    Angel Carney, 2010
  • What is A Reef?
    • Coral reefs are diverse ecosystems made of tiny living animals, called corals.
    • Corals are soft, stationary animals without a backbone!
    • When the corals die, they leave behind hard structures that are the basis of the reef
    • Home to 30 different kinds of whales, 6 kinds of turtles, and over 1500 kinds of fish, PLUS sea snakes, sharks, and stingrays!
    • Home to some of the largest clams in the world!
    • Microscopic algae live on the corals and through photosynthesis, the corals “steal” nutrients from the algau, giving them their vibrant colors
    Angel Carney, 2010
  • Meet the Great Barrier Reef
    • Barrier Reefs are those that form parallel to a land mass, usually several miles away
    • Found in the shallow waters surrounding Queensland, Australia!
    • Named one of the seven wonders of the world!
    • Estimated to be 500,000Years old
    • It is the largest reef system in the world!
    • Over 344,400 square kilometers and 1,800 miles long!
    • 1,200 miles long
    • Can be seen from space!
    Angel Carney, 2010
  • The Problem:
    • Due to many outside influences, Great Barrier Reef is in peril!
    • It is estimated that by the year 2100, the world will have only 30% of it’s coral reefs
    • The Great Barrier Marine Park Authority has introduced several plans to help stop this
    • Lots of the species that are native to the Great Barrier Reef, and only found there are becoming endangered!
    • Endangered animals are species that are in danger of going extinct
    • Many of the species on the reef are exclusive to this area, which means when they are gone from the reef, they are gone from the planet
    Angel Carney, 2010
  • The Problem: Endangered Species
    • The following are the chief concern of the Marine Park Authority. There are MANY other species in danger as well.
    • Sharks – whale shark, grey nurse shark, great white shark, freshwater and green sawfish
    • Marine turtles
    • Birds
    • Seals
    • Whales and dolphins
    • Dugongs
    • Shells – helmet shells, triton shells, tridacnid clams
    • Fish – seahorses, pipefish, sea dragons, potato cod, Queensland Grouper, barramundi cod, Maori wrasse, all other grouper over 100 cm
    • Seasnakes
    • Crocodiles
    Angel Carney, 2010
  • Causes of The Problem:
    • Climate Change
    • Pollution – Toxic Spills, and groundings
    • Over-fishing and poaching
    • Natural Disasters, such as hurricanes, and tropical storms
    • Physical Damage
    • Water Quality
    Angel Carney, 2010
    • Every part of the reef is affected by the climate changes
    • The water temperature is expected to rise 1.8-5.4 degrees Fahrenheit
    • Rising climate makes ice bergs melt, which makes the ocean rise, estimates are at 3 mm per year
    • Causes stress to the very delicate corals:
    • They become unfit hosts for and discharge the microorganisms which live on them.
    • Causes Coral Bleaching, which is when the corals begin to lose their colorations
    • Ocean acidification – Increasing temperatures cause increased carbon dioxide to be absorbed by the ocean waters.
    Angel Carney, 2010
    • 30 Rivers in Queensland dump into the waters around the reef
    • Pesticides and fertilizers run off into these rivers and poison the inhabitants.
    • Spreads disease among corals
    • Copper from industries stunts polyp development
    • Ships take “shortcuts” through the reef, and release exhausts and leak oils that suffocate the corals and other organisms, into the waters
    • Sediment: solid particles settle into the water and smother the environment
    • Can result in the reef being buried!
    • Blocks sunlight so the microorganisms cannot photosynthesize and give the coral their colors
    Angel Carney, 2010
    • Many species of the reef are increasing in popularity as “delicacies”
    • Naturally predatory species are over-fished, causing species lower on the food chain to grow out of control
    • Likewise, if species low on the food chain are diminished, natural predators will die due to lack of food.
    • Fishing increases pollution on the reef, because of the ships
    • Many of the endangered species are poached, for flavors, and high rates of pay
    • Reduces life span and reproduction of species (Keller et. al, 2009).
