Great barrier reef presentation

  1. Corals are soft, stationary animals without a backbone!
  2. When the corals die, they leave behind hard structures that are the basis of the reef
  3. Home to 30 different kinds of whales, 6 kinds of turtles, and over 1500 kinds of fish, PLUS sea snakes, sharks, and stingrays!
  4. Home to some of the largest clams in the world!
  5. Found in the shallow waters surrounding Queensland, Australia!
  6. Named one of the seven wonders of the world!
  7. Estimated to be 500,000Years old
  8. It is the largest reef system in the world!
  9. Over 344,400 square kilometers and 1,800 miles long!
  10. 1,200 miles long
  11. It is estimated that by the year 2100, the world will have only 30% of it’s coral reefs
  12. The Great Barrier Marine Park Authority has introduced several plans to help stop this
  13. Lots of the species that are native to the Great Barrier Reef, and only found there are becoming endangered!
  14. Endangered animals are species that are in danger of going extinct
  15. Sharks – whale shark, grey nurse shark, great white shark, freshwater and green sawfish
  16. Marine turtles
  17. Birds
  18. Seals
  19. Whales and dolphins
  20. Dugongs
  21. Shells – helmet shells, triton shells, tridacnid clams
  22. Fish – seahorses, pipefish, sea dragons, potato cod, Queensland Grouper, barramundi cod, Maori wrasse, all other grouper over 100 cm
  23. Seasnakes
  24. Pollution – Toxic Spills, and groundings
  25. Over-fishing and poaching
  26. Natural Disasters, such as hurricanes, and tropical storms
  27. Physical Damage
  28. The water temperature is expected to rise 1.8-5.4 degrees Fahrenheit
  29. Rising climate makes ice bergs melt, which makes the ocean rise, estimates are at 3 mm per year
  30. Causes stress to the very delicate corals:
  31. They become unfit hosts for and discharge the microorganisms which live on them.
  32. Causes Coral Bleaching, which is when the corals begin to lose their colorations
  33. Pesticides and fertilizers run off into these rivers and poison the inhabitants.
  34. Spreads disease among corals
  35. Copper from industries stunts polyp development
  36. Ships take “shortcuts” through the reef, and release exhausts and leak oils that suffocate the corals and other organisms, into the waters
  37. Sediment: solid particles settle into the water and smother the environment
  38. Can result in the reef being buried!
  39. Naturally predatory species are over-fished, causing species lower on the food chain to grow out of control
  40. Likewise, if species low on the food chain are diminished, natural predators will die due to lack of food.
  41. Fishing increases pollution on the reef, because of the ships
  42. Many of the endangered species are poached, for flavors, and high rates of pay
  43. Reduces life span and reproduction of species (Keller et. al, 2009).
  44. Increase sea levels!
  45. Dump too much freshwater into the sea
  46. The corals, polyps and all other inhabitants are salt water friendly
  47. Freshwater decreases coral growth
  48. Rising water levels increase run off into the rivers and, subsequently into the sea!
  49. Touching: Suntan lotions and oils wash off and cause damage to the reef
  50. Boats drop anchors in the reef and cause physical damage
  51. Increases pollution, also
  52. Littering: leaving foreign things in the reef
  53. Fishes may ingest harmful matter
  54. Chemicals in the litter can be harmful
  55. Much of the litter does not biodegrade
  56. Propellers hit marine animals, such as endangered dugongs and turtles
  57. Outlook Report
  58. Biodiversity Strategy
  59. Employs 15 Advisory Committees
  60. Committed to the long-term protection of the reef
  61. Reef HQ Aquarium – education center run by the GBRMPA
  62. 25 Year plan:
  63. Conservation
  64. Resource Management
  65. Education, and Communication
  66. Research and Monitoring
  67. Provides a report of the management of the Great Barrier Reef
  68. Summarizes the past and present management of the Great Barrier Reef
  69. Highlights:
  70. The GBR is one of the most extraordinary ecosystems in the world
  71. Key issues to be addressed within the Park:
  72. Climate
  73. Declining water quality
  74. Loss of habitat
  75. No other place in the world is home to as many different plant and animal species living in harmony with each other
  76. It is imperative that we preserve the diversity of this ecosystem
  77. Aims to guide and help coordinate management actions that will protect and conserve biodiversity in the Great Barrier Reef, (GBRMPA, August 2010).
  78. Conserves the diversity of the habitat as well as it inhabitants
  79. Provides a framework for how biodiversity is managaged (GBRMPA, 2010).
  80. Completes assessments on progress
  81. Identifies problems, fall-backs, and prioritizes threats
  82. 2 Goals:
  83. immediate goal - to halt and reverse the decline in water quality entering the Reef by 2013 (Qld Gov, 2009)
  84. long term goal - to ensure that by 2020 the quality of water quality entering the Reef from adjacent catchments has no detrimental impact on the health and resilience of the Great Barrier Reef. (Qld Gov, 2009)
  85. Implement strategies on the farms surrounding the area
  86. Protects 33% of the reef from commercial and recreational fishing!
  87. Identifies endangered species, and outlines steps to protect them
  88. Allows native peoples to fish the reef
