last few years.

  16. 3. White-bellied Sea Eagle 白腹海鵰 • - Regionally important. About ten pairs regularly nesting along HK’s coast. The pair near HK Disneyland may be affected by the theme park development.

  17. d. Others • 馬蹄蟹 Horseshoe Crab • Threatened by hunting and habitat destruction.

  18. -Insect • 黃扇蝶 Birdwing Butterfly Triodes helena • Protected in HK • Freshwater fresh • 黑歧尾鬥魚 Black Paradise Fish Macropodus hongkongensis • Identity recently confirmed • Globally important species

  19. Group discussion Suggest three ways to conserve biodiversity in HK. • concrete - actionable - effective • innovative / already implemented You may refer to p.10-11 of the notes for some hints

  20. 3.What can we do? a. establish sanctuary area • 38% land already protected good: forest, woodland, grassland poor: wetland, field, fung-shui wood

  21. b. Turning most grassland and shrubland back to forest

  22. e.g. Prevention of hill fire e.g. Re-plantation

  23. c. Stop illegal hunting 小靈貓 豹貓

  24. 棕鼯鼠 d. Reintroduce lost species 白鷴

  25. e. Prevent the establishment of foreign species Mikania 薇金菊 Oryzias curvinotus 弓背青魚將 Gambusia affinis食蚊魚

  26. f. Develop ecotour