    • Nets dragged across the sea floor cause damage to the habitat.
    Angel Carney, 2010
    • String storm winds and waves break the corals
    • Increase sea levels!
    • Dump too much freshwater into the sea
    • The corals, polyps and all other inhabitants are salt water friendly
    • Freshwater decreases coral growth
    • Rising water levels increase run off into the rivers and, subsequently into the sea!
    • Diluting the salt water contributes to coral bleaching and death of the polyps
    Angel Carney, 2010
    • Stealing: Tourists rip pieces of the coral, and polyps from the reef
    • Touching: Suntan lotions and oils wash off and cause damage to the reef
    • Boats drop anchors in the reef and cause physical damage
    • Increases pollution, also
    • Littering: leaving foreign things in the reef
    • Fishes may ingest harmful matter
    • Chemicals in the litter can be harmful
    • Much of the litter does not biodegrade
    • Propellers hit marine animals, such as endangered dugongs and turtles
    • Snorkel fins damage corals when stricken
    Angel Carney, 2010
  • Solutions for The Problem
    • Great Barrier Reef Marine Park Authority
    • Outlook Report
    • Biodiversity Strategy
    • Reef water Protection Plan
    Angel Carney, 2010
  • Great Barrier Reef Marine Park Authority
    • Manages the Great Barrier Reef Marine Park
    • Employs 15 Advisory Committees
    • Committed to the long-term protection of the reef
    • Reef HQ Aquarium – education center run by the GBRMPA
    • 25 Year plan:
    • Conservation
    • Resource Management
    • Education, and Communication
    • Research and Monitoring
    • Management Processes
    Angel Carney, 2010
  • Great Barrier Reef Outlook Report 2009
    • A summary of the status and future of the Great Barrier Reef
    • Provides a report of the management of the Great Barrier Reef
    • Summarizes the past and present management of the Great Barrier Reef
    • Highlights:
    • The GBR is one of the most extraordinary ecosystems in the world
    • Key issues to be addressed within the Park:
    • Climate
    • Declining water quality
    • Loss of habitat
    • Fishing
    Angel Carney, 2010
  • Bio-Diversity Strategy
    • Great Barrier Reef is home to a VAST variety of species
    • No other place in the world is home to as many different plant and animal species living in harmony with each other
    • It is imperative that we preserve the diversity of this ecosystem
    • Aims to guide and help coordinate management actions that will protect and conserve biodiversity in the Great Barrier Reef, (GBRMPA, August 2010).
    • Conserves the diversity of the habitat as well as it inhabitants
    • Provides a framework for how biodiversity is managaged (GBRMPA, 2010).
    • Completes assessments on progress
    • Identifies problems, fall-backs, and prioritizes threats
    • Manufactures and distributes publications to the public
    Angel Carney, 2010
  • Reef water protection plan
    • Launched in 2003, revised 2009
    • 2 Goals:
    • immediate goal - to halt and reverse the decline in water quality entering the Reef by 2013 (Qld Gov, 2009)
    • 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)
    • Implement strategies on the farms surrounding the area
    • Enact, Review, oversee and stay on top of policies
    Angel Carney, 2010
  • Reef Protection Plan
    • Goal: To protect the Great Barrier Reef
    • Protects 33% of the reef from commercial and recreational fishing!
    • Identifies endangered species, and outlines steps to protect them
    • Allows native peoples to fish the reef
    • Prohibits removal of any part of the reef or any inhabitant
    Angel Carney, 2010
  • Conclusion:
    The Great Barrier Reef has been recognized as a World Heritage Site. It covers an area larger than the size of Italy. Te Great Barrier Reef is home to a very wide variety of corals, polyps, plants, animals, fish, and more organisms and is more than 500,000 years old. It is imperative that we preserve this treasure trove under the sea. Many human practices are killing The Great Barrier Reef, but through knowledge we can spread the word and help combat the destruction of this natural wonder of the Earth. Please, help, spread the word!
